Fossil fuels are wreaking havoc on our environment, and the consequences are more severe than most people realize. The Intergovernmental Panel on Climate Change (IPCC) has found that emissions from fossil fuels are the dominant cause of global warming. In 2018, 89% of global CO2 emissions came from fossil fuels and industry. Fossil fuel pollution reaches into every corner of our lives, from the air we breathe to the water we drink. It is linked to serious health issues, including respiratory problems, cardiovascular disease, and cancer, and is responsible for one in five deaths worldwide. With the cost of clean energy alternatives decreasing and their efficiency increasing, it is time to upgrade to cleaner alternatives to protect our planet for future generations.

What You'll Learn
Fossil fuels produce hazardous air pollutants
Fossil fuels are a major source of hazardous air pollutants, wreaking havoc on both the environment and human health. The combustion of fossil fuels releases a range of harmful substances, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury. These pollutants contribute to respiratory issues, cardiovascular disease, and cancer, with communities located near industrial sites experiencing higher rates of health complications.
Nitrogen oxides, a common byproduct of burning fossil fuels, play a significant role in the formation of smog and acid rain. Acid rain, in turn, causes eutrophication, which harms aquatic ecosystems by lowering oxygen levels and endangering aquatic organisms. Fossil fuel pollution also affects the land, contaminating crops and forests and leading to water pollution. Oil spills, a frequent occurrence, devastate marine ecosystems, destroy habitats, and erode shorelines.
The impact of fossil fuel pollution extends beyond the environment, with social and economic repercussions. Communities of color and low-income communities are disproportionately affected by fossil fuel pollution, experiencing higher exposure to particulate matter pollution. This inequality is evident in areas like "Cancer Alley" in Louisiana, where the cancer risk is nearly 50 times higher than the national average due to the proximity to chemical plants.
Furthermore, the advertising campaigns of fossil fuel companies often obscure the true extent of their environmental impact. While promoting cleaner natural gas, companies like BP continue to allocate the majority of their expenditure to oil and gas. This greenwashing misleads the public and hinders the transition to renewable energy sources, which have become more accessible and affordable.
To address the harmful effects of fossil fuel pollution, a global shift towards clean energy is imperative. Many countries have already set ambitious clean energy targets, recognizing the urgency of reducing emissions and mitigating the devastating consequences of fossil fuel pollution on our planet and public health.

Drilling and mining operations generate toxic wastewater
Fossil fuels have significant environmental externalities, including air and water pollution. Drilling and mining operations, in particular, generate enormous volumes of wastewater, which can be contaminated with heavy metals, radioactive materials, and other pollutants.
Water pollution from mining activities can have severe environmental and health consequences. For instance, mining can deplete surface and groundwater supplies, damaging or destroying streamside habitats far from the mine site. In Nevada, the Humboldt River is being drained to support gold mining operations, and the extraction of groundwater from the Santa Cruz River Basin in Southern Arizona for copper mining is causing the river to dry up.
Another major water quality concern related to mining is the formation of acid rock drainage (ARD), which results from the reaction of water and oxygen with sulfide minerals in mined or exposed rock. ARD leads to acidic waters that mobilize toxic metals, sulfates, and other dissolved solids, rendering water unsafe for human consumption and degrading aquatic habitats.
Similarly, drilling operations for fossil fuels produce large volumes of wastewater, which can be toxic. Each fracking well, for example, uses between 1.5 million and 16 million gallons of water, and the resulting wastewater often contains substances like arsenic, lead, chlorine, and mercury that can contaminate groundwater and drinking water sources.
To mitigate the environmental and health impacts of drilling and mining operations, various methods and regulations have been developed. These include locating mine wastes in areas with limited water resources, isolating mine wastes with liners and caps, implementing water management practices, and treating wastewater using reverse osmosis, aeration, or clarification systems.
While these measures aim to reduce the generation of toxic wastewater, the fact remains that drilling and mining operations for fossil fuels inherently carry a risk of water pollution that can have lasting effects on ecosystems and human communities.

Burning fossil fuels contributes to smog and acid rain
Fossil fuels are wreaking havoc on our environment, and the use of dirty fossil fuel energy directly causes a lot of the environmental damage we see today. When fossil fuels are burned, they release harmful air pollutants, including nitrogen oxides, sulfur dioxide, carbon monoxide, and particulate matter. These pollutants contribute to the formation of smog and acid rain, which have detrimental effects on both human health and the environment.
Smog is a type of air pollution that reduces visibility and is often associated with urban areas. It is formed when nitrogen oxides and volatile organic compounds react in the atmosphere, creating ground-level ozone and fine particles that can be inhaled. Smog can irritate the eyes, nose, and throat, leading to respiratory issues such as coughing, wheezing, and difficulty breathing. It also exacerbates existing respiratory and cardiovascular conditions, particularly in vulnerable populations such as children, the elderly, and individuals with pre-existing health problems.
Acid rain is another significant consequence of burning fossil fuels. Acid rain occurs when sulfur dioxide and nitrogen oxides are emitted into the atmosphere and combine with water vapor and other chemical components to form acidic compounds. These compounds then fall back to the Earth's surface through wet or dry deposition, causing environmental harm. Acid rain can have detrimental effects on aquatic ecosystems, such as lakes, streams, and rivers, by increasing their acidity and lowering oxygen levels. This, in turn, can harm fish and other aquatic life. Additionally, acid rain can damage vegetation, buildings, and other structures, contributing to corrosion and degradation over time.
The burning of fossil fuels, particularly coal, is a major contributor to the formation of acid rain. Coal has the highest carbon content and is the most carbon-intensive fossil fuel when burned. The extraction and combustion of coal release a significant amount of sulfur dioxide and nitrogen oxides into the atmosphere, which are the key components of acid rain. Other fossil fuels, such as oil and natural gas, also contribute to acid rain formation through their extraction, transportation, and refining processes, which can lead to oil spills and the release of additional pollutants.
The environmental and health impacts of burning fossil fuels extend beyond smog and acid rain. Fossil fuel pollution is responsible for one in five deaths globally, with 350,000 premature deaths in the United States alone attributed to fossil fuel-related pollution in 2018. Additionally, the release of carbon dioxide and other greenhouse gases from burning fossil fuels contributes to climate change, leading to global warming, rising sea levels, and more frequent extreme weather events.

Oil spills harm wildlife and destroy habitats
Fossil fuels are indeed harmful to the environment and human health. They are responsible for air pollution, water pollution, and plastic pollution. The extraction, transportation, and refining of fossil fuels can lead to oil spills, which are particularly harmful to wildlife and ecosystems.
Oil spills can have devastating effects on marine and coastal wildlife, causing both immediate and long-term harm. The magnitude of the harm caused varies depending on the type of oil spilled, the amount of exposure, and the life stage of the affected organisms. Some of the most vulnerable creatures include marine mammals, seabirds, sea otters, sea turtles, manatees, dolphins, and whales.
Immediate physical harm includes skin irritation, immune system alterations, reproductive or developmental damage, and liver disease. Inhalation of volatile chemicals released by oil floating on the surface can lead to respiratory inflammation, irritation, emphysema, or pneumonia. Oil spills can also cause behavioural changes in animals, such as relocation of home ranges and increased foraging time.
The synthetic materials used by response teams to clean up oil spills can also influence the magnitude of the harm caused. While "dispersants" can reduce exposure to toxic materials, they may also increase the harmful effects on bird feathers, making it difficult for birds to stay warm and potentially leading to hypothermia. Dispersants can also cause oil particles to reach deeper into the water column, affecting benthic animals in deeper waters.
In addition to the harm caused to wildlife, oil spills can also destroy habitats. They can erode shorelines and impact sensitive organisms and habitats such as mangroves and coral reefs. Oil that remains on beaches for extended periods can harm terrestrial animals such as snails, clams, and other land-dwelling creatures. The effects of an oil spill can be long-lasting, and the ability of an ecosystem to recover depends on the resilience of the affected species.

Fossil fuel pollution disproportionately affects communities of colour and low-income communities
Fossil fuels produce hazardous air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury, all of which are harmful to the environment and human health. Globally, fossil fuel pollution is responsible for one in five deaths. In the United States, 350,000 premature deaths in 2018 were attributed to fossil fuel-related pollution.
The environmental and health impacts of fossil fuels disproportionately harm communities of color and low-income communities. Black, Asian, Hispanic, Latino, and Indigenous Americans are exposed to significantly more particulate matter pollution than they produce. In a predominantly Black and low-income area of Louisiana known as "Cancer Alley," the cancer risk is nearly 50 times higher than the national average due to 150 nearby chemical plants.
Many components of the fossil fuel supply chain and infrastructure in the United States are disproportionately located in communities of color and low-income neighborhoods, creating inequitable landscapes of environmental health risks. Historically redlined neighborhoods have nearly twice the density of oil and gas wells than otherwise similar non-redlined neighborhoods. Drilling and operating oil and gas wells worsen air pollution and are associated with increased risks of health problems, including respiratory disease, cardiovascular disease, depression, and poor birth outcomes.
The Biden administration's Justice40 Initiative is a step towards addressing these disparities, requiring that at least 40% of investments from federal programs in clean energy, transit, affordable housing, workforce development, and remediation of legacy pollution benefit "environmental justice communities." Community-driven accountability structures that track the socioeconomic and health effects of these investments are critical to advancing health equity and protecting vulnerable communities.
