Fossil fuels are bad for the planet and humanity. The burning of fossil fuels releases greenhouse gases, such as carbon dioxide, which trap heat in the Earth's atmosphere and contribute to climate change. In 2019, fossil fuels accounted for 74% of US greenhouse gas emissions. The extraction and transportation of fossil fuels also cause environmental destruction, including deforestation and the destruction of wildlife habitats. The combustion of fossil fuels also causes air pollution, which contributed to 1.2 million deaths in 2020 alone. Fossil fuels are finite resources that took millions of years to form, and the continuous extraction and consumption of these resources at an unsustainable rate deplete the Earth's fossil fuel reserves.

Fossil fuels cause climate change, resulting in extreme weather events
Fossil fuels are the dominant cause of climate change, which is leading to more frequent and severe extreme weather events. Fossil fuels, including coal, oil, and natural gas, are non-renewable sources of energy formed from the decomposition of carbon-based organisms that died millions of years ago. These fossil fuels are extracted and burned for energy, creating carbon-rich deposits that release large amounts of carbon dioxide and other greenhouse gases into the atmosphere.
In 2018, 89% of global CO2 emissions came from fossil fuels and industry, with coal being the largest contributor, responsible for over 0.3°C of the 1°C increase in global average temperatures. Oil is also a significant contributor, releasing approximately a third of the world's total carbon emissions. Natural gas, while promoted as a cleaner alternative, is still a fossil fuel and accounts for a fifth of the world's carbon emissions.
When fossil fuels are burned, they emit greenhouse gases such as carbon dioxide, which trap heat in the Earth's atmosphere, leading to global warming and climate change. As a result of this warming, extreme weather events are becoming more frequent and intense. This includes heatwaves, droughts, floods, wildfires, hurricanes, windstorms, and destructive storm surges, all of which can lead to disasters costing billions of dollars.
The impacts of climate change due to fossil fuel emissions are expected to worsen, with rising global temperatures leading to more frequent and severe extreme weather events. Climate science clearly attributes these changes to the emissions from the largest fossil fuel companies, and only by reducing the supply and use of fossil fuels can we limit the rise in global temperatures and mitigate these worsening impacts.

They are a finite resource, formed over millions of years
Fossil fuels are non-renewable resources, meaning they draw on finite reserves that will eventually run out. They are formed from dead organic material, such as plants and animals, that accumulated and were buried under rock and sediment over hundreds of millions of years. The organic matter was transformed by intense pressure and heat into the concentrated forms of carbon we utilise as coal, oil, and natural gas. This slow formation process means fossil fuels are non-renewable in any practical human timeframe.
The continuous extraction and consumption of fossil fuels deplete the Earth's reserves. As these reserves diminish, the cost and difficulty of extraction increase, leading to more extensive and intrusive methods that cause environmental damage. Oil reservoirs and gas basins will likely eventually deplete, and while technology helps utilise remaining resources, it does not make fossil fuels renewable. There are limits to how far technology can stretch non-renewable reserves, and as these resources become scarcer, their costs will rise.
Unlike finite fossil fuels, renewable energy sources can be replenished within practical human timescales. Sources like solar, wind, hydropower, geothermal, and biomass tap into effectively infinite energy flows that are continuously renewed. For example, solar energy comes from the sun, wind energy from atmospheric currents, and hydropower from the endless water cycle. Biomass energy comes from plants that can be replanted in relatively short timescales.
The transition to renewable energy sources is inevitable as fossil fuel supplies decline. However, this transition must accelerate to avoid severe shortages, price spikes, and environmental damage. Fossil fuels are tightly woven into global economies, powering industries and energy infrastructure for over 150 years. Despite the challenges, the shift to renewables is necessary to address the environmental and climate change concerns associated with finite fossil fuels.

Extraction and transportation damage ecosystems and wildlife habitats
The extraction and transportation of fossil fuels often involve destructive practices, such as mountaintop removal mining, strip mining, and deforestation. These activities cause habitat destruction, soil erosion, biodiversity loss, and ecosystem disruption, harming both wildlife and plant species. For example, strip mining uproots and pollutes entire ecosystems, while coal mining operations wash toxic runoff into streams, rivers, and lakes, endangering aquatic life.
Extraction can also lead to the eviction of people from their homes and the destruction of the cultural identity of communities, particularly Indigenous peoples, as most of the remaining fossil fuels are situated on their land. In addition, the extraction process can result in death threats, attacks, arrests, and even deaths for those who peacefully protest fossil fuels or defend their land.
The transportation of fossil fuels, such as oil, via supertanker, train, truck, or pipeline, also poses risks of accidental spills and leaks, which can have devastating and long-term effects on marine and terrestrial habitats, killing plants, animals, and aquatic organisms, and contaminating drinking water sources. Oil spills jeopardize entire freshwater or ocean ecosystems and can result in beach, park, and fishery closures. The largest oil spill in history, the 2010 BP Deepwater Horizon spill, released 134 million gallons of oil into the Gulf of Mexico, causing the deaths of numerous birds, turtles, fish, marine mammals, and plants, and costing BP $65 billion in penalties and cleanup costs.
Furthermore, the extraction and transportation of fossil fuels contribute to air pollution, releasing harmful pollutants such as nitrogen oxides, sulfur dioxide, and particulate matter, which have negative respiratory health impacts for both humans and wildlife. These emissions also contribute to the formation of smog and acid rain, affecting the quality of the air, land, and water.

Burning fossil fuels releases hazardous air pollutants, causing health issues
Burning fossil fuels releases a range of hazardous air pollutants, which have severe impacts on both the environment and human health. These air pollutants include sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury. When released into the atmosphere, these pollutants contribute to the formation of smog and acid rain, which can cause respiratory issues, cardiovascular diseases, and other respiratory illnesses. Vulnerable populations, such as children, the elderly, and those with pre-existing health conditions, are at the greatest risk of experiencing health issues due to air pollution.
Nitrogen oxides, a common emission from burning fossil fuels, are deposited back onto the land and wash into nearby water bodies, causing eutrophication. This process involves excessive nutrients being introduced into aquatic ecosystems, which can harm them by lowering oxygen levels. Additionally, the burning of fossil fuels, particularly coal, is a significant source of global anthropogenic mercury emissions. Mercury emissions can contaminate land and ocean ecosystems, posing risks to both wildlife and human populations.
The combustion of fossil fuels also contributes to climate change, which has wide-ranging impacts on the environment and human health. Fossil fuels are a dominant cause of global warming, with emissions from their combustion accounting for 74% of US greenhouse gas emissions in 2019. The continuous extraction and consumption of fossil fuels deplete the Earth's finite reserves, formed over millions of years. As reserves diminish, the cost and difficulty of extraction increase, leading to more extensive and environmentally damaging methods.
The transition away from fossil fuels is essential to mitigate climate change, reduce pollution, and protect human health. Renewable energy sources such as solar, wind, and hydroelectric power offer cleaner and more sustainable alternatives. However, despite commitments to reduce carbon emissions, such as the Paris Agreement, the production and advertising of fossil fuel products persist, requiring more urgent action to address the negative consequences of burning fossil fuels.

Their use disproportionately affects marginalised communities
Fossil fuels have been at the heart of interconnected crises, including public health, racial injustice, and climate change. The negative impacts of fossil fuels disproportionately affect marginalized communities, particularly communities of colour and low-income communities. This phenomenon has been termed "fossil fuel racism" or "fossil fuel apartheid".
The fossil fuel industry has been complicit in environmental racism, where the costs of pollution and environmental degradation are externalized onto communities of colour. This has resulted in the creation of "sacrifice zones", where marginalized communities bear the brunt of the harmful effects of fossil fuel use. These communities are disproportionately exposed to toxic air and water pollution, as well as the health risks associated with climate change, such as rising sea levels, droughts, heat waves, and intense hurricanes.
In the United States, the historical practice of redlining has contributed to the disproportionate impact on communities of colour. Redlining involved grading and mapping neighbourhoods according to perceived investment risks, with low-income, immigrant, or Black residents often deemed "hazardous" or "declining". As a result, these neighbourhoods have higher densities of oil and gas wells, pipelines, refineries, and other fossil fuel infrastructure, leading to increased air and water pollution and associated health risks for residents.
Additionally, the transition away from fossil fuels can also disproportionately affect marginalized communities. Without proper policies and support, fossil fuel workers and communities that rely heavily on the industry may face economic hardships and job losses. Therefore, it is crucial to implement a just transition that addresses the needs of these communities and includes them in climate policy-making and implementation.
To address these injustices, there have been calls for a phase-out of fossil fuels and a shift towards more integrative approaches to policy design. The Biden Administration's Justice40 Initiative aims to deliver at least 40% of the benefits of federal climate and clean energy investments to "disadvantaged communities" that are marginalized, underserved, and overburdened by pollution. This initiative, along with the Inflation Reduction Act, aims to address the disproportionate impacts of fossil fuels on marginalized communities and promote a more equitable future.
