What is one of the main cons of fossil fuels?

Fossil fuels, such as coal, oil, and natural gas, are major contributors to greenhouse gas emissions, particularly carbon dioxide (CO2) and methane (CH4), when burned for energy. This process is a significant driver of climate change and global warming, as these gases trap heat in the atmosphere, leading to various environmental impacts, including rising sea levels, extreme weather events, and disruptions to ecosystems. The extraction and combustion of fossil fuels release large amounts of these pollutants, making their use a critical environmental concern.

In contrast, the other options highlight either positive attributes or misconceptions about fossil fuels. For instance, they are neither non-toxic nor infinite in supply, as fossil fuels are finite resources and their extraction and use can produce harmful pollutants. Additionally, while fossil fuel industries may create jobs, they do not relate to renewable energy, which is generally associated with cleaner alternatives that reduce greenhouse gas emissions.
