to solve the environmental problems

10 Environmental Problems and Solutions in 2023

September 6, 2022

Graham Sawrey

There are so many environmental problems we face today, and they all have to be addressed. But which environmental issues demand our attention now?

We’ll discuss 10 environmental problems and solutions that we can work on now to change our collective future for the better!

10 Environmental Problems and Solutions

Want to know even more? Check out our List of Environmental Issues Examples where we discuss the 30 biggest threats earth faces today for a more in-depth understanding of environmental problems.

Here are the top 10 environmental issues that require immediate attention for the health of our planet and our own survival.

• Climate Change
• Water Pollution
• Air Pollution
• Natural Resource Depletion
• Waste Management
• Urban Sprawl
• Energy Consumption
• Environmental Degradation
• Deforestation
• Recycling Inefficiencies

We’ll discuss these top 10 environmental problems in detail and offer some real-world solutions to each one.

There is no magic bullet solution for the environmental issues we face. The real solution will come when individuals choose to make decisions in favor of the earth’s welfare .

When billions of us combine a lot of small actions they add up to a big impact on the earth.

1. Climate Change

Climate change is a massive topic. Inside this topic are all the subtopics and environmental problems that add up to climate change.

Climate change is the term we use to refer to the changing atmospheric conditions that affect life on earth.

• Global warming
• The greenhouse effect
• Increased saturation of atmospheric carbon dioxide
• Polar ice melt
• Rising seawater levels
• Ozone layer depletion

These things are intertwined and many of them have the same root cause – the main one is the burning of fossil fuels.

However, along with increased carbon dioxide output from fossil fuels, there are mainly CFCs and halons though other substances also destroy ozone molecules.

These substances are found in aerosols, refrigerants (like air conditioners) and other machinery. CFCs are banned, but other ozone-destroying chemicals are still in use.

Depletion of the ozone layer allows more UVB rays to get through the atmosphere which has a warming effect in the atmosphere of the globe. This changes weather patterns and climate expectations everywhere.

Climate Change Solutions

The solutions to climate change involve viewing the world differently than we currently do as a global culture.

We view the world as something to use. We want to get as much as we can while it’s available. This is causing us to use things we don’t need, create waste, and deplete our resources too fast.

Here are a few things we can do to help combat climate change.

• Drive less often and less far. If there is an option to walk, ride a bike, carpool, or use public transportation then use those options first to help decrease your carbon footprint.
• Reuse things instead of throwing them away. Americans seem to view recyclables as the way forward but they have limitations. They help us to reuse existing resources, but an even better choice is to choose reusable items every chance we get.
• Aim for zero waste. Think about it before you buy. Choose to invest your money in things that will last a long time and can be reused or upcycled instead of thrown away. The world is awash in used cheap clothing, single-use plastics, and cheap appliances that are recyclable yet sit in filthy heaps.
• Get involved. Too many people like to talk about climate change and even yell about climate change but don’t do anything to solve it. Work to increase recycling facilities in your area, educate your community about reusables, and plant native species in your town.
• Get Renewable Energy. Renewable energy is a must. Buying an EV car isn’t enough because plugging into a fossil fuel electric grid just perpetuates the problem. Investigate your own chain of energy and opt for the cleanest energy you can afford.

Climate change is a real environmental issue and it’s full of uncertainties. One thing we know is that the decisions we make today can have a major impact on the quality of life on planet earth in the future.

2. Water Pollution

Water pollution includes marine pollution and freshwater pollution. Let’s take a look at both.

Marine pollution is largely caused by nitrogen that washes away from inland soils and drains into the ocean water.

The excess nitrogen creates algae blooms that prevent sunlight and oxygen from penetrating into the ocean water.

This creates a hypoxic environment called a “dead zone” where fish, crustaceans, and sea mammals can’t live. Mobile marine animals leave the area. Immobile marine life dies.

This is the primary cause of our loss of coral reefs around the globe.

Marine pollution also takes the form of trash and recyclables that wash into the ocean and form massive flotillas of rubbish .

Freshwater pollution refers to the pollution of inland water like rivers, lakes, and reservoirs. We rely on these bodies of water for our drinking water, but they are quickly becoming too polluted to drink.

Freshwater pollution also happens due to nitrogen in the water , but it can also be the result of things people do.

• Trash that ends up in the water
• Sewer treatment plant releases (treated and untreated)
• Dirty stormwater runoff
• Pharmaceuticals, detergents, and other things people put in the water system
• Heavy metals like lead and mercury

Some of these things we can’t avoid, but a lot of it is preventable.

Water Pollution Solutions

The effects of pollution could be minimized and possibly healed if we began to consciously make decisions that will protect our watershed instead of polluting it.

• Farmers can use cover crops to fix nitrogen in the soil . It’s an investment, not an overnight fix, but it will make the biggest impact on the health of the oceans and will eventually eliminate dead zones.
• Homeowners can use as little culinary water as possible for watering outdoor plants. Try xeriscaping to save water. Install rain barrels to collect free water to use on outdoor plants and trees.
• Dispose of medicines, motor oil, household chemicals, and paint in the proper facilities so they stay out of the watershed.
• Eat organic as much as you can. This isn’t fail-proof, but most organic farms rely on natural sources of nitrogen rather than synthetic nitrogen to increase crop yields.
• Be happy with imperfect produce. There is a massive global cost to get those perfect fruits and vegetables. They’re treated with pesticides, herbicides, and chemical fertilizers to make them lovely. Go natural to encourage farmers who want to save the planet.
• Enjoy water sports without a motor. You can greatly reduce your own impact on inland water supplies by enjoying muscle-powered water sports that don’t introduce oils, gasoline, and exhaust particulates into the water supply.

Think about how you’re using our precious water resources. Clean water is so easy to get in developed countries that we tend to forget the watershed it comes from.

That watershed needs our protection to continue to provide us with the clean water we need to survive.

3. Air Pollution

Air pollution is what we call the suspended particulates that become part of the atmospheric gases that we breathe.

We’re not running out of oxygen. The earth has plenty of oxygen. The problem is that the concentration of carbon dioxide is increasing disproportionately and it’s pretty much all our fault.

There is a natural carbon dioxide cycle that we have with all of the plants on the planet. We naturally produce carbon dioxide, and they breathe it in and convert it to oxygen.

In a natural state, this would be in perfect balance.

However, when we burn fossil fuels we pump massive amounts of carbon dioxide into the atmosphere that can’t be offset by the plants in the world.

Furthermore, the carbon dioxide is mixed with a slurry of carcinogens and toxins like methane, formaldehyde, phosphorus, styrene, and more.

Curious to see the full list? The EPA has a list of 188 air pollutants . Nobody benefits from breathing in these compounds.

Air pollution affects everything – us, plants, animals, all water on the planet, and marine fish and mammals.

Air pollution causes and effects have to be clearly understood to really grasp the solutions that we have to implement to clear the air.

Air Pollution Solutions

The biggest solution we can implement is the switch to clean alternative energy sources because fossil fuels are the biggest polluters on the planet.

However, we have to be clear that there isn’t a totally clean energy solution .

• Solar panels are made with coal and require toxic waste disposal when they’re decommissioned.
• Wind turbines have some recyclable parts but the huge fiberglass parts end up in landfills. One of the pros of wind energy is that wind turbines produce zero-cost electricity for about 10 years.
• Nuclear energy pros and cons are hotly debated. It’s a dependable and safe energy source that produces zero carbon emissions . However, uranium mining and disposal cause major environmental hazards.
• One of the advantages of biomass electricity that it creates fewer carbons than fossil fuels. However, biomass production is resulting in deforestation .

Having said all that, we still have to choose these alternative energy sources over straight-up fossil fuel consumption.

Fossil fuels are the dirtiest sources of energy that we have and they contribute the most to the dirty air that we suffer from around the world.

• Limit your time on the road. Vehicle emissions are responsible for most of the dirty air that’s found in cities and communities around the world.
• Turn off the lights and turn down the heat. Electricity usage is directly tied to fossil fuel consumption for powering the electrical grid in many areas.
• Help plant trees. You can plant native tree species in your own town to help clean the air.
• Contribute to rainforest reforestation projects that aim to help strengthen the world’s clean air and biodiversity.
• Choose reusable items and avoid using plastics as much as possible. Manufacturing single-use items contribute a lot to air pollution.

Reducing dependence on fossil fuels will go the farthest in clearing the air around the world.

4. Natural Resource Depletion

The world is full of natural resources. A natural resource is anything that we can use to live or make something from.

Some natural resources examples include:

• Fossil fuels

The world is full of natural resources that we use to enable life as we know it. Natural resources feed us, give us electricity, wire our laptops, and keep us hydrated.

The problem is not all natural resources are renewable . Coal, natural gas, uranium, gold, and even salt are natural resources we depend on but once they’re used up we have no more.

This is why we have to focus on stewarding our renewable natural resources.

• Keeping our water clean
• Collecting sunlight for energy
• Ensuring that fisheries are not over-harvested
• Keeping soil as clean as possible – avoiding the use of pesticides, herbicides, and chemical fertilizers
• Managing timber stands wisely so that we aren’t using more trees than we can replenish in several decades.

When we overuse our natural resources we get a short-term payoff but a long-term loss.

For example, establishing reservoirs in the southwest was a good idea 90 years ago. It allowed the development of desert areas.

However, as communities expand across arid areas under the assumption that established water sources will be reliable, the water sources are being used faster than they can naturally replenish.

Natural Resource Depletion Solutions

One of the main natural resources that we’re depleting is fossil fuel. It is not only going away, but it’s also ruining our planet as we use it for fuel and energy.

Switching to cleaner energy sources is a non-negotiable for solving our climate crisis, but we also have to focus on decreasing our need for energy .

Here are some good ways to decrease your own energy demand so we use fewer natural resources to produce electricity.

• Use less air conditioning in the summer. Willingness to be a little warm will go a long way toward decreasing your contribution to air pollution.
• Use less heat in the winter. Wear a sweater and some slippers instead of cranking up the heat.
• Get up and go to bed with the sun. This is harder in the winter, but by adjusting your waking and sleeping schedule to be more in tune with the sun you’ll feel better and use less electricity in the morning and at night.
• Help to plant trees. Again, replenishing the world’s forests help ensure that our air is healthy and that we have timber stands ready to harvest in the future.
• Waste less food. This doesn’t mean cleaning your plate. This means putting less on it in the first place. Food waste begins at the store and it can end there too.
• Eat whole foods. Whole, natural foods don’t require processing. This means that there isn’t a ton of electricity and fossil fuels going into the production of what you eat. Whole foods are better for the environment and better for your body.
• Refill your water bottle. The majority of single-use plastics that are wandering around in the environment are plastic water bottles. Get a sturdy reusable bottle and refill it. You can keep thousands of water bottles out of the waste stream in your lifetime.

By focusing on sustainability we can help to reduce our dependence on non-renewable resources and help to conserve the resources that we have so they last longer.

5. Waste Management

Waste management has come a long way in the last decade, but it has a long way to go in certain areas of the United States.

According to the EPA, the total waste production in the United States averages out to 4.9 pounds per person per day . This includes all sorts of trash that is binned and collected.

• Recyclables (plastic, paper, glass)
• Landfill items that can’t be recycled
• Grass clippings
• Electronics
• Appliances, etc.

50% of the waste stream goes into landfills .

About 32% of the waste collected in the United States gets recycled or composted .

Nearly 12% gets burned as “biomass” to generate electricity.

Around 6% of the waste is food waste that gets treated in other ways. It might be used in animal feed, turned into fertilizer, used in the creation of biochemicals, or other methods of disposal or reuse.

It’s clear that the US has made a concerted effort to deal with waste streams. The problem is that the amount of waste generated per person is growing drastically.

In 1980 each person generated about 3.66 pounds per day. In 2018 that figure had risen to 4.9 pounds per day. This is the trend that we must change.

Worldwide waste production equals about 1.63 pounds per person with the bulk of that waste being generated in highly developed countries.

Though developing countries don’t tend to generate nearly as much waste per person, they don’t have any safe waste disposal infrastructure which leads to the creation of massive open dumps .

All landfills emit tons of greenhouse gases – mostly methane and carbon dioxide. This is another major contributor to global warming.

While recycling efforts in the United States and elsewhere have produced great results, the recycling waste stream produces much more material than can be currently recycled – ending in waste.

Waste Management Solutions

Waste management must be solved worldwide, but the only thing we can affect is our own consumption and waste patterns.

If each of us becomes wiser consumers we can have a dramatic impact on the waste streams and the carbon emissions from them.

• Waste stops at the store. We can’t impact how much production waste there is unless we stop supporting it with our money. Less demand equals less production.
• Choose reusables. The best purchases are things that can be used hundreds of times before they’re broken or used up.
• Choose recyclables. The recycling stream is quickly outpacing available recycling facilities, so this still isn’t the best choice, though it’s better than throwing things in the landfill.
• Don’t buy more food than you can eat. Some areas have food composting programs, but when food is thrown away it also releases greenhouse gases. Don’t fill your garbage can with food. Reduce your waste and compost food waste if you can. That will also help increase soil health.
• Lobby for recycling. There are billions of dollars being spent on United States “infrastructure.” Citizens need to raise awareness of the need for more and bigger recycling centers so the United States can process its own rubbish.
• Lobby for action. Certain landfills are known as “super emitters.” If local authorities and national politicians will focus on cleaning up the emissions from these sites it will make a huge difference.

In the case of waste streams, part of the responsibility lies with municipal governments to handle waste more cleanly.

The other part of the responsibility lies with the citizens. We are the ones generating the waste. We can all do our part to cut down on our own waste as much as possible.

6. Urban Sprawl

Urban sprawl is the term used to describe the way that cities spread from an urban center into widening suburban neighborhoods. Dwellings go from high-density to low-density, taking up more land.

Urban sprawl is characterized by land use and natural resource consumption .

Undeveloped land that was farmland, ranchland, native plants and soil, or forest is paved over for low-density housing and new strip malls, grocery stores, and restaurant chains.

Here are key takeaways you should know about Urban Sprawl.

• These sprawling areas greatly tax the water supply in the area because the new parks, city strips, lawns, and gardens have to be watered continuously to keep their nice appearance.
• Urban sprawl is a major contributor to the carbon emissions from vehicles . People must commute from sprawling areas into the downtown area for work and school. This increases time on the road. In the worst cases, these vehicles idle while they’re stuck in traffic.
• Urban sprawl creates a need for additional garbage processing resources, greenspace planning, freshwater wells, water treatment plants, waste treatment plants, power plants, substations, and more.

Many of these things aren’t bad, and urban sprawl is often the natural outflow of living in a prosperous area .

It can also be a sign that the municipal government is not keeping the urban areas clean and safe.

Regardless, it is a style of living that uses many more resources than a high-density urban lifestyle.

Some cities including the Dallas/Ft. Worth area and Los Angeles are experiencing increasing urban density as more residents refurbish downtown areas to make them desirable neighborhoods.

Urban Sprawl Solutions

There aren’t any surefire solutions to urban sprawl. The fact is that people move away from urban areas for many reasons – not all of which can be solved.

Here are a few things that local governments can do to encourage people to adopt a high-density housing lifestyle in urban areas.

• Keep residents safe. When people and businesses don’t feel safe in an area they move. Most of the time they choose to move into a suburban or rural area that feels safer. When cities put the safety of residents first they enjoy the prosperity that a thriving urban core brings.
• Focus on key infrastructure. Garbage services, stormwater runoff, sewage treatment, and traffic controls make a big difference in the quality of life in urban areas. When the urban areas feel dirty and congested people move out of the city.
• Encourage community spirit. Cities that find ways to involve citizens in city life enjoy a much higher sense of community pride. This benefits everyone because people who take pride in their community work harder to keep it clean and safe.
• Keep taxes fair. Many people choose to live outside of municipal boundaries because property taxes are much lower in unincorporated areas. Cities that cut fiscal waste can also keep property taxes lower while providing excellent city services.

Over time cities can turn urban life into a desirable living situation for many, diminishing the exodus to outlying areas and helping to curb the rapidity of urban sprawl.

7. Energy Consumption

Our overall high energy consumption is the main contributor to climate change because 61% of the electricity generated in the United States is from burning fossil fuels.

So, on top of burning fossil fuels to commute from sprawling communities, we are also burning fossil fuels to charge our EV cars , keep the air conditioners running, and keep the lights on.

There is no denying the negative impact that our high energy consumption has on the planet, but we also rely on it for our highly technological way of life.

For example, let’s take a look at data centers . The world relies on data centers.

They serve all of your cloud storage, social media content, online shopping, virtual worlds, game streaming, on-demand entertainment, and remote workflows.

Right now, data centers alone consume about 2% of all the energy generated in the United States, and that number is growing as data centers pop up everywhere to handle cloud storage needs.

We can’t just stop feeding data centers because we rely on them for work, data storage, and socialization. Younger generations are more dependent on data center capacity and speed than ever before .

That’s just one example of an energy consumer that we can’t just shut down to save the planet. So we have to look at home to decrease energy consumption .

Energy Consumption Solutions

As with most solutions to our global environmental crisis, the answer begins at home.

• Shut off the lights and opt for sunshine. Even small amounts of wattage saved add up to big savings for the planet.
• Keep appliances clean. Did you know that vacuuming your refrigerator condenser will help it to run less often and cool more efficiently? Keep the dryer clean too so it can dry clothing faster and use less energy.
• Accept a little discomfort. Instead of running the heat and air conditioning to keep yourself at the ideal temperature, let it fluctuate up and down to save energy.
• Reduce energy use during peak hours. 7am to 10pm are peak energy hours for most of the country during most of the year. It’s hard to cut down on energy usage during waking hours, but if you can you’ll save a lot of energy and cut down on your bill too.
• Invest in solar panels. Even a couple of solar panels can really help offset your energy usage. Many utility companies around the United States are taking advantage of government incentives and may be able to install your solar system for free!
• Buy into renewable energy. Many energy companies offer programs where subscribers can buy into renewable energy projects. The electricity from renewables costs a bit more, but by buying in you allow your energy provider to buy into renewable and burn fewer fossil fuels.

There are dozens of ways we can all think of to save a little energy here and there. From riding a bike to eating fresh foods we can help decrease the amount of energy it takes to power our lives.

8. Environmental Degradation

Environmental degradation occurs when human activities change the environment for the worse.

Environmental Degradation Definition

Environmental degradation is the destruction or deterioration of the quality of natural resources and habitats including soil, water, air, and wildlife .

Degradation primarily happens through pollution, over-harvesting, and erosion.

Here are some examples of environmental degradation .

• Strip mining
• Urban sprawl
• Overfishing
• Marine pollution
• Air pollution

Environmental degradation is inevitable because we have to use the land for food production, energy production, and dwellings, but we can do a lot to help preserve the quality of the land.

Environmental Degradation Solutions

There are a number of thing we can do to help reduce the amount of environmental degradation that happens as a result of our own needs and wants.

• Replant native trees and plants . Much environmental degradation occurs because native plants are stripped away for development. Replanting exposed soil helps to replenish minerals, nitrogen, habitats, and stop erosion.
• Curb energy consumption. Again we come back to energy use. The majority of the air pollution in the United States is caused by energy consumption and transportation.
• Plan travel wisely. Instead of making lots of small trips, try to consolidate trips in the car to cut down on air pollution.
• Invest in alternative energy. Alternative energy sources also cause soil degradation because of the raw materials that have to be mined to make them and soil disruption from placement. However, it is much less pollutive to the air than fossil fuels.
• Eat whole foods. Responsible farming and ranching helps to replenish soils through crop rotation and the use of nitrogen-fixing cover crops. However, America’s insatiable appetite for snack foods creates a high demand for irresponsibly grown crops. Eating whole foods is much better for the earth.
• Invest in urban revitalization. If you’re a renter it can be hard to find an urban dwelling. However, if you’re an invester, consider revitalizing downtown industrial areas for housing instead of developing low-density suburban housing.

Humans aren’t responsible for all types of environmental degradation, but we contribute a lot to it. We can also help clean up our habits and use fewer resources that result in habitat destruction.

9. Deforestation

Deforestation happens when trees are stripped away or burned away. It can be human-caused or the result of a natural disaster.

Sometimes humans and nature work together to create deforestation. Examples include when a hydroelectric dam bursts due to catastrophic rainfall, or a volcano like Mt. Saint Helens flattens a forest.

Human-caused deforestation is two-fold. Sometimes managed forests owned by timber companies are stripped and then replanted. This happens for lumber and to create biomass for power plants.

While habitat loss and environmental degradation are heartbreaking, the trees will regrow within a few decades. However, the animals and birds must shift from place to place to survive.

On the other hand, forest fires caused by human activity will deforest an area that may not ever recover. Habitat loss is sometimes permanent .

Deforestation Solutions

The most obvious solution to deforestation is to replant trees in areas that are logged or burned for any reason. Replanting with native species is a must.

The second solution to deforestation is to decrease the demand for paper products and lumber. Choose things that are reusable as much as possible.

The alternative to lumber is steel which creates a different problem because it requires mining and uses non-renewable resources .

However, steel can be recycled forever. One of the benefits of recycling steel is that the recycled steel is just as strong and pure as virgin steel.

So while the recycled steel industry can’t keep up with the need for new steel, as more steel is recycled for construction purposes we should see it gradually relieve some of the need for lumber.

10. Recycling Inefficiencies

The final huge environmental problem that we must solve domestically is our recycling inefficiencies.

Most Americans don’t realize that our recycling system is strained and largely broken because we don’t recycle our trash at home.

The story of US recycling is a long one that’s full of problems, even from the beginning. China used to handle the bulk of our recycling, but it is so polluted that they banned it in 2018.

Now America’s recycling waste is shipped to developing countries like Cambodia, Bangladesh, and Ethiopia where it is piled waiting to be sorted and recycled into usable materials.

The problem is that anywhere from 20 to 70% of our recyclables end up in a landfill overseas or are burned. This is an outrage that has sparked a lot of discussions but it needs to be addressed at home.

Here are the reasons our recycling is not being recycled.

• People are putting contaminated items into recycling bins. Dirty recyclables can cause an entire load of recyclables – several tons – to be dumped in a landfill.
• People include non-recyclables in recycling bins. This wishful recycling is a major cause for discarding entire loads of recyclables. It’s too expensive to go through and sort it all back out, so it all gets put in the dump.
• The United States isn’t processing recyclables. The United States doesn’t have a federal recycling program and has been dependent on other countries to handle our waste. Now they don’t want it, so we’re stuck with it. We have to implement a recycling program and do it ourselves to succeed.
• Recycling is expensive. Cities used to sell their recycling as a type of raw material and make money from it. Now that global market has dried up and cities are having to pay to get rid of recyclables. That means tons of it are going into the landfill instead of being recycled.
• There are too many types of plastic. Plastic is a particular problem because there are so many types and not all are recyclable. Even though there is a number and a recycling symbol on the bottom doesn’t mean it’s accepted for recycling.

All of this is discouraging because those of us who recycle carefully realize that in spite of us our clean, sorted recyclables might still be ending in a landfill.

Recycling Solutions

The keys to our recycling disaster are expensive, and we have to play the long game to win.

• Education. Educate the public about what’s happening to recyclables and why. When people understand why they can’t throw grocery bags or plastic wrap in with clean water bottles they’ll stop doing it.
• Federal Investment. The federal government needs to invest in recycling centers that can turn US recyclable waste into clean, usable materials. It’s an expensive solution but the only one that can turn the situation around long-term.
• Business Investment. One of the major recycling benefits is that businesses can create packaging and goods with recycled materials. This will help to create a circular market for recyclables in the US economy.
• Reduction. The US must turn away from consumerism and focus on sustainability. As long as we buy into the consumerist culture of getting as much as possible, the waste problem will continue to grow.

We can help at home by ensuring that our recyclables are clean and generating less of a need for recycling by decreasing our dependence on single-use items.

It would also be helpful to limit plastic production to only types that are safe to use and can be recycled.

The benefits of recycling clothes and textiles can’t be overstated. Engaging in this circular economy saves money, eliminates fabric waste, and turns fabric into a renewable resource!

Causes of Environmental Problems

The causes of environmental problems usually come back to excess consumption . As the human population expands we are also collectively demanding more resources per person.

Humans want to use more energy, more precious metals, more water, more food, and more luxurious items like fashionable clothing and multiple vehicles.

All of these demands can be met, but only by expending more of the earth’s natural resources. Metals and fossil fuels are non-renewable so as demand increases the price goes up and the supply goes down.

The key to so many of our major environmental problems is to decrease personal consumption.

Why are environmental problems common in developing countries?

Good question and the answer comes back to excess consumption . Many developing countries receive our excess clothing, recyclables, and used goods.

They develop a market around these used goods, but there is simply too much. It ends up in massive waste piles because many of the goods we discard are low-quality and non-recyclable.

Developing countries lack the infrastructure to deal with polluted water, overflowing landfills, and piles of unused recyclables so they stay in the environment creating health and environmental hazards.

One example is electronics recycling. While we all want to reap the benefits of recycling electronics , when they’re sent overseas for recycling the results are dangerous.

“Informal” recyclers are exposed to extremely high levels of neurotoxins and carcinogens as they break down e-waste by hand to recover gold, silver, copper, and other precious metals.

Instead of exposing the poor to these hazardous materials we should be doing the recycling at home and helping to develop a clean recycling industry abroad.

Final Thoughts

We’ve discussed 10 global environmental problems, and most of them center around the demands of the economically developed world.

The problems we face on planet earth can seem overwhelming, but they aren’t. We can solve them beginning with our own buying and consumption habits .

We can become involved in clean-up efforts in our own communities. We can lobby for domestic recycling plants.

We can help educate our own community members about why recycling is important and why it’s vital to do it right.

What do you think about these environmental problems and solutions? Do you have more ideas for how we can help to solve these environmental problems? Let us know in the comments below!

Brainstorming Ways to Solve Environmental Problems? 5 Simple Ways You Can Help

June 1, 2019

Home  /  News  /  Brainstorming Ways to Solve Environmental Problems? 5 Simple Ways You Can Help

We are currently facing the most critical environmental issues in human history. Our climate, planet, lives, and future as a civilization are all at risk. While the magnitude of that thought can be extremely overwhelming, don’t allow yourself to feel helpless, not knowing where to begin. Making small steps and adjustments in your daily routine will give you a sense of success and a yearning to attempt more.

Here are 5 simple ways you can help the environment and spark others to become more environmentally aware.

1. Replace disposable items with reusable

Anything you use and throw away can potentially spend centuries in a landfill. See below for simple adjustments you can make to decrease the amount of disposable items in your daily life.

• Carry your own reusable cup or water bottle
• Use airtight, reusable food containers instead of sandwich bags and plastic wrap
• Pack a waste-free lunch: carry your utensils, cloth napkin, and containers in a reusable lunch bag
• Bring your own bags to the grocery store
• Consider buying bulk containers of your preferred beverages and refilling a reusable bottle, instead of buying individually packaged drinks
• Use rechargeable batteries

2. Pass on paper

We are living in the Digital Era, but think about all the paper products you use in your daily life. These actions still align with reusing and repurposing, though may take a little more time for transition.

• Join a library instead of buying books or buy a Kindle
• Print as little as possible; and if you must, print on both sides
• Wrap gifts in fabric and tie with ribbon; both are reusable and prettier than paper and sticky-tape
• Stop using paper towels and incorporate washable cloths
• Look at labels to make sure you only use FSC-certified wood and paper products
• Cut out products made by palm oil companies that contribute to deforestation in Indonesia and Malaysia

3. Conserve water & electricity

The tips you see below will seem like no-brainers; however, it may take to become more aware of your unconscious habits.

• Turn the sink water off when brushing your teeth
• Water the lawn in the morning or evening; cooler air causes less evaporation
• Switch off anything that uses electricity when not in use (lights, televisions, computers, printers, etc.)
• Unplug devices when possible; even when an appliance is turned off, it may still use power
• Remove chemicals inside of the house; research companies that use plant-derived ingredients for their household cleaning products
• Remove chemicals outside of the house; use eco-friendly pesticides and herbicides that won’t contaminate groundwater
• Consider signing up for a renewable energy producer that uses 100% renewable energy to power homes

4. Support local & environmentally friendly

Here are a few reasons to start buying local:

• Reduces plastic and paper waste
• Boosts cost-efficiency
• Enables bulk purchasing
• Helps support your neighbors
• Retains farmland within the community
• Builds up the local economy
• Uses fewer chemicals for both for growing and transporting

5. Recycle (& then recycle properly)

Implementing recycling habits into your daily life is one of the most effective ways to help lessen landfill waste, conserve natural resources, save habitats, reduce pollution, cut down on energy consumption, and slow down global warming.

• Confirm you are using the proper separation containers for your household per the local recycling services
• Remember to make sure your trash bags are recycled or biodegradable, and always cut up the plastic rings from packs of beer or soda to prevent wildlife from getting caught
• Educate yourself about what can and cannot be recycled, as not all plastic and cardboard is acceptable (like pizza boxes for example, due to the grease) ( click here for a simple 101 )
• Learn how to identify and dispose of hazardous waste properly ( click here to learn more )

Taking the time to simply read this article for ways to solve environmental problems is a step forward to becoming more aware of the needs of your environment. You are now taking action, and every change–big or small–will create an impact.

If you’re already taking action on the suggestions above, see below for additional tips and ideas:

• Add these simple lists to your digital checklist and pick one at a time to tackle. After a week or so, check it off the list and move on to the next. Remember to pat yourself on the back! You just created a change in your lifestyle!
• Find a comfortable compromise for your life. Purchase a pack of affordable, reusable rags and give them a specific purpose. For example, perhaps you always clean your countertops with paper towels; try wiping them down with cloth towels instead.
• Remember to highlight your successes and share them with others! #savetheplanet
• Calculate your environmental footprint to see how much impact just one person has on the world’s resources and adjust accordingly.
• Consider an environmentally-focused career like one of the top four environmental jobs of the future.

Ten solutions to climate change that will actually make a difference

Jun 20, 2022

At this point we need solutions bigger than any one person. But that doesn’t tell the whole story.

There are a lot of differing opinions on whether it's too late to climate change — and, if it's not the best way of going about it. Some say recycling is useless and that individual action means nothing against the larger policy reforms that need to happen. This is, in part, true — although you should absolutely still be recycling. But it doesn’t tell the whole story, and it doesn’t help those who are currently on the frontlines of the climate crisis. Here, we break down 10 solutions to climate change that will actually make a difference — and how you can help make them all a reality.

Stand with the people most affected by climate change

1. shift to renewable energy sources in all key sectors.

The United Nations identified a six-sector solution to climate change, focusing on actions that can be taken by the energy, industry, agriculture, transportation, nature-based solutions, and urban planning. If all of these actions are completed, the UN Environment Programme estimates we could reduce global carbon emissions by 29 to 32 gigatonnes, thereby limiting the global temperature rise to 1.5º C.

One key element of this plan is shifting to renewable energy sources, both at home and at work. “We have the necessary technology to make this reduction by shifting to renewable energy and using less energy,” the UNEP writes of our personal energy consumption (generally, fossil fuels power our homes, keeping the lights on, our rooms warm, and Netflix streaming). But the energy usage of the industrial sector also plays a key role: Addressing issues like methane leaks and switching at large scale to passive or renewable energy-based heating and cooling systems could reduce industrial carbon emissions by 7.3 gigatonnes every year.

2. Reduce food loss and waste and shift to more sustainable diets

There are a few different ways that climate change and hunger go hand-in-hand. Whether it’s kale or Kobe beef, producing food accounts for some measure of greenhouse gasses. In 2021, the Food and Agriculture Organization estimated we consumed more meat than ever before . By 2050 this will, by some estimates, increase greenhouse gas emissions from food production by 60%. Likewise, many farmers use nitrous-based fertilizers to grow more crops, more quickly to meet demand.

It’s important to reduce food waste at every step of the food system . For us as consumers, we can commit to eating what we buy and composting what we don’t get to in time. We can also switch our focus to plant-based and other sustainable diets, supporting farms that use organic fertilizers and making beef and other meat products the exception rather than the rule at the dinner table.

3. Halt deforestation and commit to rebuilding damaged ecosystems

The rapid deforestation of the Earth, especially over the last 60 years, has contributed to climate change, creating “heat islands” out of land that would normally be protected by trees and other flora from overheating. Simply put, this has to stop. There are actions each of us can take as individuals to help halt this—going paperless and buying recycled paper products, planting trees or supporting organizations that do this (like Concern ), and recycling.

But change has to happen at a larger scale here. Illegal logging happens both in the United States and abroad. Last year, world leaders committed to halting this and other harmful practices by 2030 as part of COP26. You can help by holding your own elected leaders to account.

4. Embrace electric vehicles, public transport, and other non-motorized options for getting around

The carbon savings on junking your current car in favor of an electric model are basically nullified if you aren’t seriously in the market for a new vehicle. However, mass adoption of electric vehicles and public transport — along with walking, biking, skating, and scooting — is key to cutting the greenhouse gas emissions from fuel-based motor vehicles.

This is another issue you can raise with elected officials. Earlier this year, for example, you may remember hearing that President Biden had been encouraging the US Postal System to adopt electric vans as part of its new fleet. This didn’t come to pass , but it’s changes like these — changes beyond any one person’s transportation method — that need to happen. You can call on your representatives to support these switchovers for delivery vehicles, cab and taxi fleets, ambulances, and other auto-centric services. Or, if your city or town lacks decent public transportation or enough bike lanes or sidewalks to make those alternatives to driving, lobby for those.

5. Subsidize low-carbon alternatives for urban planning

In tandem with low-carbon alternatives for public transportation, governments need to commit to similar measures with our growing cities. New buildings mean a new opportunity to reward green design methods that help to decrease the strain on urban resources, whether they’re apartments or entertainment venues. (Fun fact: The Stavros Niarchos Cultural Center in Athens runs almost entirely off of solar panels during the bright and sunny summer months. ) In cities like New York, we’ve seen the toll that excessive power use can take through rolling blackouts and brown-outs, especially in the summer months. Changes to public infrastructure that reduce our reliance on the power grid will help to keep the system from becoming untenably overloaded.

6. Strengthen resilience and climate adaptation methods in MAPA communities

So far, we’ve looked at solutions to climate change that can take place within our own homes and communities. However, these only go so far to mitigate the damage that the climate crisis has already inflicted on a large portion of the world. The most affected people and areas (MAPAs) are largely in the Global South. Many are located in low-income countries without the resources or infrastructure to respond and adapt to climate disasters, even as they become more frequent and destructive.

Countries like the United States and organizations responding to the climate crisis must support MAPA communities, particularly the most vulnerable, in developing and carrying out strategies specific to context and designed to bolster resilience where it’s needed most. Often these communities know what needs to be done to mitigate the effects of climate change, and they simply need to be supported with access to additional research and meteorological data, new technologies, and funding.

What we talk about when we talk about resilience

The word “resilience” has taken on new meanings and contexts in recent years, but at Concern it still has a specific definition relating to our emergency and climate response. Here’s what we mean when we use it.

7. Address poverty and other inequalities that increase vulnerability

The tem MAPA can also apply to individuals within a community. Women, disabled people, children, the elderly, people living in poverty, indigenous peoples, and LGBTQIA+ people are among those who are most likely to be hit harder by climate change because of preexisting societal marginalization. This is why it’s critical that they also have a seat at the decision-making table when it comes to solutions to climate change within their own communities. Ending poverty and the other systemic inequalities that give some people greater access to resources than others will help to offset some of the greatest threats posed by the climate crisis.

8. Invest in disaster risk reduction (DRR)

Disaster Risk Reduction (otherwise known as DRR) protects the lives and livelihoods of communities and individuals who are most vulnerable to disasters or emergencies. Whether the crisis is caused by nature or humans (or a combination of both), DRR limits its negative impact on those who stand to lose the most.

We can’t undo much of climate change’s impact so far, but we can help the communities who are hit hardest by these impacts to prepare for and respond to these emergencies once they strike.

9. Commit to fair financing and climate justice

Of course, DRR strategies and other resilience, adaptation, and mitigation practices cost money. Money that the countries most affected by climate change often lack. As part of a global commitment to climate justice , countries with the highest carbon footprints should be making restitution to those countries with lower footprints, countries that tend to be more vulnerable to global warming.

Countries like the United States must increase investments in disaster prevention and DRR strategies, such as early warning and response systems, forecast-based financing mechanisms, and adapted infrastructure. What’s more, these funds need to be made rapidly dispersible and flexible so that when emergency strikes, they can be accessed more quickly. Additional investment to prevent conflicts over the use of natural resources will also help countries facing both fragile political systems and a high risk for climate-related disasters.

RAPID is a funding program that allows Concern to quickly and efficiently deliver aid to people displaced by conflict or natural disaster.

10. Guarantee these changes in the long-term via policy reform

Few of the solutions listed above are not sustainable without policy reform. You can help by encouraging your elected officials to consider the above points, and to support bills that incorporate one or more of these solutions to climate change, many of which are currently being written and shared at the local and national levels.

Smart climate policy will prioritize people over corporations, consider the framework of climate justice — including land and water rights of indigenous peoples and rural communities, address the intersectional effects of climate change on hunger, poverty, and gender equality, and enforce regulatory frameworks and standards that commit people and institutions to honoring these new standards. Bold and aggressive action must be taken if we’re to reach the goal of not exceeding 1.5º C and mitigating the current effects of climate change by 2030. But it’s not a lost cause yet. It’s on all of us to now support those actions that are needed most.

6 global environmental issues and ways you can help

1. loss of biodiversity .

In 2019, the United Nations published a groundbreaking report stating that more than one million animal and plant species are at risk of becoming extinct in the upcoming decades. Conservationists have been urging us to protect wildlife for years, and now it’s a race against the clock. The world needs biodiversity. Birds transport seeds across rainforests, sharks balance ocean food webs, mangroves hold important nutrients in wetlands… without diverse species and their unique ecological roles, our planet would suffer greatly. 

What you can do: 

Habitat loss and fragmentation is one of the fastest growing threats against species’ survival. From shrinking elephant corridors in India to bulldozed koala eucalyptus groves in Australia , animals are losing their habitats at a startling rate. Help make a difference by respecting natural landscapes and participating in habitat restoration projects. Like all environmental issues, we also need large scale government action to help save endangered species. Support international and local wildlife protection legislation like the Endangered Species Act, and vote for candidates who advocate for conservation.  

2. Human-wildlife conflict 

Today’s human-dominated landscapes can make it difficult for animals to find abundant habitat and resources. Conflict — real or perceived — between people and wildlife looks different all around the world. For people in Malawi, conflict may include unexpected encounters with large animals like leopards, crocodiles, and hippos that cause serious injury - sometimes leading to retaliatory killing of wildlife. In India, community members face conflict with elephants who graze on crops and cause great economic loss. Across Canada and the United States, government programs kill thousands of wolves, beavers, bobcats, and bears through unscientific poisoning and cull initiatives. Throughout the COVID-19 pandemic, closed cities and quieter communities led to more accounts of wildlife sightings as animals came out of hiding. In this ever-changing world, it’s important that we understand the role of wildlife and learn how to respect all species so we can better coexist.  

Human wellbeing and wildlife protection are interconnected. When animals are treated with respect and able to play their natural role in the environment, humans benefit greatly. Ecosystems heal, lifestyles improve, eco-tourism thrives, and we get to appreciate the intrinsic beauty of wildlife. 

• In urban areas and neighborhoods, approaches to human-wildlife coexistence can be as simple as using animal-proof trash cans and walking pets on leashes. 
• In rural areas, sustainable measures may include installing fencing around crops, training wildlife rangers, and securing wildlife corridors where animals can safely migrate without human encounters. 

Coexistence is possible and there are countless innovative solutions that promote the wellbeing of animals and humans.   

3. Ocean noise and vessel strikes  

These days, most of us can order an item online with the click of a button—but what comes as a convenience to us is a danger to wildlife. The majority of the world’s products are transported by large cargo ships, and unfortunately, they are threatening the lives of marine animals. Ships and other industrial activity produce sound waves known as ocean noise pollution that create a maze of noise and disorient marine animals. Ocean noise pollution can prevent animals like dolphins and whales from communicating, hunting, and finding mates. In some cases, it can even lead to immense stress and death. Another issue facing marine animals is ship strikes and collisions of all sizes. Blunt trauma from propeller strikes and ship collisions can cause internal injury, sliced fluke tails, and a slow death for whales. For the case of the North Atlantic right whale , ship strikes are pushing the species to extinction. 

• Local consumerism is key to minimizing ocean noise and reliance on ships. Instead of purchasing items online which require shipping and plastic packaging, shop at local stores. 
• If you do have to make an online purchase, skip the fast shipment option and choose consolidated packaging if you have more than one item. 
• Reducing ship speeds is also a critical act for protecting marine mammals from ocean noise pollution and ship strikes. When ships operate at slower speeds, ocean noise reduces and the chance of vessel strikes drops drastically.

4. Plastic pollution 

An estimated eight million tons of plastic end up in our oceans every year , threatening the health of ecosystems, marine animals, and humans. Plastic debris can entangle marine animals , causing deep lacerations, starvation, and strangulation. Turtles are known to consume floating plastic bags (mistaking them for jellyfish) and 90% of all seabirds have consumed plastic. When plastics break down into microplastics, they are even more dangerous. Species lower on the food chain like fish, plankton, and oysters consume microplastics when filtering water. Toxins from the microplastics then get passed through the food web, reaching their way to large marine animals and humans. 

• Choose a day to track all of the disposable plastic that you use from morning to night. 
• After you’ve written a list, research and choose sustainable alternatives made out of material like wood, glass, or natural fibers. 
• Replacement items could include reusable produce bags for bulk shopping, travel utensils to keep in your car, or reusable snack baggies - the list is endless. 
• For times when you do purchase plastic, always recycle and do it correctly. Make sure you wash containers before throwing them in the bin and familiarize yourself with local recycling protocols. 

5. Intensive farming of animals   

Intensive farming—also known as factory farming—involves industrialized facilities utilizing confinement systems with high stocking densities. Not only does intensive farming cause immense suffering to millions of animals, but it also has a devastating environmental impact. The Food and Agriculture Organization report, Livestock's Long Shadow, found that 37% of the world's methane emissions come from factory farming. Untreated animal waste full of highly concentrated chemicals and bacteria is stored in giant manure lagoons that emit gases like carbon dioxide, methane, and ammonia. When overflow occurs from broken infrastructure or rain, the waste leaches into soil and causes dangerous threats to environmental and human health. This includes harmful algae blooms, contamination of drinking water, ammonia pollution, and pathogen outbreaks.  

 What you can do:  

• Reduce your meat consumption by incorporating more vegetarian and vegan meals into your diet. Use it as an opportunity to explore new plant-based ingredients and recipes. 
• Buy local produce and support local farms where animal welfare and environmental impact are prioritized. 
• Educate yourself on the meanings of certifications and labeling , and advocate for better protection for farmed animals through new legislation propositions.   

6. Food waste  

Food waste and loss occurs along every step of food production, from farms to factories, to grocery stores and consumers. During production, waste happens when production exceeds demand, manufacturing damages product, and food spoils during transportation. On the consumer end, food waste occurs mainly from over-purchasing and throwing out blemished produce. The United States Department of Agriculture estimates that 30-40% of food in the United States goes to waste . All food has an ecological footprint. When we waste food, we waste the energy and natural resources that went into production, and contribute to landfills that produce greenhouse gases. 

• Vegetables don’t need to be perfect. As long as the food isn't spoiled, blemishes and imperfections are safe to consume. 
• Remember to take what you need and eat what you take. If you have a habit of over-purchasing food, try to actively buy less or donate to local food banks. 
• Learn how to properly store and freeze food to make it last longer and save money. 
• Consider starting a compost bin where leftover food scraps can turn into nutritious soil for your garden. Don’t have a garden of your own? Donate your compost soil to a nearby farm, urban garden, or school.

Thinking about climate change can be overwhelming. We’ve been aware of its causes for decades now, and all around us, we bear witness to its devastating effects on our communities and ecosystems.

But the good news is that we now know exactly what it will take to win the fight against climate change, and we’re making measurable, meaningful progress. Game-changing developments in clean energy, electric vehicle technology, and energy efficiency are emerging every single day. And countries—including Canada , China , India , and the United States —are coordinating and cooperating at levels never seen before in order to tackle the most pressing issue of our time.

The bottom line: If the causes and effects of our climate crisis are clearer than ever, so are the solutions.

Ending our reliance on fossil fuels

Greater energy efficiency, renewable energy, sustainable transportation, sustainable buildings, better forestry management and sustainable agriculture, conservation-based solutions, industrial solutions, technological solutions, our choices.

The single-most important thing that we can do to combat climate change is to drastically reduce our consumption of fossil fuels . The burning of coal, oil, and natural gas in our buildings, industrial processes, and transportation is responsible for the vast majority of emissions that are warming the planet —more than 75 percent, according to the United Nations. In addition to altering the climate , dirty energy also comes with unacceptable ecological and human health impacts.

We must replace coal, oil, and gas with renewable and efficient energy sources. Thankfully, with each passing year, clean energy is making gains as technology improves and production costs go down. But according to the Intergovernmental Panel on Climate Change's Special Report on Global Warming of 1.5°C , in order to meet the goal of reducing global carbon emissions by at least 45 percent below 2010 levels before 2030—which scientists tell us we must do if we’re to avoid the worst, deadliest impacts of climate change—we must act faster.

There are promising signs. Wind and solar continue to account for ever-larger shares of electricity generation. In 2021, wind and solar generated a record 10 percent of electricity worldwide. And modeling by NRDC has found that wind, solar, hydro, and nuclear could account for as much as 80 percent of U.S. electricity by the end of this decade . (We can also fully realize our clean energy potential if we invest in repairing our aging grid infrastructure and installing new transmission lines.) While this transformation is taking place, automakers—as well as governments—are preparing for a future when the majority of vehicles on the road will produce zero emissions.

Energy efficiency has been referred to as “the first fuel”; after all, the more energy efficient our systems are, the less actual fuel we have to consume, whether rooftop solar energy or gas power. Considered this way, efficiency is our largest energy resource. As the technology harnessing it has advanced over the past 40 years, efficiency has contributed more to the United States’s energy needs than oil, coal, gas, or nuclear power.

What’s more, energy efficiency strategies can be applied across multiple sectors: in our power plants, electrical grids, factories, vehicles, buildings, home appliances, and more. Some of these climate-friendly strategies can be enormously complex, such as helping utility companies adopt performance-based regulation systems , in which they no longer make more money simply by selling more energy but rather by improving the services they provide. Other strategies are extraordinarily simple. For example, weatherproofing buildings, installing cool roofs , replacing boilers and air conditioners with super-efficient heat pumps , and yes, switching out light bulbs from incandescent to LED can all make a big dent in our energy consumption.

Transitioning from fossil fuels to clean energy is the key to winning the fight against climate change. Here are the most common sources of renewable energy —and one source of decidedly nonrenewable energy that often gets included (falsely) in the list.

Solar energy

Solar energy is produced when light from the sun is absorbed by photovoltaic cells and turned directly into electricity. The solar panels that you may have seen on rooftops or at ground level are made up of many of these cells working together. By 2030, at least one in seven U.S. homes is projected to have rooftop solar panels, which emit no greenhouse gases or other pollutants, and which generate electricity year-round (in hot or cold weather) so long as the sun is shining. Solar energy currently accounts for just under 3 percent of the electricity generated in the United States—enough to power 18 million homes —but is growing at a faster rate than any other source. By 2035, it could account for as much as 40 percent of electricity generation. From 2020 through 2026, solar will account for more than half of new electricity generation worldwide.

What to do when the sun doesn’t shine, you might ask. Alongside the boom in solar has been a surge in companion battery storage: More than 93 percent of U.S. battery capacity added in 2021 was paired with solar power plants. Battery storage is key to the clean energy revolution—and adapting to a warming world. Not only are batteries important at night when the sun isn’t out, but on hot days when homes draw a lot of electricity to power air conditioners, battery storage can help manage the energy demand and control the threat of power failures.

Wind energy

Unlike solar panels, which convert the sun’s energy directly into electricity, wind turbines produce electricity more conventionally: wind turns the blades of a turbine, which spin a generator. Currently, wind accounts for just above 9 percent of U.S. electricity generation, but it, like solar, is growing fast as more states and utilities come to recognize its ability to produce 100 percent clean energy at a remarkably low cost. Unsurprisingly, states with plenty of wide-open space—including Kansas , Oklahoma , and Texas —have huge capacity when it comes to wind power, but many analysts believe that some of the greatest potential for wind energy exists just off our coasts. Offshore wind even tends to ramp up in the evenings when home electricity use jumps, and it can produce energy during the rainy and cloudy times when solar energy is less available. Smart planning and protective measures , meanwhile, can ensure we harness the massive promise of offshore wind while limiting or eliminating potential impacts on wildlife.

Geothermal and hydroelectric energy

Along with sunlight and wind, water—under certain conditions—can also be a source of renewable energy. For instance, geothermal energy works by drilling deep underground and pumping extremely hot water up to the earth’s surface, where it is then converted to steam that, once pressurized, spins a generator to create electricity. Hydroelectric energy uses gravity to “pull” water downward through a pipe at high speeds and pressures; the force of this moving water is used to spin a generator’s rotor.

Humans have been harnessing heat energy from below the earth’s surface for eons—just think of the hot springs that provided warmth for the people of ancient Rome. Today’s geothermal plants are considered clean and renewable so long as the water and steam they bring up to the surface is redeposited underground after use. Proper siting of geothermal projects is also important, as recent science has linked some innovative approaches to geothermal to an increased risk of earthquakes.

Hydroelectric plants, when small-scale and carefully managed, represent a safe and renewable source of energy. Larger plants known as mega-dams, however, are highly problematic . Their massive footprint can disrupt the rivers on which people and wildlife depend .

Biomass energy

With very few exceptions, generating electricity through the burning of organic material like wood (sourced largely from pine and hardwood forests in the United States), agricultural products, or animal waste—collectively referred to as biomass —does little to reduce carbon emissions, and in fact, does far more environmental harm than good. Unfortunately, despite numerous studies that have revealed the true toll of this form of bioenergy , some countries continue to buy the biomass industry’s false narrative and subsidize these projects. Attitudes are changing but, given the recent wood pellet boom, there is a lot more work to be done.

Transportation is a top source of greenhouse gases (GHG), so eliminating pollution from the billions of vehicles driving across the planet is essential to achieving net-zero global emissions by 2050, a goal laid out in the 2015 Paris climate agreement .

In 2021, electric vehicles (EVs) accounted for less than 8 percent of vehicle sales globally; by 2035 , however, it’s estimated that they’ll account for more than half of all new sales. Governments around the world aren’t just anticipating an all-electric future; they’re bringing it into fruition by setting goals and binding requirements to phase out the sale of gas-powered internal combustion engine (ICE) vehicles. That year, 2035, is expected to mark a turning point in the adoption of EVs and in the fight against climate change as countries around the world—as well as numerous automakers—have announced goals to phase out gas-powered cars and light trucks. This shift will also benefit our grid: EVs are like a “ battery on wheels ” and have the potential to supply electricity back to the network when demand peaks, helping to prevent blackouts.

It’s also critical that we consider all of the different ways we get around and build sustainability into each of them. By increasing access to public transportation—such as buses, ride-sharing services, subways, and streetcars—as well as embracing congestion pricing , we can cut down on car trips and keep millions of tons of carbon dioxide out of the atmosphere every year. And by encouraging zero-emission forms of transportation, such as walking and biking, we can reduce emissions even more. Boosting these alternate forms of transportation will require more than just talk. They require funding , planning, and the building out of supportive infrastructure by leaders across the local, state, and national levels.

To address the full set of impacts of the transportation sector, we need holistic and community-led solutions around things like land-use policies and the way we move consumer goods. Communities closest to ports , truck corridors, rail yards, and warehouses are exposed to toxic diesel emissions and face a high risk of developing acute and chronic public health diseases. Like all climate solutions, long-lasting change in the transportation sector requires building the power of historically marginalized communities.

The energy used in our buildings—to keep the lights on and appliances running; to warm them and cool them; to cook and to heat water—makes them the single-largest source of carbon pollution in most cities across the United States. Making buildings more energy efficient, by upgrading windows and adding insulation to attics and walls, for example, will bring these numbers down. That’s why it’s all the more important that we raise public awareness of cost- and carbon-saving changes that individuals can make in their homes and workplaces, and make it easier for people to purchase and install energy-efficient technology, such as heat pumps (which can both heat and cool spaces) and certified appliances through programs like Energy Star in the United States or EnerGuide in Canada.

Beyond the measures that can be taken by individuals, we need to see a dedication from private businesses and governments to further building decarbonization , which simply means making buildings more efficient and replacing fossil fuel–burning systems and appliances with clean-powered ones. Policy tools can help get us there, including city and state mandates that all newly constructed homes, offices, and other buildings be outfitted with efficient all-electric systems for heating, cooling, and hot water; requirements that municipalities and states meet the latest and most stringent energy conservation standards when adopting or updating their building codes would also be impactful. Indeed, many places around the world are implementing building performance standards , which require existing buildings to reduce their energy use or carbon emissions over time. Most important, if these changes are going to reach the scale needed, we must invest in the affordable housing sector so that efficient and decarbonized homes are accessible to homeowners and renters of all incomes .

Some of our strongest allies in the fight against climate change are the trees, plants, and soil that store massive amounts of carbon at ground level or underground. Without the aid of these carbon sinks , life on earth would be impossible, as atmospheric temperatures would rise to levels more like those found on Venus.

But whenever we clearcut forests for timber or rip out wetlands for development, we release that climate-warming carbon into the air. Similarly, the widespread overuse of nitrogen-based fertilizers (a fossil fuel product) on cropland and generations of industrial-scale livestock farming practices have led to the release of unprecedented amounts of nitrous oxide and methane, powerful greenhouse gases, into our atmosphere.

We can’t plant new trees fast enough to replace the ones we clearcut in carbon-storing forests like the Canadian boreal or the Amazon rainforest —nor can rows of spindly young pines serve the same function as old-growth trees. We need a combination of responsible forestry policies, international pressure, and changes in consumer behavior to put an end to deforestation practices that not only accelerate climate change but also destroy wildlife habitat and threaten the health and culture of Indigenous communities that live sustainably in these verdant spaces. At the same time, we need to treat our managed landscapes with as much care as we treat wild ones. For instance, adopting practices associated with organic and regenerative agriculture —cover crops, pesticide use reduction, rotational grazing, and compost instead of synthetic fertilizers—will help nurture the soil, yield healthier foods, and pay a climate dividend too.

Intact ecosystems suck up and store vast amounts of carbon: Coastal ecosystems like wetlands and mangroves accumulate and store carbon in their roots; our forests soak up about a third of annual fossil fuel emissions; and freshwater wetlands hold between 20 and 30 percent of all the carbon found in the world’s soil. It’s clear we’re not going to be able to address climate change if we don’t preserve nature.

This is one reason why, along with preserving biodiversity, climate experts are calling on global leaders to fully protect and restore at least 30 percent of land, inland waters, and oceans by 2030 , a strategy endorsed by the Intergovernmental Panel on Climate Change. To help us reach that goal, we must limit industrial impacts on our public lands and waters, continue to protect natural landscapes, support the creation of marine protected areas, uphold bedrock environmental laws, and follow the lead of Indigenous Peoples, many of whom have been faithfully and sustainably stewarding lands and waters for millennia .

Heavy industry—the factories and facilities that produce our goods—is responsible for a quarter of GHG emissions in the United States and 40 percent globally, according to the EPA. Most industrial emissions come from making a small set of carbon-intensive products: basic chemicals, iron and steel, cement, aluminum, glass, and paper. (Industrial plants are also often major sources of air and water pollutants that directly affect human health.)

Complicating matters is the fact that many industrial plants will stay in operation for decades, so emissions goals for 2050 are really just one investment cycle away. Given these long horizons for building and retrofitting industrial sites, starting investments and plans now is critical. What would successfully decarbonized industrial processes look like? They should sharply reduce heavy industry’s climate emissions , as well as local pollution. They should be scalable and widely available in the next decade, especially so that less developed nations can adopt these cleaner processes and grow without increasing emissions. And they should bolster manufacturing in a way that creates good jobs.

Technology alone won’t save us from climate change (especially not some of these risky geoengineering proposals ). But at the same time, we won’t be able to solve the climate crisis without researching and developing things like longer-lasting EV batteries , nonpolluting hydrogen-based solutions , and reliable, safe, and equitable methods for capturing and sequestering carbon . Because, while these tools hold promise, we have to make sure we don’t repeat the mistakes of the past. For instance, we can take actions to reduce local harms from mining lithium (a critical component of electric vehicle batteries), improve recycling opportunities for solar cells, and not use carbon capture as an excuse to pollute. To accelerate research and development, funding is the critical third leg of the stool: Governments must make investing in clean energy technologies a priority and spur innovation through grants, subsidies, tax incentives, and other rewards.

A protester rings a bell in front of P&G’s headquarters in Cincinnati; the company’s toilet paper brand, Charmin, uses wood pulp from virgin trees in Canada's boreal forest.

Finally, it should go without saying that we, as individuals, are key to solving the climate crisis—not just by continuing to lobby our legislators and speak up in our communities but also by taking climate actions in our daily lives . By switching off fossil fuels in our homes and being more mindful of the climate footprint of the food we eat, our shopping habits, how we get around, our use of plastics and fossil fuels, and what businesses we choose to support (or not to support), we can move the needle.

But it’s when we act collectively that real change happens—and we can do even more than cut down on carbon pollution. Communities banding together have fought back fracking , pipelines , and oil drilling in people’s backyards . These local wins aren’t just good news for our global climate but they also protect the right to clean air and clean water for everyone. After all, climate change may be a global crisis but climate action starts in your own hometown .

We have a responsibility to consider the implications of our choices—and to make sure that these choices are actually helping to reduce the burdens of climate change, not merely shifting them somewhere else. It’s important to remember that the impacts of climate change —which intersect with and intensify so many other environmental, economic, and social issues—fall disproportionately on certain communities, namely low-income communities and communities of color. That’s why our leaders have a responsibility to prioritize the needs of these communities when crafting climate policies. If those on the frontlines aren’t a part of conversations around climate solutions, or do not feel the benefits of things like cleaner air and better job opportunities, then we are not addressing the roots of the climate crisis.

Climate change: Seven technology solutions that could help solve crisis

Tuesday 12 October 2021 17:26, UK

Technological advances, particularly the discovery and use of fossil fuels, have contributed to climate change - but they have also allowed humanity to become aware of our impact on the planet and develop techniques to address global warming.

Ahead of Climate After Covid: A Green Recovery? on Sky News on Thursday night, we look at seven innovations which could help humanity avoid the catastrophic damage which a continued increase in global temperatures could cause:

1. Carbon capture

The rising average temperature of the Earth is primarily blamed by scientists on man-made emissions of greenhouse gases that trap radiation in the atmosphere which would otherwise escape into space.

Among the most significant greenhouse gases is carbon dioxide (CO2), concentrations of which have increased by almost 50% since the industrial revolution began.

Innovations being used to reduce CO2 emissions include carbon capture, utilisation, and storage technologies - with the Net Zero Teesside (NZT) project being an interesting example.

NZT aims to capture CO2 produced in industrial processes and power plants and transport these emissions by pipeline to offshore storage sites several kilometres beneath the North Sea.

Sequestered in secure areas deep beneath the sea, this carbon would no longer contribute to the greenhouse effect - and it could even be synthesised into new fuels for transportation systems in the future.

The aim, as the NZT project's name suggests, will be to reduce carbon emissions in a number of carbon-intensive industries in the North East to zero by as early as 2030.

But the scale of the Earth's problem is far more significant than can be solved by the selective decarbonisation of a low number of businesses.

2. Feeding cows seaweed

Another significant greenhouse gas is methane, emissions of which are reaching record levels due to cattle farming.

Agriculture accounted for roughly two-thirds of all methane emissions related to human activities between 2000 and 2017 according to one recent study, with fossil fuels contributing most of the remaining third.

This methane primarily comes from burping cattle, due to how cows digest food - fermenting it in their stomachs where the sugars are converted into simpler molecules that can be absorbed by the body.

Scientists have discovered that a red seaweed which grows in the tropics can reduce methane emissions by 80% in cows when it is added as a supplement to cattle feed.

However, with nearly 1.5 billion head of cattle globally, there is simply not enough of this seaweed currently available to suppress these burps - although perhaps some scientists might be able to reproduce the crucial ingredient which will help keep them down.

3. Delicious insects

While individuals' dietary decisions don't come within the purview of potential technological solutions to climate change, innovative food creation definitely does.

Another interesting way to reduce the methane pollution from cattle farming would be to replace the beef with a substitute made from insects - and this is already taking off in places.

Protein-rich insects such as mealworms can be farmed without the demands on land or water that cattle farming requires - but even if the insects are high in protein there are a number of other crucial nutrients which humans generally only find in meat - including iron.

Some scientific research suggests that a range of insects could provide all of the mineral nutrients which humans need - but of course, even this isn't a quick fix - insect burgers largely remain a novelty item rather than something which can be mass produced and consumed.

4. Climate repair

The Centre for Climate Repair at the University of Cambridge is investigating a number of ideas which would repair the damage being done by human pollution.

Among their ideas are refreezing the poles by brightening the clouds above them, essentially by spraying tiny drops of salt into the sky to assist the clouds in reflecting radiation back into space.

Another suggestion has been "greening" the oceans, essentially fertilising them to encourage the growth of plant matter and algae which could absorb more CO2.

However some research warns that this could cause enormous disruption to the oceans' ecosystems, and potentially wouldn't even then be able to capture enough CO2 to offset emissions.

5. Remote working

As the coronavirus pandemic has shown, many office jobs can be successfully fulfilled from home - potentially offering a route to reduce emissions from transport and office buildings.

Driving to and from work is the largest source of carbon emissions in the developed world.

The technology to support remote working has been rapidly adopted as businesses attempted to manage the impact of COVID-19 on their workers, and governments rushed to lock down their countries and prevent mass deaths.

However remote working may only be an effective method of reducing emissions during the summer.

It turns out that when buildings need to be heated during the winter it is much more efficient to have numerous people in a single building rather than distributed across their own homes, and some research suggests this might even offset the emissions from transportation.

6. Greater use of data centres

A similar logic regarding the heating of individual homes versus office buildings can be applied when it comes to computation.

The advent of computers has increased electricity consumption considerably, but modern data centres are often far more energy efficient than personal computers.

Rather than performing energy-intensive applications on local machines - from crunching complicated numbers through to playing video games - people could begin to offset a considerable amount of energy expenditure by having these applications performed in the cloud.

The big technology companies which specialise in providing cloud computing services - Amazon, Google and Microsoft - are large consumers of renewable energy.

Google and Microsoft have both launched cloud gaming platforms too which don't require gamers to purchase consoles (the production of which also cause emissions) to play them.

But data centres are dependent upon quality internet connections, which themselves can produce emissions, and for many people across the world those connections simply aren't available.

7. Household energy efficiency

The single-most effective technological solution to climate change is going to be reducing energy consumption overall, and nothing is going to do that more than making homes more energy efficient.

The technology to achieve this is already there, with many of the newest products on the market capable of shaving hundreds of pounds off of household bills annually.

The European Union has established an energy labelling scheme that labels appliances for how energy efficient they are, informing consumers about how much it will cost them to run refrigerators and washing machines, as well as other products from light bulbs to televisions.

Energy savings made through design innovations for these household goods might be small individually, but they have the potential to scale and significantly impact energy consumption across the course of a year for a household, and even more significantly across all households in a country.

Across the EU, buildings consume 40% of overall energy and are responsible for 35% of CO2 emissions - although energy consumption per household has dropped over the past 50 years due to efficiency measures.

But according to the independent, statutory body the Committee on Climate Change, homes in the UK are "unfit" at the moment to meet the challenges posed by warming global temperatures and the need to reduce energy consumption. Newer, greener, electronic goods could be a good place to start.

Coronavirus is the greatest global challenge many of us will experience in our lifetimes. But before the pandemic hit, it was climate change that loomed over us as the planet's biggest problem.

So what happens now? How do we deal with both of them at the same time?

New environmental report offers solutions for ‘triple planetary crisis’

Facebook Twitter Print Email

Deadly wildfires, noise pollution and other looming environmental threats could cause widespread ecological damage, and need to be urgently addressed, the UN Environment Programme (UNEP) said in a new report published on Thursday.

“The Frontiers Report identifies and offers solutions to three environmental issues that merit attention and action from governments and the public at large,” said UNEP Executive Director Inger Andersen.

Our 🆕 #Frontiers2022 report highlights emerging issues for people and for planet.It identifies 🔴 urban noise pollution🔴 phenological shifts+ 🔴 wildfires as areas that need urgent attention, and provides solutions to address them: https://t.co/PnBm1pzu5F pic.twitter.com/843z95yzoI UN Environment Programme UNEP

Noise, Blazes and Mismatches: Emerging Issues of Environmental Concern , the sixth report, draws attention to emerging environmental concerns with the potential to wreak regional or global havoc, if not addressed early.

Disrupting natural life cycles

The latest report, released days before the UN Environment Assembly ( UNEA ) resumes, spotlights growing public health threats that are disrupting natural life cycles and having profound ecological consequences worldwide.

“Urban noise pollution, wildfires and phenological shifts – the three topics of this Frontiers Report – are issues that highlight the urgent need to address the triple planetary crisis of climate change, pollution and biodiversity loss,” said Ms. Andersen.

Noise pollution: A raucous killer

Unwanted, prolonged and high-level sounds from road traffic, railways, or leisure activities, impair human health and well-being, according to the report.

Chronic annoyance and sleep disturbance caused by traffic can result in severe heart diseases and metabolic disorders with the very young, and mostly affect the elderly and marginalized communities near busy roads.

Noise pollution also threatens animals by altering the communication and behaviour of various species, including birds, insects, and amphibians .

The report encourages urban planners to prioritize noise reduction by investing in urban infrastructure that creates positive soundscapes such as tree belts, green walls, and more green spaces in cities – also offering diverse health benefits.

London’s Ultra-Low Emission Zone, Berlin’s new cycle lanes on wide roads, and Egypt’s national plan to combat noise, are positive examples that can be harnessed as the world builds back better from COVID.

Plant and animal rhythms

Phenology is the timing of recurring life cycle stages, driven by environmental forces, and how species interacting within an ecosystem, respond to changing conditions.

Plants and animals in terrestrial, aquatic and marine ecosystems use temperature, day length or rainfall as cues for when to bear fruit, migrate or transform in other ways.

However, climate change disrupts these natural rhythms as plants and animals are being pushed out of synch with their natural rhythms, leading to mismatches, such as when plants shift life cycle stages faster than herbivores, the report says.

Meanwhile, local climatic cues that trigger migration for birds may no longer accurately predict conditions at their destination and resting sites along the route.

And in crops, phenological shifts in seasonal variations challenge food production.

The report flags the crucial importance of conservation goals , such as maintaining suitable habitats and ecological connectivity, strengthening the integrity of biological diversity and coordinating international efforts along migratory routes.

Above all, it underscores the importance of reducing CO2 emissions to limit the rate of warming.

Stem wildfires

The report outlined that between 2002 and 2016, an average of 423 million hectares of the Earth’s land surface – about the size of the European Union – burned, projecting that dangerous wildfires will likely become more frequent, intense and longer lasting, including in areas previously unaffected by fires.

Climate change can prompt extreme wildfires, generating lightning that can ignite other fires, far beyond the fire front and creating a so-called hazardous feedback loop.

Long-term effects on human health extend beyond those fighting wildfires, or the evacuated, or those who have lost homes, and exacerbate impacts among those with pre-existing illness, women, children, the elderly and the poor.

At the same time, black carbon and other pollutants generated from wildfires can contaminate water sources, speed up glacier melt, trigger landslides and turn rainforests into carbon sinks .

To address this, the report calls for greater investment in reducing wildfire risks; developing prevention and response management approaches; and refinancing remote sensing capabilities, such as satellites and radar.

Climate Change

The science is clear: the more greenhouse gases in the atmosphere, the warmer it gets. The warmer it gets, the higher our seas, the more intense our storms, the less ice in our Arctic and the more stresses on wildlife. Worse, we're running out of time.

The good news? We know what we need to do and how to do it.

It comes down to switching to cleaner energy like solar, protecting and restoring natural places that can store more carbon, updating our electric grid (which is older than the TV) , and inventing the next great technology.

We put people on the moon. We made supercomputers that fit in your pocket. We are fully capable of doing all of these things, and doing them in time.

Protecting Our Nation's Land & Water

Back in 1977, conservation and recreation made up 2.5% of the federal government's total budget. Today, it's less than 1%. This doesn't make any sense given that our need for healthy land, clean water and open spaces has dramatically increased as our population has grown. 

We’ve had some policy wins (thank you, Great American Outdoors Act) , but our usage demands of lands far outpace the resources coming into them. National and state parks alone host around 1 billion visits each year.

That's hikers, hunters and anglers, but also people going to weddings, reunions and summer camp. Throw in city parks with the baseball games and soccer tournaments and visitor numbers go through the roof. 

Outside of being awe-inspiring, public lands clean our water and our air, and they protect us from coastal storms and heavy rains. They also have a massive positive impact on our economy . Outdoor recreation (often on public lands) generates $887 billion in annual consumer spending, directly supporting 7.6 million jobs.

It’s time to better care for the lands that care for us…but how?

There are plenty of ways to put money back into our lands and waters, if we make the right choices today. There's infrastructure investments that include wetlands and trees, not just levees and seawalls .  There's tax reforms that incentivize private investment in restoring wetlands and forests or donating land for conservation. But, we need to let our elected officials know this is where we want our money to go. 

Take action and speak up for our protecting our lands and waters today. Start with these 5 actions.

Sign up for our monthly Nature News newsletter:

For the past several years, we've seen more frequent, more intense natural disasters ravage communities across the globe. How many “once-in-a-lifetime” disasters must we encounter…in our lifetimes? And what can we do about it?

Because climate change has made these disasters more intense, we have to prevent the worst warming from happening. And, we have to better protect our communities. To do both of those things, we can turn to nature as a part of the solution. Yes, nature!

Healthy forests filter water and can reduce the risk of megafires. Sand dunes, marshes and reefs naturally protect our coasts from the storm surge that arrives with a hurricane. You might be thinking, I see forests and sand dunes all the time, don't we have enough? 

One key word with forests is "healthy." We’ve suppressed natural fires in some forests, making them unhealthy tinderboxes. And while we may have some sandy coastlines, we’ve bulldozed our natural sand dunes and oyster reefs that were our first line of defense for our coasts. 

Nature can bounce back if we give it the chance. Just like we must invest in bridges and roads, we must invest in restoring forests and sand dunes. Nature IS infrastructure. Nature IS investment. Nature IS a solution.

And the best part is while nature reduces risk for us, it also cleans our water and air, gives wildlife a home and gives us great parks to visit. We need to ensure consideration of nature and nature-based solutions in community infrastructure projects. 

Take action and speak up for our natural infrastructure today. To get started, follow our 5 Ways to Speak Up.

Safeguarding Core Environmental Laws

Before Congress passed environmental laws in the 1960s and 1970s, our air was more polluted than ever and rivers had so many pollutants that they actually caught fire.

Lawmakers on both sides of the aisle decided that our health and the health of our natural places were basic values. They worked together to create laws like the Clean Air Act, Clean Water Act, Endangered Species Act and others.

Air and water in this country dramatically improved. Species came back from the brink. And generations of Americans have benefited.

Our country’s successful, bipartisan environmental laws are increasingly under attack. Many proposed changes to the National Environmental Policy Act (NEPA) and Clean Water Act have no basis in science and would erode the laws’ fundamental protections.

Advancing Clean Energy

Humanity has been burning fossil fuels (coal, petroleum and natural gas) at an accelerated rate for around 140 years. Scientists have known for many decades that these forms of energy emit greenhouse gases that are unnaturally warming the planet. In 2018, fossil fuels were responsible for 93% of human-caused carbon emissions in the U.S.

Transitioning to clean energies like wind and solar would make an enormous difference in helping the planet avoid the worst effects of climate change, such as extreme droughts, stronger storms and crippling coastal flooding. And yet, renewables make up less than 10% of the nation's energy mix. 

Over the last decade, the cost of solar has dropped 92% and wind turbines by nearly 50%.  In most parts of the U.S., new renewable energy costs less than coal. The time is right to make the switch.

To quicken and ease this transition, we need to make our power system more reliable by modernizing our century-old electric grid and advancing energy storage. And we need to put those turbines and panels in smart places. We don't need to knock down more forest and prairie; there's enough land already developed to meet our clean energy needs 17 times over.

The benefits of a clean energy shift go way beyond stopping climate change. The shift gives us cleaner air, more consumer choices and more jobs.

Take action and speak up for clean energy today. Start with these 5 actions.

Smart Climate Change Policy : Creating a low-carbon future that benefits everyone.

Modernizing Our Electrical Grid

Our electric grid is the physical network that sends power to our homes and businesses by connecting them in real time to energy plants scattered around the country. This network, much of which is over 75 years old, wasn't built for the technologies our climate-threatened future depends on, like scattered wind turbines and rooftop solar panels. 

It's also not efficient or reliable enough for our needs. It doesn’t take a natural disaster to shut the power off. Currently, something as small as a squirrel can cause an outage that ripples into a larger blackout. 

Technological advances like the internet allow utilities and consumers to relay real time info about energy supply, demand and cost. This is a trove of useful information but its value is held back by infrastructure older than the television. We can build a modernized electrical grid that turns that information into smarter, more efficient choices that let cleaner energy sources shine.

Small changes to how and when we use energy can save us money and make a huge dent in the carbon emissions that cause climate change. 

The U.S. Department of Energy estimates they need an additional $100 billion to fully modernize the grid. That's a lot of money, but those upgrades would save consumers $2 trillion over the next 20 years.

With the current grid causing economic losses of roughly $150 billion a year, there’s never been a better time to start. Let’s bring cutting-edge technology to the grid so it pollutes less, lowers costs for customers and creates jobs.

Take action and speak up for smarter energy today. To get started, follow our 5 Ways to Speak Up. 

We no longer need to choose between abundant energy and a cleaner environment. A renewable energy revolution is happening across the United States. Learn what this means.

To Solve the Environmental Crisis, We Must Foster the Power to Imagine

Our educational system is designed to generate productive workers, not creative thinkers and doers

By Peter Sutoris

Toward the end of my senior year at Dartmouth, I watched my peers line up in front of the Career Services building. Waiting for their interviews for corporate jobs, all seemed to be dressed the same—the men wearing navy jackets, the women dark dresses. I thought back to my first day on campus four years earlier when we all wore different colors and dreamed of different futures. It was as if our education, instead of enhancing our individualities and imaginations, had reduced them to sameness.

It was not a unique scene. All over the world, formal education supplies the economy with workers who will increase productivity. Its purpose is to fuel the economic machine rather than to alter its inner workings. But this machine now threatens our very survival. If the entire world reaches the levels of consumption seen in high-income countries today, we’ll need multiple planet Earths to supply the resources. The absurd idea of infinite growth within a finite territory is at the heart of our economic system.

To keep this machine running, formal education generates ever more efficient “human capital.” Increasing productivity metrics—such as revenue per employee or return on investment—rather than the individuality of students, drive our civilization’s approach to schooling our young people. Whereas the Sustainable Development Goals call for turning education into a force for sustainability, the opposite is often true: the ways Western societies have come to think about education undermine our ability to deal with the environmental crisis. To get through this crisis, we need to cultivate our imagination, not undermine it.

Growing up, none of my schooling fostered my ability to imagine a world different from what I saw around me. As a child in 1990s Slovakia, I had to memorize textbooks word by word. Decades later, as an education researcher, I see children elsewhere going through the same—a chorus of Indian pupils repeating the sentences written by their teacher on the blackboard, a South African child yelled at by the teacher for failing to reproduce exactly the content of the textbook. Rote learning, discouraging individuality and instilling docility in children are still at the root of what it means to be educated across much of the world.

Many experts agree that we need to move away from such approaches to education. But the suppression of children’s imagination doesn’t take place only in underresourced communities or outmoded education systems. The issue is obscured but even more pernicious in “elite” institutions that tout “critical thinking.” Save for a few wise mentors, hardly anyone encouraged me to imagine an alternative future for the world throughout my Ivy League undergraduate years and my Oxbridge graduate years. These institutions want to see their graduates succeed, and success is too often about maintaining current structures—not about reimagining their foundations.

In recent years, we have witnessed efforts towards standardizing curricula across the globe. Such reforms bring Western notions of educational success to the rest of the world. Driven by the OECD’s standardized tests, which rank education systems, countries focus on improving quantifiable outcomes such as literacy and numeracy. Winning the competition for the most efficient educational system today means having the most efficient workforce and growing the national economy faster tomorrow.

Our standardized, metric-driven, “efficient” education systems essentially shape children in the image of artificial intelligence (AI). The perfect “worker,” AI continually improves its own productivity but doesn’t challenge the larger structures within which it operates. It is one of the great paradoxes of our time that we invest so much into building supercomputers while marginalizing the imaginative potential of millions of human brains.

Our focus on technological solutions to our civilization’s challenges is driving our approach to education. More students at British universities are studying science, technology, engineering and mathematics (STEM) than ever before, including a 400 percent increase in enrollment in AI courses over the last 10 years. Compared to STEM, social sciences and humanities are often underfunded and seen as inferior by policy makers and the public alike. But this approach is counterproductive because non-STEM subjects are crucial to fostering our ability to reimagine the world.

We even put our hope in solving the environmental crisis on AI. We use machine learning to optimize energy networks, track land use through satellite imagery and predict extreme weather. But AI, like our other technologies, can only treat the symptoms of the environmental crisis, not the causes. These lie in our arrogance and lack of sensitivity to our impact on the planet. We can’t outsource to computers the solutions to the flaws in our politics and culture that underpin the environmental crisis.

Throughout history, achievers of great change have relied on their imaginations to address fundamental flaws in society. In my country of birth, Czechoslovakia, dissidents against Communism kept their dreams of democracy alive for decades by imagining different futures. In South Africa under apartheid, Nelson Mandela’s followers had to be radical in their imagination to create a vision of a fairer society. Imagining democracy when living under a totalitarian regime isn’t that different from imagining degrowth when living in a world of infinite growth.

The kind of intelligence Nelson Mandela and Václav Havel possessed was not artificial. The ability to reimagine the future and disrupt the status quo remains a distinctly human quality. Unlike AI, children are naturally imaginative and question the premises of society. In my research, I have observed that younger children are often the most radical in imagining different futures; as they get older, their imagination tends to become more generic, mimicking mainstream narratives of technological progress.

As long as our imagination is curtailed, ideas like degrowth or intergenerational justice remain fringe and sound utopian to many. Cultivating imagination means learning from history’s disrupters who made the allegedly impossible palatable. It means moving away from our standardized curricula, quantifiable metrics and authoritarian pedagogies. Instead of dismissing “childish” ideas about the world’s future, it means seeing inspiration in children’s imaginations.

In an education system that celebrates imagination, arts and creativity are as important as math and science. Teachers develop and act on their own pedagogical philosophies. Children define success for themselves. Idealism coexists with pragmatism. Expressing opinions and taking political action are goals of education, not distractions from it. Some of these ideas have already inspired educational projects around the world—such as forest schools in Europe, jeevanshalas (schools of life) in India or Schumacher College in the U.K.—but these are the exceptions.

The environmental crisis is not a crisis of technology or science, it is a crisis of imagination. If we let children be our guides, we might just be able to imagine our way to survival.

• Climate change mitigation involves actions to reduce or prevent greenhouse gas emissions from human activities.
• Mitigation efforts include transitioning to renewable energy sources, enhancing energy efficiency, adopting regenerative agricultural practices and protecting and restoring forests and critical ecosystems.
• Effective mitigation requires a whole-of-society approach and structural transformations to reduce emissions and limit global warming to 1.5°C above pre-industrial levels.
• International cooperation, for example through the Paris Agreement, is crucial in guiding and achieving global and national mitigation goals.
• Mitigation efforts face challenges such as the world's deep-rooted dependency on fossil fuels, the increased demand for new mineral resources and the difficulties in revamping our food systems.
• These challenges also offer opportunities to improve resilience and contribute to sustainable development.

What is climate change mitigation?

Climate change mitigation refers to any action taken by governments, businesses or people to reduce or prevent greenhouse gases, or to enhance carbon sinks that remove them from the atmosphere. These gases trap heat from the sun in our planet’s atmosphere, keeping it warm. 

Since the industrial era began, human activities have led to the release of dangerous levels of greenhouse gases, causing global warming and climate change. However, despite unequivocal research about the impact of our activities on the planet’s climate and growing awareness of the severe danger climate change poses to our societies, greenhouse gas emissions keep rising. If we can slow down the rise in greenhouse gases, we can slow down the pace of climate change and avoid its worst consequences.

Reducing greenhouse gases can be achieved by:

• Shifting away from fossil fuels : Fossil fuels are the biggest source of greenhouse gases, so transitioning to modern renewable energy sources like solar, wind and geothermal power, and advancing sustainable modes of transportation, is crucial.
• Improving energy efficiency : Using less energy overall – in buildings, industries, public and private spaces, energy generation and transmission, and transportation – helps reduce emissions. This can be achieved by using thermal comfort standards, better insulation and energy efficient appliances, and by improving building design, energy transmission systems and vehicles.
• Changing agricultural practices : Certain farming methods release high amounts of methane and nitrous oxide, which are potent greenhouse gases. Regenerative agricultural practices – including enhancing soil health, reducing livestock-related emissions, direct seeding techniques and using cover crops – support mitigation, improve resilience and decrease the cost burden on farmers.
• The sustainable management and conservation of forests : Forests act as carbon sinks , absorbing carbon dioxide and reducing the overall concentration of greenhouse gases in the atmosphere. Measures to reduce deforestation and forest degradation are key for climate mitigation and generate multiple additional benefits such as biodiversity conservation and improved water cycles.
• Restoring and conserving critical ecosystems : In addition to forests, ecosystems such as wetlands, peatlands, and grasslands, as well as coastal biomes such as mangrove forests, also contribute significantly to carbon sequestration, while supporting biodiversity and enhancing climate resilience.
• Creating a supportive environment : Investments, policies and regulations that encourage emission reductions, such as incentives, carbon pricing and limits on emissions from key sectors are crucial to driving climate change mitigation.

What is the 1.5°C goal and why do we need to stick to it?

In 2015, 196 Parties to the UN Climate Convention in Paris adopted the Paris Agreement , a landmark international treaty, aimed at curbing global warming and addressing the effects of climate change. Its core ambition is to cap the rise in global average temperatures to well below 2°C above levels observed prior to the industrial era, while pursuing efforts to limit the increase to 1.5°C.

The 1.5°C goal is extremely important, especially for vulnerable communities already experiencing severe climate change impacts. Limiting warming below 1.5°C will translate into less extreme weather events and sea level rise, less stress on food production and water access, less biodiversity and ecosystem loss, and a lower chance of irreversible climate consequences.

To limit global warming to the critical threshold of 1.5°C, it is imperative for the world to undertake significant mitigation action. This requires a reduction in greenhouse gas emissions by 45 percent before 2030 and achieving net-zero emissions by mid-century.

What are the policy instruments that countries can use to drive mitigation?

Everyone has a role to play in climate change mitigation, from individuals adopting sustainable habits and advocating for change to governments implementing regulations, providing incentives and facilitating investments. The private sector, particularly those businesses and companies responsible for causing high emissions, should take a leading role in innovating, funding and driving climate change mitigation solutions. 

International collaboration and technology transfer is also crucial given the global nature and size of the challenge. As the main platform for international cooperation on climate action, the Paris Agreement has set forth a series of responsibilities and policy tools for its signatories. One of the primary instruments for achieving the goals of the treaty is Nationally Determined Contributions (NDCs) . These are the national climate pledges that each Party is required to develop and update every five years. NDCs articulate how each country will contribute to reducing greenhouse gas emissions and enhance climate resilience.   While NDCs include short- to medium-term targets, long-term low emission development strategies (LT-LEDS) are policy tools under the Paris Agreement through which countries must show how they plan to achieve carbon neutrality by mid-century. These strategies define a long-term vision that gives coherence and direction to shorter-term national climate targets.

At the same time, the call for climate change mitigation has evolved into a call for reparative action, where high-income countries are urged to rectify past and ongoing contributions to the climate crisis. This approach reflects the UN Framework Convention on Climate Change (UNFCCC) which advocates for climate justice, recognizing the unequal historical responsibility for the climate crisis, emphasizing that wealthier countries, having profited from high-emission activities, bear a greater obligation to lead in mitigating these impacts. This includes not only reducing their own emissions, but also supporting vulnerable countries in their transition to low-emission development pathways.

Another critical aspect is ensuring a just transition for workers and communities that depend on the fossil fuel industry and its many connected industries. This process must prioritize social equity and create alternative employment opportunities as part of the shift towards renewable energy and more sustainable practices.

For emerging economies, innovation and advancements in technology have now demonstrated that robust economic growth can be achieved with clean, sustainable energy sources. By integrating renewable energy technologies such as solar, wind and geothermal power into their growth strategies, these economies can reduce their emissions, enhance energy security and create new economic opportunities and jobs. This shift not only contributes to global mitigation efforts but also sets a precedent for sustainable development.

What are some of the challenges slowing down climate change mitigation efforts?

Mitigating climate change is fraught with complexities, including the global economy's deep-rooted dependency on fossil fuels and the accompanying challenge of eliminating fossil fuel subsidies. This reliance – and the vested interests that have a stake in maintaining it – presents a significant barrier to transitioning to sustainable energy sources.

The shift towards decarbonization and renewable energy is driving increased demand for critical minerals such as copper, lithium, nickel, cobalt, and rare earth metals. Since new mining projects can take up to 15 years to yield output, mineral supply chains could become a bottleneck for decarbonization efforts. In addition, these minerals are predominantly found in a few, mostly low-income countries, which could heighten supply chain vulnerabilities and geopolitical tensions.

Furthermore, due to the significant demand for these minerals and the urgency of the energy transition, the scaled-up investment in the sector has the potential to exacerbate environmental degradation, economic and governance risks, and social inequalities, affecting the rights of Indigenous Peoples, local communities, and workers. Addressing these concerns necessitates implementing social and environmental safeguards, embracing circular economy principles, and establishing and enforcing responsible policies and regulations .

Agriculture is currently the largest driver of deforestation worldwide. A transformation in our food systems to reverse the impact that agriculture has on forests and biodiversity is undoubtedly a complex challenge. But it is also an important opportunity. The latest IPCC report highlights that adaptation and mitigation options related to land, water and food offer the greatest potential in responding to the climate crisis. Shifting to regenerative agricultural practices will not only ensure a healthy, fair and stable food supply for the world’s population, but also help to significantly reduce greenhouse gas emissions.

What are some examples of climate change mitigation?

In Mauritius , UNDP, with funding from the Green Climate Fund, has supported the government to install battery energy storage capacity that has enabled 50 MW of intermittent renewable energy to be connected to the grid, helping to avoid 81,000 tonnes of carbon dioxide annually. 

In Indonesia , UNDP has been working with the government for over a decade to support sustainable palm oil production. In 2019, the country adopted a National Action Plan on Sustainable Palm Oil, which was collaboratively developed by government, industry and civil society representatives. The plan increased the adoption of practices to minimize the adverse social and environmental effects of palm oil production and to protect forests. Since 2015, 37 million tonnes of direct greenhouse gas emissions have been avoided and 824,000 hectares of land with high conservation value have been protected.

In Moldova and Paraguay , UNDP has helped set up Green City Labs that are helping build more sustainable cities. This is achieved by implementing urban land use and mobility planning, prioritizing energy efficiency in residential buildings, introducing low-carbon public transport, implementing resource-efficient waste management, and switching to renewable energy sources. 

UNDP has supported the governments of Brazil, Costa Rica, Ecuador and Indonesia to implement results-based payments through the REDD+ (Reducing emissions from deforestation and forest degradation in developing countries) framework. These include payments for environmental services and community forest management programmes that channel international climate finance resources to local actors on the ground, specifically forest communities and Indigenous Peoples. 

UNDP is also supporting small island developing states like the Comoros to invest in renewable energy and sustainable infrastructure. Through the Africa Minigrids Program , solar minigrids will be installed in two priority communities, Grand Comore and Moheli, providing energy access through distributed renewable energy solutions to those hardest to reach.

And in South Africa , a UNDP initative to boost energy efficiency awareness among the general population and improve labelling standards has taken over commercial shopping malls.

What is UNDP’s role in supporting climate change mitigation?

UNDP aims to assist countries with their climate change mitigation efforts, guiding them towards sustainable, low-carbon and climate-resilient development. This support is in line with achieving the Sustainable Development Goals (SDGs), particularly those related to affordable and clean energy (SDG7), sustainable cities and communities (SDG11), and climate action (SDG13). Specifically, UNDP’s offer of support includes developing and improving legislation and policy, standards and regulations, capacity building, knowledge dissemination, and financial mobilization for countries to pilot and scale-up mitigation solutions such as renewable energy projects, energy efficiency initiatives and sustainable land-use practices. 

With financial support from the Global Environment Facility and the Green Climate Fund, UNDP has an active portfolio of 94 climate change mitigation projects in 69 countries. These initiatives are not only aimed at reducing greenhouse gas emissions, but also at contributing to sustainable and resilient development pathways.

10 Environmental Problems and Solutions

If you’re searching for answers to the 10 biggest environmental problems and solutions, you might be concerned with the state of the planet today. If you’re worried, I want you to know that although the world faces major environmental problems, there are solutions. The solutions aren’t simple, and there are no magic bullets, but they exist.

There are also a lot of voices and opinions about environmental issues. So along with basic information about environmental problems and solutions, I also offer different perspectives and further reading so you can form your own opinions. Because there are many possible environmental solutions, and not even the “experts” have all the answers. So I encourage you to keep an open mind to every option. Let’s look for progress, not perfection.

I’ll write more about the UN Sustainable Development Goals below but wanted to mention these goals up-front. If you’re reading this article because you’re concerned about the environment (or maybe you’re feeling stressed or anxious about climate change) learn about the Global Goals first. The Global Goals offer a solid framework for solving environmental problems. Now, on to the 10 biggest environmental problems we face today.

10 environmental problems

These are the 10 biggest environmental problems in no particular order. Climate change is a hot topic right now so I include it first. It’s also first on the list simply because so many of the problems related to climate change are also connected to other environmental problems. Environmental problems like oil spills, deforestation, and poverty need to be solved in and of themselves. But solving these problems indirectly helps solve the problem of climate change.

There are also environmental problems like fluorinated gases that have a large impact on the climate, but not directly on our health or wealth. These problems are extra tricky because they’re expensive to solve and they get little media coverage. That’s why international laws and cooperation are especially important for solving the hardest problems.

Climate change

Climate change is a long-term change in the average weather patterns that have come to define Earth’s local, regional and global climates.” – NASA

Climate change happens when greenhouse gases are released and trapped in the atmosphere, causing the greenhouse effect. The greenhouse effect creates a layer around the earth’s atmosphere that traps heat from the sun, making our atmosphere warmer, similar to a greenhouse.

The following greenhouse gases contribute to climate change.

• Carbon dioxide (CO2) – Carbon dioxide enters the atmosphere when fossil fuels like coal, oil, and natural gas are burned. Carbon dioxide is also released when trees and other plants are burned or cut down and through manufacturing cement. Carbon dioxide made up 81% of man-made greenhouse gas emissions from the United States in 2018 according to the Environmental Protection Agency .
• Methane (CH4) – Methane is released from fossil fuels (natural gas in particular), agriculture (cow farts and manure), and landfills. Methane made up 10% of greenhouse gases in the US in 2018.
• Nitrous oxide (N2O) – Nitrous oxide is emitted from agriculture, fossil fuels, industry, and waste-water treatment. Nitrous oxide made up 7% of greenhouse gas emissions in 2018.
• Fluorinated gases – Fluorinated gases are hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride. They are man-made gases commonly used in refrigerants used for cooling air conditioners and refrigerators. These gases have a high Global Warming Potential and makeup 3% of greenhouse gases emitted in the United States according to the EPA.

Poverty is indirectly linked to environmental problems. When you solve issues related to poverty you also solve environmental problems such as deforestation[cm_simple_footnote id=1], population growth, gender inequality, and climate change.

The world has been making steady progress toward ending extreme poverty for years according to the UN. The COVID-19 crisis has reversed some of the progress. But before the virus, life was better for many people around the world than ever before in history. Now, we need to deal with the crisis and get back to making progress.

Gender inequality

Although gender inequality is also not a direct environmental problem, solving problems like inadequate access to birth control, health services, and education has a positive impact on the economy and environment.

Education lays a foundation for vibrant lives for girls and women, their families, and their communities. It also is one of the most powerful levers available for avoiding emissions by curbing population growth. Women with more years of education have fewer and healthier children, and actively manage their reproductive health. Gender inequality is indirectly linked to environmental problems.” – Drawdown.org

Fluorinated gases used in refrigerants

Fluorinated gases, like the hydrofluorocarbons (HFCs) used in refrigerators and air conditioners, are considered major contributors to climate change according to Drawdown.org. The most commonly used refrigerants have a high Global Warming Potential. The Kigali amendment to the Montreal Protocol offers a timeline for phasing out refrigerants with high Global Warming Potential, but it’s essential for companies and governments to maintain their commitments.

To minimize your personal impact, make sure to properly recycle refrigerators and air conditioning units. If you’re not sure how to recycle an appliance contact your local waste management company.

Fluorinated gases have a potent greenhouse effect and are widely used as refrigerants. Managing leaks and disposal of these chemicals can avoid emissions in buildings and landfills.” – Drawdown

In 2010, the Deepwater Horizon oil rig sank in the Gulf of Mexico, making it one of the most environmentally damaging oil spills in history. The spill covered over 43,300 square miles. It killed and harmed dolphins, sea turtles, fish, and a variety of organisms ( source ).

The environmental problems associated with oil have many layers. Not only does an oil spill kill wildlife and fishing industries, but oil is also a fossil fuel that contributes to climate change. Although oil is a necessary source of energy in every developed and developing country today, it comes with dire environmental problems.

Wasted natural resources

267.8 million tons of municipal solid waste went to landfills instead of being recycled, upcycled, composted, or used for something else in 2017, according to the EPA . That’s a lot of wasted natural resources that originally came from nature, in one form or another. In a circular economy , these natural resources would not be wasted. Instead, they could be upcycled, recycled, or used to regenerate other materials.

Plastic pollution

You’ve probably seen images of marine life drowning in plastic pollution. Maybe you’re aware of the Great Pacific Garbage Patch which is about twice the size of Texas. The people and countries with the highest income generate the most plastic waste. That’s because we can afford to buy more stuff wrapped in plastic.

Plastic pollution is a major environmental problem. Plastic comes from fossil fuels, which we need to phase out, so using less plastic is important. But ultimately solving the problem of plastic pollution may come down to improving waste management technology and creating a more circular economy for plastics.

Food waste[cm_simple_footnote id=2] is a big environmental problem. Up to 40% of food is wasted from farm to fork to landfill according to the National Resources Defense Council . There’s a lot of media coverage about how diet is related to the environment. But the majority of that coverage has to do with how individuals should eat, not how agriculture and waste management services should improve.

Instead of focusing on how individuals should change their eating habits (which is so darned hard) the answers just might lie in improving technology and holding companies to higher environmental standards. This leads me to deforestation, which is closely related to agriculture.

Deforestation

Deforestation is linked to many environmental problems, and the biggest problem is agriculture according to the Food and Agriculture Organization of the United States .

Agri-businesses should meet their commitments to deforestation-free commodity chains and companies that have not made zero deforestation commitments should do so. Commodity investors should adopt business models that are environmentally and socially responsible. These actions will, in many cases, require a revision of current policies and financial incentives. – Food and Agriculture Organization of the United Nations

Ocean acidification

Ocean acidification is one of the main problems associated with climate change. It doesn’t get as much attention as other environmental problems, but it can have a major impact on ocean ecosystems.

The ocean absorbs about 30% of the carbon dioxide (CO 2 ) that is released in the atmosphere. As levels of atmospheric CO 2  increase from human activity such as burning fossil fuels (e.g., car emissions) and changing land use (e.g., deforestation), the amount of carbon dioxide absorbed by the ocean also increases.  When CO 2  is absorbed by seawater, a series of chemical reactions occur resulting in the increased concentration of hydrogen ions. This process has far reaching implications for the ocean and the creatures that live there. – National Oceanic and Atmospheric Administration

10 environmental solutions

Now that you understand the environmental problems we face today, it’s time to understand the potential environmental solutions. I say potential solutions because the cause and effect from environmental problem to environmental solution is complex. There’s a word for this, it’s called dynamic complexity.

The below environmental solutions have the potential to solve different problems within a complex, dynamic, and interconnected system. But there is no magic bullet for environmental problems. So I encourage anyone interested in environmental solutions to think big-picture. Each solution is simply one piece of a giant puzzle. Again, look for progress rather than perfection.

Green innovation

Green innovation may be the most important environmental solution. People around the world are working on new technologies and solutions that could revolutionize the way we look at energy and waste. We haven’t scratched the surface yet on how humanity will solve these problems. But there’s no time to waste, and we need governments and companies to invest in research and development.

One step is to lay the foundation for innovation by drastically increasing government funding for research on clean energy solutions. Right now, the world spends only a few billion dollars a year on researching early-stage ideas for zero-carbon energy. It should be investing two or three times that much.” – Bill Gates

There are several different forms of clean and renewable energy. Solar, wind, and hydro energy are considered renewable energy sources. Nuclear energy, a non-renewable source of energy that contributes little to climate change, is an example of clean energy.

Electrify everything

How to make energy clean and affordable for everyone is not an easy solution to implement. However, the phrase “electrify everything” is a concept that’s fairly easy to understand. Here’s a paragraph that helped me understand how we can truly get clean and affordable energy for everyone on the planet.

“We know, or at least have a pretty good idea, how to get electricity down to zero carbon. There are options: wind, solar, nuclear, hydro, geothermal, and coal or natural gas with carbon capture and sequestration (CCS). There are plenty of disagreements about exactly what mix of those sources will be needed to get us to a carbon-free grid, and what mix of centralized versus distributed resources, and what mix of supply-side versus demand-side solutions — but there’s broad consensus that pathways to fully clean electricity exist.” – The key to tackling climate change: electrify everything by David Roberts for Vox

Carbon taxes

You may have read statements from economists like former Federal Reserve Chairmen Ben Bernanke, Alan Greenspan, Janet Yellen, and Paul Volcker in support of a carbon tax. That’s because pollution and emissions are considered negative externalities.

By correcting a well-known market failure, a carbon tax will send a powerful price signal that harnesses the invisible hand of the marketplace to steer economic actors towards a low-carbon future.” – Statement by economists posted in the Wall Street Journal

Conservation of natural resources

Conserving the natural resources we already have is one important environmental solution. The strategies below help individuals and companies conserve resources:

• Zero waste – Zero-waste is a way for individuals to reduce their own environmental impact by contributing less to landfills by using reusable containers and less plastic.
• Circular economy – “A circular economy is based on the principles of designing out waste and pollution, keeping products and materials in use, and regenerating natural systems,” according to the Ellen MacArthur Foundation.
• Sustainable living – Sustainable living is a general term used to describe lifestyle choices that contribute less to environmental problems.
• Upcycling – Creating a product of higher value from a product or material that would otherwise be thrown away. The clothes and accessories made by ZeroWasteDaniel.com is an excellent example of upcycling.
• Dematerialization – Designing products to use less materials while still creating the same value for the customer. This reduces shipping, natural resources, waste and pollution. A good example of dematerialization is TruEarth’s eco-strips laundry detergent.

Carbon capture and sequestration

Carbon capture and sequestration (CCS) removes carbon dioxide from the atmosphere and stores it in the soil, trees, plants, or underground. CCS is considered one way to mitigate climate change.

The simplest way to capture carbon is through photosynthesis. Trees and plants take atmospheric carbon dioxide and store that carbon in healthy soil and plants using photosynthesis. But there are more high-tech ways to capture and sequester carbon as well. One way is through geoengineering.

Geoengineering is the deliberate large-scale intervention in the Earth’s natural systems to counteract climate change. – Oxford Geoengineering Program

There are also companies that will sequester carbon for you.

Sustainable business and investing

Some businesses, like Patagonia, Interface, and IKEA, have built sustainability and resilience into the core of their companies. Others have fought against sustainability by lawyering up, using loopholes, and lying about the damage their businesses create. If we want environmental solutions, we need to support companies with sustainable business models that support progress.

Improved food production

The environmental problems associated with food production get a lot of attention in the media. Some environmentalists and journalists advocate for plant-based diets and veganism as a solution to the problems associated with food. Changing our eating habits may have a small impact on the environment, but there’s a much larger movement underfoot lead by farmers and entrepreneurs. Below is a shortlist of potential environmental solutions to problems associated with food production and water shortages:

• Regenerative agriculture
• Lab-grown meat
• Plant-based meat
• Verticle farms
• Precision agriculture
• Anaerobic digestion
• Water desalination

Sustainable homes

Our homes use a lot of energy to run our dishwashers, washer and dryers, and HVAC systems. And let’s not forget about all the energy we use charging our computers and watching TV. It adds up. But instead of turning off our devices, it’s possible to build more efficient homes that waste less energy and use cleaner energy sources. Although we have a long way toward making most homes sustainable, here are a few environmental solutions related to homes.

• Net Zero homes
• Home electrification
• Living Buildings
• LEED-certified buildings
• Energy star appliances

15 Biggest Environmental Problems of 2024

While the climate crisis has many factors that play a role in the exacerbation of the environment, some warrant more attention than others. Here are some of the biggest environmental problems of our lifetime, from deforestation and biodiversity loss to food waste and fast fashion.

1. Global Warming From Fossil Fuels

2023 was the hottest year on record , with global average temperatures at 1.46C above pre-industrial levels and 0.13C higher than the eleven-month average for 2016, currently the warmest calendar year on record. The year was marked by six record-breaking months and two record-breaking seasons.

What’s more, carbon dioxide (CO2) levels have never been so high . After being consistently around 280 parts per million (ppm) for almost 6,000 years of human civilisation, CO2 levels in the atmosphere are now well above 420 ppm, more than double what they were before the onset of the Industrial Revolution in the 19th century. According to National Oceanic and Atmospheric Administration (NOAA) Administrator Rick Spinrad, the steady annual increase is a “direct result of human activity,” mainly from the burning of fossil fuels for transportation and electricity generation but also from cement manufacturing, deforestation , and  agriculture .

This is undoubtedly one of the biggest environmental problems of our lifetime: as greenhouse gas emissions blanket the Earth, they trap the sun’s heat, leading to global warming.

Increased emissions of greenhouse gases have led to a rapid and steady increase in global temperatures, which in turn is  causing catastrophic events all over the world – from Australia and the US experiencing some of the most devastating bushfire seasons ever recorded, locusts swarming across parts of Africa, the Middle East and Asia, decimating crops, and a heatwave in Antarctica that saw temperatures rise above 20C for the first time. S cientists are constantly warning that the planet has crossed a series of tipping points that could have catastrophic consequences, such as  advancing permafrost melt in Arctic regions, the Greenland ice sheet melting at an unprecedented rate, accelerating sixth mass extinction , and increasing deforestation in the Amazon rainforest , just to name a few.

The climate crisis is causing tropical storms and other weather events such as hurricanes, heatwaves and flooding to be more intense and frequent than seen before. However, even if all greenhouse gas emissions were halted immediately, global temperatures would continue to rise in the coming years. That is why it is absolutely imperative that we start now to drastically reduce greenhouse gas emissions, invest in renewable energy sources, and phase our fossil fuels as fast as possible.

2. Poor Governance

According to economists like Nicholas Stern, the climate crisis is a result of multiple market failures .

Economists and environmentalists have urged policymakers for years to increase the price of activities that emit greenhouse gases (one of our biggest environmental problems), the lack of which constitutes the largest market failure, for example through carbon taxes, which will stimulate innovations in low-carbon technologies.

To cut emissions quickly and effectively enough, governments must not only massively increase funding for green innovation to bring down the costs of low-carbon energy sources, but they also need to adopt a range of other policies that address each of the other market failures. 

A national carbon tax is currently implemented in 27 countries around the world , including various countries in the EU, Canada, Singapore, Japan, Ukraine and Argentina. However, according to the 2019 OECD Tax Energy Use report, current tax structures are not adequately aligned with the pollution profile of energy sources. For example, the OECD suggests that carbon taxes are not harsh enough on coal production, although it has proved to be effective for the electricity industry. A carbon tax has been effectively implemented in Sweden ; the carbon tax is U$127 per tonne and has reduced emissions by 25% since 1995, while its economy has expanded 75% in the same time period. 

Further, organisations such as the United Nations are not fit to deal with the climate crisis: it was assembled to prevent another world war and is not fit for purpose. Anyway, members of the UN are not mandated to comply with any suggestions or recommendations made by the organisation. For example, the Paris Agreement , a historic deal within the United Nations Framework Convention on Climate Change (UNFCCC), says that countries need to reduce greenhouse gas emissions significantly so that global temperature rise is below 2C by 2100, and ideally under 1.5C. But signing on to it is voluntary, and there are no real repercussions for non-compliance. Further, the issue of equity remains a contentious issue whereby developing countries are allowed to emit more in order to develop to the point where they can develop technologies to emit less, and it allows some countries, such as China, to exploit this. 

3. Food Waste

A third of the food intended for human consumption – around 1.3 billion tons – is wasted or lost. This is enough to feed 3 billion people. Food waste and loss account for approximately one-quarter of greenhouse gas emissions annually ; if it was a country, food waste would be the third-largest emitter  of greenhouse gases, behind China and the US. 

Food waste and loss occurs at different stages in developing and developed countries; in developing countries, 40% of food waste occurs at the post-harvest and processing levels, while in developed countries, 40% of food waste occurs at the retail and consumer levels. 

At the retail level, a shocking amount of food is wasted because of aesthetic reasons; in fact, in the US, more than 50% of all produce thrown away in the US is done so because it is deemed to be “too ugly” to be sold to consumers- this amounts to about 60 million tons of fruits and vegetables. This leads to food insecurity , another one of the biggest environmental problems on the list.

4. Biodiversity Loss

The past 50 years have seen a rapid growth of human consumption, population, global trade and urbanisation, resulting in humanity using more of the Earth’s resources than it can replenish naturally. 

A 2020 WWF report found that the population sizes of mammals, fish, birds, reptiles and amphibians have experienced a decline of an average of 68% between 1970 and 2016. The report attributes this biodiversity loss to a variety of factors, but mainly land-use change, particularly the conversion of habitats, like forests, grasslands and mangroves, into agricultural systems. Animals such as pangolins, sharks and seahorses are significantly affected by the illegal wildlife trade, and pangolins are critically endangered because of it. 

More broadly, a recent analysis has found that the sixth mass extinction of wildlife on Earth is accelerating. More than 500 species of land animals are on the brink of extinction and are likely to be lost within 20 years; the same number were lost over the whole of the last century. The scientists say that without the human destruction of nature, this rate of loss would have taken thousands of years. 

In Antarctica, climate change-triggered melting of sea ice is taking a heavy toll on emperor penguins and could wipe out entire populations by as early as 2100 , according to 2023 research.

5. Plastic Pollution

In 1950, the world produced more than 2 million tons of plastic per year . By 2015, this annual production swelled to 419 million tons and exacerbating plastic waste in the environment. 

A report by science journal, Nature, determined that currently, roughly 14 million tons of plastic make their way into the oceans every year, harming wildlife habitats and the animals that live in them. The research found that if no action is taken, the plastic crisis will grow to 29 million metric tons per year by 2040. If we include microplastics into this, the cumulative amount of plastic in the ocean could reach 600 million tons by 2040.

Shockingly, National Geographic found that 91% of all plastic that has ever been made is not recycled, representing not only one of the biggest environmental problems of our lifetime, but another massive market failure. Considering that plastic takes 400 years to decompose, it will be many generations until it ceases to exist. There’s no telling what the irreversible effects of plastic pollution will have on the environment in the long run.

6. Deforestation

Every hour, forests the size of 300 football fields are cut down. By the year 2030, the planet might have only 10% of its forests; if deforestation isn’t stopped, they could all be gone in less than 100 years. 

The three countries experiencing the highest levels of deforestation are Brazil, the Democratic Republic of Congo and Indonesia. The Amazon, the world’s largest rainforest – spanning 6.9 million square kilometres (2.72 million square miles) and covering around 40% of the South American continent – is also one of the most biologically diverse ecosystems and is home to about three million species of plants and animals . Despite efforts to protect forest land, legal deforestation is still rampant, and about one-third of global tropical deforestation occurs in Brazil’s Amazon forest, amounting to 1.5 million hectares each year . 

Agriculture is the leading cause of deforestation, another one of the biggest environmental problems appearing on this list. Land is cleared to raise livestock or to plant other crops that are sold, such as sugar cane and palm oil . Besides for carbon sequestration, forests help to prevent soil erosion, because the tree roots bind the soil and prevent it from washing away, which also prevents landslides.

7. Air Pollution 

One of the biggest environmental problems today is outdoor air pollution .

Data from the World Health Organization (WHO) shows that an estimated 4.2 to 7 million people die from air pollution worldwide every year and that nine out of 10 people breathe air that contains high levels of pollutants. In Africa, 258,000 people died as a result of outdoor air pollution in 2017, up from 164,000 in 1990, according to UNICEF . Causes of air pollution mostly comes from industrial sources and motor vehicles, as well as emissions from burning biomass and poor air quality due to dust storms. 

According to a 2023 study, air pollution in South Asia – one of the most polluted areas in the world – cuts life expectancy by about 5 years . The study blames a series of factors, including a lack of adequate infrastructure and funding for the high levels of pollution in some countries. Most countries in Asia and Africa, which together contribute about 92.7% of life years lost globally due to air pollution, lack key air quality standards needed to develop adequate policies. Moreover, just 6.8% and 3.7% of governments in the two continents, respectively, provide their citizens with fully open-air quality data.

In Europe, a recent report by the European Environment Agency (EEA) showed that more than half a million people living in the European Union died from health issues directly linked to toxic pollutants exposure in 2021.

8. Melting Ice Caps and Sea Level Rise

The climate crisis is warming the Arctic more than twice as fast as anywhere else on the planet. Today, sea levels are rising more than twice as quickly as they did for most of the 20th century as a result of increasing temperatures on Earth. Seas are now rising an average of 3.2 mm per year globally and they will continue to grow up to about 0.7 metres by the end of this century. In the Arctic, the Greenland Ice Sheet poses the greatest risk for sea levels because melting land ice is the main cause of rising sea levels.

Representing arguably the biggest of the environmental problems, this is made all the more concerning considering that last year’s summer triggered the loss of 60 billion tons of ice from Greenland, enough to raise global sea levels by 2.2mm in just two months . According to satellite data, the Greenland ice sheet lost a record amount of ice in 2019: an average of a million tons per minute throughout the year, one of the biggest environmental problems that has cascading effects. If the entire Greenland ice sheet melts, sea level would rise by six metres .

Meanwhile, the Antarctic continent contributes about 1 millimetre per year to sea level rise, which is one-third of the annual global increase. According to 2023 data, the continent has lost approximately 7.5 trillion tons of ice since 1997 . Additionally, the last fully intact ice shelf in Canada in the Arctic recently collapsed, having lost about 80 square kilometres – or 40% – of its area over a two-day period in late July, according to the Canadian Ice Service .  

Sea level rise will have a devastating impact on those living in coastal regions: according to research and advocacy group Climate Central, sea level rise this century could flood coastal areas that are now home to 340 million to 480 million people , forcing them to migrate to safer areas and contributing to overpopulation and strain of resources in the areas they migrate to. Bangkok (Thailand), Ho Chi Minh City (Vietnam), Manila (Philippines), and Dubai (United Arab Emirates) are among the cities most at risk of sea level rise and flooding.

9. Ocean Acidification

Global temperature rise has not only affected the surface, but it is the main cause of ocean acidification . Our oceans absorb about 30% of carbon dioxide that is released into the Earth’s atmosphere. As higher concentrations of carbon emissions are released thanks to human activities such as burning fossil fuels as well as effects of global climate change such as increased rates of wildfires, so do the amount of carbon dioxide that is absorbed back into the sea. 

The smallest change in the pH scale can have a significant impact on the acidity of the ocean. Ocean acidification has devastating impacts on marine ecosystems and species, its food webs, and provoke irreversible changes in habitat quality . Once pH levels reach too low, marine organisms such as oysters, their shells and skeleton could even start to dissolve. 

However, one of the biggest environmental problems from ocean acidification is coral bleaching and subsequent coral reef loss . This is a phenomenon that occurs when rising ocean temperatures disrupt the symbiotic relationship between the reefs and algae that lives within it, driving away the algae and causing coral reefs to lose their natural vibrant colours. Some scientists have estimated coral reefs are at risk of being completely wiped by 2050. Higher acidity in the ocean would obstruct coral reef systems’ ability to rebuild their exoskeletons and recover from these coral bleaching events. 

Some studies have also found that ocean acidification can be linked as one of the effects of plastic pollution in the ocean. The accumulating bacteria and microorganisms derived from plastic garbage dumped in the ocean to damage marine ecosystems and contribute towards coral bleaching.

10. Agriculture 

Studies have shown that the global food system is responsible for up to one-third of all human-caused greenhouse gas emissions, of which 30% comes from livestock and fisheries. Crop production releases greenhouse gases such as nitrous oxide through the use of fertilisers . 

60% of the world’s agricultural area is dedicated to cattle ranching , although it only makes up 24% of global meat consumption. 

Agriculture not only covers a vast amount of land, but it also consumes a vast amount of freshwater, another one of the biggest environmental problems on this list. While arable lands and grazing pastures cover one-third of Earth’s land surfaces , they consume three-quarters of the world’s limited freshwater resources.

Scientists and environmentalists have continuously warned that we need to rethink our current food system; switching to a more plant-based diet would dramatically reduce the carbon footprint of the conventional agriculture industry.

11. Food and Water Insecurity

Rising temperatures and unsustainable farming practices have resulted in increasing water and food insecurity.

Globally, more than 68 billion tonnes of top-soil is eroded every year at a rate 100 times faster than it can naturally be replenished. Laden with biocides and fertiliser, the soil ends up in waterways where it contaminates drinking water and protected areas downstream. 

Furthermore, exposed and lifeless soil is more vulnerable to wind and water erosion due to lack of root and mycelium systems that hold it together. A key contributor to soil erosion is over-tilling: although it increases productivity in the short-term by mixing in surface nutrients (e.g. fertiliser), tilling is physically destructive to the soil’s structure and in the long-term leads to soil compaction, loss of fertility and surface crust formation that worsens topsoil erosion.

With the global population expected to reach 9 billion people by mid-century, the Food and Agriculture Organization of the United Nations (FAO) projects that global food demand may increase by 70% by 2050 . Around the world, more than 820 million people do not get enough to eat. 

The UN secretary-general António Guterres says, “Unless immediate action is taken, it is increasingly clear that there is an impending global food security emergency that could have long term impacts on hundreds of millions of adults and children.” He urged for countries to rethink their food systems and encouraged more sustainable farming practices. 

In terms of water security, only 3% of the world’s water is freshwater , and two-thirds of that is tucked away in frozen glaciers or otherwise unavailable for our use. As a result, some 1.1 billion people worldwide lack access to water, and a total of 2.7 billion find water scarce for at least one month of the year. By 2025, two-thirds of the world’s population may face water shortages.

12. Fast Fashion and Textile Waste

The global demand for fashion and clothing has risen at an unprecedented rate that the fashion industry now accounts for 10% of global carbon emissions, becoming one of the biggest environmental problems of our time. Fashion alone produces more greenhouse gas emissions than both the aviation and shipping sectors combined , and nearly 20% of global wastewater, or around 93 billion cubic metres from textile dyeing, according to the UN Environment Programme.

What’s more, the world at least generated an estimated 92 million tonnes of textiles waste every year and that number is expected to soar up to 134 million tonnes a year by 2030. Discarded clothing and textile waste, most of which is non-biodegradable, ends up in landfills, while microplastics from clothing materials such as polyester, nylon, polyamide, acrylic and other synthetic materials, is leeched into soil and nearby water sources. Monumental amounts of clothing textile are also dumped in less developed countries as seen with Chile’s Atacama , the driest desert in the world, where at least 39,000 tonnes of textile waste from other nations are left there to rot.

This rapidly growing issue is only exacerbated by the ever-expanding fast fashion business model, in which companies relies on cheap and speedy production of low quality clothing to meet the latest and newest trends. While the United Nations Fashion Industry Charter for Climate Action sees signatory fashion and textile companies to commit to achieving net zero emission by 2050, a majority of businesses around the world have yet to address their roles in climate change.

While these are some of the biggest environmental problems plaguing our planet, there are many more that have not been mentioned, including overfishing, urban sprawl, toxic superfund sites and land use changes. While there are many facets that need to be considered in formulating a response to the crisis, they must be coordinated, practical and far-reaching enough to make enough of a difference.

13. Overfishing

Over three billion people around the world rely on fish as their primary source of protein. About 12% of the world relies upon fisheries in some form or another, with 90% of these being small-scale fishermen – think a small crew in a boat, not a ship, using small nets or even rods and reels and lures not too different from the kind you probably use . Of the 18.9 million fishermen in the world, 90% of them fall under the latter category.

Most people consume approximately twice as much food as they did 50 years ago and there are four times as many people on earth as there were at the close of the 1960s. This is one driver of the 30% of commercially fished waters being classified as being ‘overfished’. This means that the stock of available fishing waters is being depleted faster than it can be replaced.

Overfishing comes with detrimental effects on the environment, including increased algae in the water, destruction of fishing communities, ocean littering as well as extremely high rates of biodiversity loss.

As part of the United Nations’ 17 Sustainable Development Goals (SDG 14) , the UN and FAO are working towards maintaining the proportion of fish stocks within biologically sustainable levels. This, however, requires much stricter regulations of the world’s oceans than the ones already in place. In July 2022, the WTO banned fishing subsidies to reduce global overfishing in a historic deal. Indeed, subsidies for fuel, fishing gear, and building new vessels, only incentivise overfishing and represent thus a huge problem.

14. Cobalt Mining

Cobalt is quickly becoming the defining example of the mineral conundrum at the heart of the renewable energy transition . As a key component of battery materials that power electric vehicles (EVs), cobalt is facing a sustained surge in demand as decarbonisation efforts progress. The  world’s largest cobalt supplier is the Democratic Republic of Congo  (DRC), where it is estimated that up to a fifth of the production is produced through artisanal miners.

Cobalt mining , however, is associated with  dangerous workers’ exploitation and other serious environmental and social issues. The environmental costs of cobalt mining activities are also substantial. Southern regions of the DRC are not only home to cobalt and copper, but also large amounts of uranium. In mining regions, scientists have made note of high radioactivity levels. In addition, mineral mining, similar to other industrial mining efforts, often produces pollution that leaches into neighbouring rivers and water sources. Dust from pulverised rock is known to cause breathing problems for local communities as well.

15. Soil Degradation

Organic matter is a crucial component of soil as it allows it to absorb carbon from the atmosphere. Plants absorb CO2 from the air naturally and effectively through photosynthesis and part of this carbon is stored in the soil as  soil organic carbon (SOC). Healthy soil has a minimum of 3-6% organic matter. However, almost everywhere in the world, the content is much lower than that.

According to the United Nations, about 40% of the planet’s soil is degraded . Soil degradation refers to the loss of organic matter, changes in its structural condition and/or decline in soil fertility and it is often the result of human activities, such as traditional farming practices including the use of toxic chemicals and pollutants. If business as usual continued through 2050, experts project additional degradation of an area almost the size of South America. But there is more to it. If we do not change our reckless practices and step up to preserve soil health, food security for billions of people around the world will be irreversibly compromised, with an estimated 40% less food  expected to be produced in 20 years’ time despite the world’s population projected to reach 9.3 billion people.

Are the Great Lakes the key to solving America’s emissions conundrum?

A single cargo ship can carry enough goods to replace nearly 3,000 semi-trucks—that's why some are calling for a shipping boom in America's famous lakes.

Nearly four decades had passed since the Great Lakes witnessed that unique ritual: the smashing of a bottle of champagne off the bow of a U.S.-flagged cargo ship.

When it finally happened in October 2021 with the launching of the MV Mark W. Barker, a 639-foot-long freighter, in Sturgeon Bay, Wisconsin, it marked a new dawn.

The first bulk carrier to enter service on the Great Lakes for 37 years, the ship can transport goods ranging from salt to wind turbine blades to shipping containers. Its hull design means it can hold 20 percent more cargo than vessels of a similar size. It’s also the first ship sailing the Great Lakes to meet the U.S. Environmental Protection Agency’s tier 4 emissions standards .

“It’s the most capable, most environmentally friendly asset we have,” says Brendan O’Connor, chief operations officer for the Interlake Steamship Company, which operates the MV Mark W. Barker.  

The ship, and others like it, are a critical piece of the climate change puzzle. As the deadlines for meeting the Paris Climate Agreement’s emissions targets   draw ever closer—with the goal for emissions to peak before 2025 and decline 43 percent by 2030—one industry is inducing panic: the transportation world.  

America’s transportation industry is the country’s   leading source of carbon emissions, responsible for a whopping 29 percent . And while privately-owned vehicles make up 58 percent of that, medium- and heavy-duty trucks carrying bulk materials account for 23 percent.

For Hungry Minds

Yet one weapon in the battle against emissions may be sitting in plain sight: the Great Lakes.

Linking Chicago, Detroit, Cleveland, Toronto, Buffalo, and other cities that are home to about 32 million people, Great Lakes shipping could play a significant role in helping the U.S. and Canada dramatically reduce their emissions footprints.

Transporting more goods with fewer vehicles

Today, several ports have projects that could help facilitate that change.

The Port of Cleveland on Lake Erie is set for a $32-million infrastructure upgrade . Farther west on Lake Superior, the Port of Duluth-Superior was recently expanded to handle international container freight . One survey of public and private investments found more than $8.4 billion has been committed to developing Great Lakes maritime infrastructure.

Road freight emits up to 100 times the amount of emissions of ships —a single Great Lakes vessel can carry as much bulk material as 2,800 semi-trucks or 700 rail cars . With gas prices raising trucking costs on average and rail strike threats growing in recent years, Great Lakes shipping could serve as a cleaner, more efficient way to transport many of the critical items America’s economy relies on.  

Still, challenges abound. The two largest Great Lakes cities—Toronto and Chicago— currently both have comparatively small port infrastructure systems.

The Port of Toronto’s economic impact is dwarfed by ports in Montreal and Vancouver, while Chicago’s port has been falling into disrepair for decades. Despite this poor infrastructure, experts say the Port of Chicago has significant potential as a major hub because it is also connected to the Mississippi River by the Illinois Waterway, a network of canals, lakes, and rivers.  

Not a perfect solution

Shipping hasn’t always been a cleaner alternative. In 2021, ships traversing the Great Lakes and St. Lawrence Seaway, the body of water that connects the lakes to the Atlantic Ocean, consumed 500,000 tons of fuel that emitted 1.6 million tons of carbon dioxide, according to one study . That’s the equivalent of around 380,000 cars.

Still, experts say that opportunities for change are growing.

“It’s technically feasible to decarbonize every ship in the fleet,” says Bryan Comer, marine program director at the International Council on Clean Transportation, a Washington, D.C.-based research institute. “The question is: What are the regulatory and economic drivers or incentives to do that?”

Comer says that while there’s potential for electrifying smaller ships such as tugboats, to meet U.S. emissions targets, some larger ships will need new propulsion technologies that replace internal combustion engines with fuel cells that run on ‘green hydrogen,’ an energy resource made from renewable electricity.

“That is going to be the ingredient in all of the fuels that are used,” he says.  

To help meet this transition, the U.S. Department of Energy has made $7 billion available to build up to 10 so-called ‘hydrogen hubs’ across the country .  

“A lot of our efforts are in the scale-up of large-scale production of the clean hydrogen molecules—building out the infrastructure, the storage (and) the delivery,” says Neil Banwart of the Midwest Alliance for Clean Hydrogen , one of seven awardees of the federal funding.

“We certainly do hope that Great Lakes shipping is [a buyer], a use case for this clean hydrogen that we intend to produce.”

Small steps toward big change

In the meantime, Great Lakes ports and shipping companies are working on short-term ways to push the industry closer to net zero.

The Port of Cleveland’s infrastructure update includes an electrification plan and charging stations it hopes will help it fulfill its goal of becoming the first net-zero emissions port on the Great Lakes by 2050.  

The Interlake Steamship Company hopes to cut its emissions footprint by 50 percent in the next decade.

“The engines are going to be the best way for us to move the needle,” says Brendan O’Connor.  

“We’re not quite there yet but in the next two or three years I think we’ll see changes.”

AI’s Trust Problem

• Bhaskar Chakravorti

As AI becomes more powerful, it faces a major trust problem. Consider 12 leading concerns: disinformation, safety and security, the black box problem, ethical concerns, bias, instability, hallucinations in LLMs, unknown unknowns, potential job losses and social inequalities, environmental impact, industry concentration, and state overreach. Each of these issues is complex — and not easy to solve. But there is one consistent approach to addressing the trust gap: training, empowering, and including humans to manage AI tools.

Twelve persistent risks of AI that are driving skepticism.

With tens of billions invested in AI last year and leading players such as OpenAI looking for trillions more, the tech industry is racing to add to the pileup of generative AI models. The goal is to steadily demonstrate better performance and, in doing so, close the gap between what humans can do and what can be accomplished with AI.
