Oil spills and water pollution
Oil spills can occur during the extraction, transportation, or refining of fossil fuels, and their impacts can be long-lasting and challenging to mitigate. Even with advancements in oil spill science, cleanup efforts can never remove 100% of the spilled oil, and careless cleanup strategies can inadvertently cause additional harm to sensitive habitats. For example, in the aftermath of the Exxon Valdez oil spill in 1989, it was discovered that the use of high-pressure, hot-water hoses during beach cleanup operations caused more damage than the oil itself.
Water pollution from fossil fuel extraction also extends beyond oil spills. Fracking, a common extraction method, utilizes a mixture of water, chemicals, and sand, pumped at high pressure to fracture rock and release oil or gas. This process generates enormous amounts of wastewater, which often contains toxic substances like arsenic, lead, chlorine, and mercury. This wastewater can contaminate groundwater and drinking water sources, posing risks to both human health and the environment. The contamination of drinking water sources has been linked to cancer, birth defects, and liver damage, with disproportionate impacts on low-income communities and communities of color.
Furthermore, the infrastructure and development associated with fossil fuel extraction can also contribute to water pollution. The construction of roads, facilities, and drilling sites can destroy natural habitats and disrupt wildlife. The heavy equipment and intense activity in extraction areas can lead to soil erosion and the release of toxic substances into nearby water bodies. Additionally, the burning of fossil fuels releases nitrogen oxides and ammonia, which can be deposited back onto land and eventually wash into water bodies, contributing to eutrophication and the creation of oxygen-deprived aquatic zones.

Air pollution and smog
The extraction and burning of fossil fuels have a significant impact on the environment and human health. Fossil fuels, including coal, oil, and natural gas, are the main sources of energy worldwide, accounting for about 79% of total US primary energy production in 2022 and 80% of the world's energy supply. However, their use comes at a cost to the environment and human health, known as externalities. These externalities include air pollution, which can lead to smog and respiratory issues.
When fossil fuels are burned, they release a cocktail of pollutants into the atmosphere, including greenhouse gases such as carbon dioxide (CO2) and nitrous oxide (N2O). These gases trap heat in the Earth's atmosphere, leading to global warming and climate change. The burning of fossil fuels is the primary cause of current climate change, and the effects are far-reaching, impacting both human and environmental health. The average global temperature has already increased by 1°C, and it passed the critical 1.5°C milestone for the first time in 2024. This warming has consequences such as rising sea levels, extreme weather events, biodiversity loss, species extinction, food scarcity, and worsening health for millions worldwide.
Airborne nitrogen pollution is a significant contributor to air pollution from fossil fuels. Nitrogen is essential for plant and animal life, but human activities, such as burning fossil fuels, can upset the natural balance. The combustion of fossil fuels releases nitrogen oxides, which contribute to smog formation and acid rain. Smog, a mixture of smoke and fog, is a visible form of air pollution that reduces visibility and can have detrimental effects on human health. It is a complex mixture of solid particles and gases, including nitrogen oxides and volatile organic compounds, which react in the atmosphere to form fine particles and ground-level ozone, both of which are harmful to human health.
In addition to nitrogen oxides, the burning of fossil fuels emits other hazardous air pollutants, including sulfur dioxide, particulate matter, carbon monoxide, and mercury. These pollutants contribute to respiratory issues and have been linked to various health problems, including asthma, respiratory illness, behavioural development issues in children, and even cancer and heart disease. Globally, fossil fuel pollution is responsible for one in five deaths, with 350,000 premature deaths attributed to it in the United States alone in 2018. The impacts of air pollution disproportionately affect low-income communities and communities of color, with Black and Hispanic Americans exposed to significantly higher levels of particulate matter pollution.
To combat air pollution and smog caused by fossil fuels, a transition to cleaner and renewable energy sources is necessary. The cost of solar and wind energy has decreased significantly in recent years, making it more accessible for countries to adopt cleaner energy alternatives. Additionally, individuals can play a role in reducing air pollution by conserving energy, such as by turning off electrical equipment when not in use and opting for energy-efficient products. While governments and organizations have made commitments to reduce carbon emissions, such as the Paris Agreement, more action is needed to address the impact of fossil fuel extraction and combustion on air pollution and smog.

Climate change and global warming
The burning of fossil fuels—coal, oil, and natural gas—emits greenhouse gases such as carbon dioxide (CO2) and nitrous oxide (N2O) that trap heat in the Earth's atmosphere and contribute to climate change and global warming. Fossil fuels accounted for 74% of US greenhouse gas emissions in 2019, with nearly 25% coming from fossil fuels extracted from public lands. The Intergovernmental Panel on Climate Change (IPCC) warns that fossil fuel emissions must be halved within 11 years to limit global warming to 1.5°C above pre-industrial levels. However, we are currently on track to produce more than double the amount of coal, oil, and gas by 2030 than we can burn to stay within this limit.
The extraction, transportation, and refining of fossil fuels can also directly contribute to global warming through oil spills and other environmental impacts. Oil spills harm communities and wildlife, destroy habitats, erode shorelines, and result in beach, park, and fishery closures. Additionally, the burning of fossil fuels releases carcinogenic ultra-fine particles and aromatic hydrocarbons, contributing to air pollution and causing health issues such as asthma, cancer, heart disease, and premature death. Globally, fossil fuel pollution is responsible for one in five deaths, with 350,000 premature deaths attributed to fossil fuel-related pollution in the United States in 2018 alone.
The effects of global warming driven by fossil fuel usage are already being felt around the world. The Arctic has warmed at twice the global average rate, with temperatures rising by 0.6°C every decade since 1978. The world is now 1°C warmer than pre-industrial times, and the frequency and intensity of extreme weather events such as wildfires, hurricanes, wind storms, flooding, and droughts have increased, resulting in economic losses and threatening coastal communities with sea level rise.
While there is a general consensus that burning fossil fuels contributes to global warming, the exact mechanisms are still being debated. Some scientists argue that thermal emissions, rather than solely CO₂ levels, play a more significant role in raising global temperatures. The extraction of fossil fuels may also contribute to warming by removing the insulating effect they provide between the Earth's core and the surface. As underground reservoirs of fossil fuels are drained and replaced with water, a less effective insulator, more heat from the Earth's interior can escape to the surface, contributing to global warming.
To address global warming and climate change, a transition to renewable energy sources and improved energy efficiency is necessary. While fossil fuel companies have advertised their commitment to low-carbon energy, their actions often do not align with their statements. For example, BP's advertising focused on clean energy while more than 96% of its annual expenditure remained on oil and gas. Regulatory actions, such as banning fossil fuel advertising without health warnings, and public advocacy for progressive climate policies are crucial steps towards mitigating the impacts of fossil fuel extraction and use on global warming.

Human health and cancer risks
The extraction and use of fossil fuels have significant detrimental effects on human health. Burning fossil fuels releases greenhouse gases, such as carbon dioxide, which contribute to climate change and global warming. This, in turn, leads to more frequent and intense climate shocks, such as wildfires and heat waves, which pose challenges for lung cancer patients and can negatively impact patient health and healthcare delivery.
The combustion of fossil fuels also emits toxic air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, mercury, benzene, and formaldehyde. These pollutants are linked to a range of respiratory ailments, such as asthma and bronchitis, and increase the risk of cardiovascular and pulmonary diseases, as well as cancer. Poor air quality has also been associated with infant mortality, damage to the nervous system and brain, and potential contributions to psychiatric disorders and diabetes.
In addition, the health impacts of air pollution disproportionately affect certain communities. For example, Black and Hispanic Americans are exposed to significantly higher levels of particulate matter pollution than the national average, and in "Cancer Alley," a predominantly Black and low-income area of Louisiana, the cancer risk is nearly 50 times higher than the national average due to the high number of nearby chemical plants and oil refineries. Asian Americans, African Americans, and Latinos in certain regions of the US are also exposed to substantially more air pollution from vehicles.
Furthermore, the extraction processes of fracking and drilling have been associated with water pollution and the contamination of drinking water sources. Fracking fluids and drilling wastewater can contain toxic substances, such as arsenic, lead, chlorine, mercury, heavy metals, and radioactive materials, which can leak into waterways and contaminate groundwater and drinking water. These pollutants have been linked not only to cancer but also to birth defects and neurological damage.
The transition to cleaner energy sources and the reduction in the use of solid fuels have helped decrease indoor air pollution. However, ambient air pollution, particularly in urban areas, continues to rise, emphasizing the urgent need to address the health risks associated with fossil fuel extraction and combustion.

Habitat destruction and biodiversity loss
Fossil fuel extraction has a significant impact on the environment, and one of the most pressing issues is habitat destruction and biodiversity loss. The construction of infrastructure for extraction, such as roads, facilities, drilling sites, pipelines, and mining operations, often results in the irreversible destruction of large areas of wilderness and wildlife habitats. This destruction leads to the loss of crucial habitats for many species, reducing their available living space and access to resources. As habitats are destroyed, species face increased competition for limited resources and become more vulnerable to extinction.
One example of this is the impact of natural gas field activity on the migration of pronghorn antelope and mule deer in Wyoming. These species have to navigate past well pads and compressor stations, and their remaining habitat is further diminished by bulldozing. This disruption to their migration patterns and available resources could ultimately have major impacts on the abundance of these herds.
Deforestation for oil palm plantations also contributes to habitat destruction and biodiversity loss. Clearing land for these plantations removes crucial habitats for wildlife and plant species and can lead to soil erosion. Additionally, the extraction and transportation of fossil fuels can result in deforestation and the removal of more vegetation, further exacerbating the loss of biodiversity.
Oil spills and leaks during extraction, transportation, or refining can also have devastating effects on marine life and coastal ecosystems. Oil spills coat the ocean surface, contaminating habitats and poisoning or suffocating marine mammals, fish, birds, and other organisms. They also disrupt food chains and damage sensitive coastal ecosystems, such as coral reefs, mangroves, and salt marshes.
