What is one bad thing about using a fossil fuel for source of electricity?

One bad thing about using a fossil fuel for a source of electricity is the release of greenhouse gases into the atmosphere. The most common fossil fuels used for electricity generation are coal, natural gas, and oil. When these fuels are burned, they release carbon dioxide, methane, and other greenhouse gases into the atmosphere. Greenhouse gases trap heat, which leads to an increase in global temperatures and climate change. Climate change can cause a variety of negative effects, including more extreme weather events, rising sea levels, changes in agricultural yields, and loss of biodiversity.
