What You'll Learn
Less air pollution, fewer health issues
Fossil fuels are a leading contributor to air pollution, which is one of the most significant threats to human health worldwide. Burning fossil fuels releases nitrogen oxides, ammonia, sulphur dioxide, ozone, soot, and other harmful pollutants into the atmosphere. These emissions contribute to the formation of smog and acid rain, which have detrimental effects on both human health and the environment.
Air pollution from fossil fuels has been linked to a range of health issues, including respiratory illnesses such as asthma, cardiovascular diseases, and cancer. The combustion of fossil fuels produces ultra-fine particles and aromatic hydrocarbons, which are carcinogenic. 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 alone in 2018. The health impacts of fossil fuel pollution disproportionately affect vulnerable communities, including low-income communities and communities of colour. For example, 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.
Children are also particularly vulnerable to the health impacts of air pollution from fossil fuels. Toxic air pollutants and carbon dioxide emissions from fossil fuel combustion can impair cognitive and behavioural development, leading to disorders, mental health problems, and respiratory illnesses. Additionally, climate change caused by fossil fuels exacerbates these health risks for children, increasing the prevalence of heat-related diseases, malnutrition, infectious diseases, and physical and psychological trauma.
Transitioning to renewable and sustainable energy sources is essential to reducing air pollution and improving human health. By investing in clean energy technologies and infrastructure, we can significantly reduce emissions and mitigate climate change. This will lead to immediate and long-term health benefits, including reduced cases of respiratory and cardiovascular diseases, improved cognitive development, and fewer premature deaths. Additionally, reducing our reliance on fossil fuels will decrease the risk of oil spills and environmental disasters, further protecting human health and the planet.
Overall, decreasing the use of fossil fuels is crucial for improving air quality and reducing the burden of health issues associated with air pollution. By transitioning to renewable energy sources, we can create a healthier and more sustainable future for all, especially for vulnerable communities and children who are disproportionately affected by the detrimental impacts of fossil fuel pollution.

Less money spent on fossil fuel subsidies
Fossil fuels are one of the dirtiest energy sources on the planet, and the leading cause of climate change pollution. In 2022, about $7 trillion was spent on fossil fuels globally, including explicit subsidies, tax breaks, and environmental damage costs. The United States, for example, provides billions of dollars in subsidies to the fossil fuel sector annually, and Europe provides around 55 billion euros. These subsidies are intended to protect consumers by keeping prices low, but they come at a significant cost.
Firstly, fossil fuel subsidies have sizable fiscal consequences, often leading to higher taxes, more borrowing, or lower spending in other areas. This can hinder economic growth and negatively impact social spending, reductions in inefficient taxes, and productive investments. Fossil fuel subsidies also contribute to climate change and premature deaths from air pollution. The production and use of fossil fuels release toxins such as mercury and arsenic, and the transportation of fossil fuels, such as oil, poses risks of spills that severely harm the environment and human life.
Secondly, removing fossil fuel subsidies would reduce energy security concerns related to volatile fossil fuel supplies. As conventional petroleum oil becomes scarcer and more expensive, the push to develop even dirtier fuels, such as tar sands and oil shale, increases. These alternative fuels have even more detrimental effects on the environment, contributing to the destruction of ecosystems and an increase in climate change pollutants.
Lastly, reducing fossil fuel subsidies would free up resources to invest in renewable energy sources, such as solar and wind power. Renewable energy technologies are becoming increasingly cost-competitive, with over 90% of new renewable projects now cheaper than fossil fuel alternatives. Investing in renewable energy would not only reduce pollution and climate impacts but also improve energy security and create new jobs in the clean energy sector.
In conclusion, less money spent on fossil fuel subsidies would have multiple benefits for humans. It would reduce fiscal and environmental costs, improve energy security, and promote the development of cleaner and more sustainable energy sources. These changes would ultimately contribute to a healthier and more prosperous future for humanity.

Less climate change, fewer climate refugees
Fossil fuels are a leading contributor to climate change, so reducing their use will help to mitigate the worst impacts of a warming planet. Climate change increases the risks of extreme weather events, such as storms, floods, wildfires, heatwaves, and droughts, making them more unpredictable, frequent, and intense. It also causes rising sea levels, which, alongside droughts and changes in rainfall patterns, can destroy crops, kill livestock, and lead to food scarcity. These impacts can force people to migrate, either within their own countries or across borders, in search of food, water, and land.
The burning of fossil fuels releases carbon dioxide (CO2) and other pollutants, including sulfur dioxide, ozone, nitrogen oxides, and soot. These emissions trap heat in the Earth's atmosphere, causing global warming and resulting in higher temperatures. Warmer temperatures further exacerbate the impacts of climate change, such as food insecurity, water scarcity, and biodiversity loss.
By transitioning from fossil fuels to renewable energy sources like wind, solar, and hydropower, we can significantly reduce emissions and slow down climate change. This transition will help protect vulnerable communities from the devastating impacts of climate change, reducing the need for displacement and mitigating the risks associated with extreme weather events.
For example, the National Wildlife Federation in the United States has successfully advocated for a reduction in the number of acres of public land available for oil shale and tar sands extraction by two-thirds. This conservation effort will help protect wildlife, water resources, and local communities from the detrimental effects of fossil fuel extraction and the associated pollution.
Additionally, renewable energy sources can provide cheap electricity, improve air quality, and boost economic growth. By investing in renewable energy infrastructure and technology, we can create a more resilient and sustainable future, reducing the risks associated with climate change and ensuring a safer environment for all.

Less risk of oil spills
Less fossil fuel production means less risk of oil spills, which have detrimental impacts on the environment and human life. Oil spills can occur during the extraction, transportation, and refining of fossil fuels. For example, the 2010 BP Deepwater Horizon oil spill in the Gulf of Mexico released 134 million gallons of oil, killing 11 people and numerous birds, turtles, fish, marine mammals, and plants. The event also cost BP $65 billion in penalties and cleanup costs. Oil spills can harm sea creatures, ruin beaches, and make seafood unsafe to eat. They can also lead to beach, park, and fishery closures, as well as cause economic losses for industries dependent on these natural resources.
Oil, a fossil fuel, is often transported by pipes, ships, trucks, or trains, all of which carry the risk of accidents and spills. Oil spills can also occur during the extraction and refining processes. Reducing the production of fossil fuels means there will be less oil extracted, transported, and refined, inherently lowering the risk of oil spills and their subsequent environmental and economic damages.
Additionally, pipelines designed to carry oil across long distances have a history of spilling oil, causing significant harm to wildlife and the environment. Oil spills can contaminate water bodies, leading to water pollution and toxic algal blooms that kill aquatic life. The toxic compounds in oil can also have severe health impacts, including heart damage, stunted growth, and immune system effects.
By decreasing our dependence on fossil fuels and investing in renewable energy sources, we can reduce the risk of oil spills and protect our natural resources, wildlife, and communities. Renewable energy sources, such as solar and wind power, are now cheaper than fossil fuels, making the transition to cleaner energy more economically viable and environmentally necessary.
