Fossil fuels are non-renewable energy sources that took millions of years to form. They are used to generate power, in transportation, and for energy. The continuous extraction and consumption of fossil fuels deplete Earth's reserves. The burning of fossil fuels like coal, oil, and gas releases carbon pollution, which causes climate change. In 2019, fossil fuels accounted for 74% of US greenhouse gas emissions. The extraction, refining, and burning of fossil fuels have significant environmental impacts, including air pollution, water pollution, and health risks. Fossil fuel companies are spending billions to increase climate pollution, despite warnings from scientists. The transition to clean, renewable energy sources is urgent and necessary to address the planetary crisis caused by the fossil fuel industry.

Fossil fuels cause climate change
Fossil fuels are formed from the decomposition of carbon-based organisms that died and were buried millions of years ago. They create carbon-rich deposits that are extracted and burned for energy. Coal, oil, and gas are the three primary types of fossil fuels. Coal is a solid fossil fuel that comes in four main varieties: lignite, sub-bituminous, bituminous, and anthracite. Oil, or petroleum, is a liquid fossil fuel formed from ancient marine organisms. Natural gas is another fossil fuel that falls under the broader category of gas.
The combustion of these fossil fuels releases large amounts of carbon dioxide (CO2) and other greenhouse gases, such as methane, into the Earth's atmosphere. These gases trap heat, contributing to the greenhouse effect and global warming. The Intergovernmental Panel on Climate Change (IPCC) has identified emissions from fossil fuels as the dominant cause of global warming. In 2023, emissions from fossil fuels reached a record high, with a 1.1% increase compared to 2022 levels. This trend is impeding progress toward limiting climate change.
The consequences of climate change driven by fossil fuel emissions are far-reaching. Rising global temperatures lead to altered weather patterns, more frequent and intense extreme weather events, and ecological disruptions. For example, warmer ocean temperatures fuel destructive cyclones, hurricanes, and typhoons, causing deaths, economic losses, and community destruction. Climate change is also linked to rising sea levels, ocean acidification, biodiversity loss, species extinction, and water scarcity. These impacts pose significant risks to human communities, ecosystems, and biodiversity.
In addition to climate change, the extraction, refining, and burning of fossil fuels have other detrimental effects. Air pollution from fossil fuels contributes to respiratory issues, cardiovascular diseases, asthma, and premature deaths. Globally, one in five deaths is attributed to fossil fuel pollution. Fossil fuel extraction methods, such as mountaintop removal mining and strip mining, can also lead to environmental destruction, habitat loss, and oil spills. Furthermore, the continuous extraction and unsustainable consumption of fossil fuels deplete Earth's finite reserves, leading to increased extraction costs and more intrusive and environmentally damaging methods.

They are finite resources
Fossil fuels are finite resources that took millions of years to form. The continuous extraction and consumption of these resources at an unsustainable rate are depleting the Earth’s fossil fuel reserves. As these reserves diminish, the cost and difficulty of extraction increase, leading to environmental damage from more extensive and intrusive extraction methods. For example, strip mining, a common method for extracting coal, removes entire layers of soil and rock to access coal deposits, taking a significant toll on landscapes and ecosystems.
The development and refinement of processes like fracking have helped make the United States the world’s top producer and consumer of gas since 2009. Fracking is a technique used to extract gas that is too difficult or expensive to access via regular drilling. As fossil fuels become more challenging to extract, we can expect to see more intensive methods like fracking, which can have detrimental environmental consequences.
The extraction and transportation of fossil fuels often involve destructive practices, such as mountaintop removal mining and deforemation. Oil spills, which can have devastating impacts on marine life and local communities, are another consequence of fossil fuel extraction, transportation, and refining. The largest oil spill in history, the 2010 BP Deepwater Horizon spill, released 134 million gallons of oil into the Gulf of Mexico, resulting in 11 human deaths and countless deaths of birds, turtles, fish, marine mammals, and plants. It cost BP $65 billion in penalties and cleanup costs.
The finite nature of fossil fuels and the environmental damage caused by their extraction highlight the urgency of transitioning to renewable energy sources. With the right policies in place, we can make significant progress toward a clean energy future, reducing our reliance on finite fossil fuel reserves.

They cause air pollution
Fossil fuels are made from decomposed plants and animals and are a finite resource. The continuous extraction and combustion of fossil fuels introduce harmful pollutants into the air. Burning fossil fuels releases greenhouse gases, such as carbon dioxide, that contribute to climate change and global warming. The combustion process emits carbon dioxide into the atmosphere, where it acts as a heat-trapping gas. As a result of the increasing rate of air pollutants, the air is becoming more harmful to breathe, and the climate is changing.
The excessive burning of fossil fuels has increased the rate of carbon emissions, which has, in turn, increased the amount of air pollution. This has led to an increase in global temperatures, causing rising sea levels, altered weather patterns, and more frequent and severe extreme weather events. Fossil fuel pollution is responsible for one in five deaths globally. In the United States alone, 350,000 premature deaths in 2018 were attributed to fossil fuel-related pollution.
The combustion of fossil fuels generates a significant amount of air pollution. Fossil fuels produce hazardous air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury. These pollutants are harmful to both the environment and human health. Vulnerable populations, such as children, the elderly, and individuals with pre-existing health conditions, are at the greatest risk. Exposure to air pollutants emitted by burning fossil fuels can lead to respiratory issues, cardiovascular diseases, asthma, and even premature death.
In addition to the health impacts, air pollution from fossil fuels can also cause acid rain, eutrophication, damage to crops and forests, and harm to wildlife. The extraction, refining, and burning of natural gas can also have environmental impacts, despite being considered a cleaner-burning fossil fuel compared to coal and oil. Methane, a potent greenhouse gas released during the extraction, production, and transportation of natural gas, contributes to climate change.

They have health impacts
Fossil fuels have significant health impacts. Burning fossil fuels emits greenhouse gases, such as carbon dioxide, which contribute to climate change and global warming. This, in turn, leads to health issues such as respiratory illnesses, cardiovascular diseases, and asthma. Vulnerable populations, including children, the elderly, and those with pre-existing health conditions, are at the greatest risk.
The combustion process of fossil fuels releases harmful air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury. These pollutants contribute to air pollution, which can cause multiple health issues. Globally, fossil fuel pollution is responsible for one in five deaths. In the United States alone, 350,000 premature deaths in 2018 were attributed to fossil fuel-related pollution. The health impacts of fossil fuel-generated electricity in the United States are estimated to cost up to $886.5 billion annually.
The extraction and transportation of fossil fuels also have health consequences. Oil spills, for example, can harm communities and wildlife, and destroy habitats. The 2010 BP Deepwater Horizon spill in the Gulf of Mexico released 134 million gallons of oil, killing 11 people and countless animals, and costing BP $65 billion in penalties and cleanup costs. Additionally, fracking, a controversial method of extraction, has been linked to air and water pollution, with each fracking well using between 1.5 million and 16 million gallons of water and producing toxic wastewater.
The health impacts of fossil fuels disproportionately affect communities of color and low-income communities. Black and Hispanic Americans are exposed to significantly higher levels of particulate matter pollution than the average population. In a predominantly Black and low-income area of Louisiana, known as "Cancer Alley," the cancer risk is nearly 50 times the national average due to the high number of nearby chemical plants and oil refineries.
Furthermore, the burning of fossil fuels contributes to ocean acidification, which has health implications. The ocean absorbs a significant portion of carbon dioxide emissions, leading to a 30% increase in ocean acidity since the Industrial Revolution. This change in ocean chemistry affects the ability of marine organisms to form shells and coral skeletons, impacting food chains and coastal communities that depend on marine resources.

They cause environmental destruction
Fossil fuels are non-renewable resources that took millions of years to form. The extraction, refining, and burning of fossil fuels have severe environmental impacts. The burning of fossil fuels releases greenhouse gases such as carbon dioxide, nitrous oxide, and methane, which trap heat in the Earth's atmosphere, contributing to climate change and global warming. The combustion process emits carbon dioxide, which acts as a heat-trapping gas, contributing to the greenhouse effect and global warming. The increase in global temperatures caused by greenhouse gas emissions leads to rising sea levels, altered weather patterns, and more frequent and intense extreme weather events, including wildfires, hurricanes, wind storms, flooding, and droughts. These impacts pose risks to human communities, ecosystems, and biodiversity.
The extraction and transportation of fossil fuels often involve destructive practices, such as mountaintop removal mining, strip mining, and deforestation. Strip mining, which accounts for about two-thirds of coal sourced in the US, removes entire layers of soil and rock to access coal deposits. The unearthing, processing, and movement of underground oil, gas, and coal deposits take a significant toll on landscapes and ecosystems. Fossil fuel companies lease vast stretches of land for infrastructure, such as wells, pipelines, access roads, and waste storage facilities, disrupting natural habitats.
Oil spills, a common occurrence during fossil fuel extraction, transportation, and refining, have devastating consequences for communities, wildlife, and the environment. The 2010 BP Deepwater Horizon oil spill in the Gulf of Mexico, for example, resulted in the loss of human and countless animal lives and incurred billions of dollars in penalties and cleanup costs. Oil spills also destroy habitats, erode shorelines, and lead to beach, park, and fishery closures.
The burning of fossil fuels emits hazardous air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury. These pollutants contribute to air pollution, acid rain, eutrophication, damage to crops and forests, and harm to wildlife. Poor air quality can cause respiratory diseases and other health issues such as asthma, cancer, and heart disease. Globally, fossil fuel pollution is responsible for one in five deaths, disproportionately affecting vulnerable communities, including children, the elderly, and individuals with pre-existing health conditions.
