What is the primary concern regarding fossil fuel usage?

The primary concern regarding fossil fuel usage is their contribution to climate change. When fossil fuels—such as coal, oil, and natural gas—are burned for energy, they release significant amounts of carbon dioxide and other greenhouse gases into the atmosphere. These gases trap heat, leading to the greenhouse effect, which causes global temperatures to rise. This warming is linked to various environmental issues, including extreme weather patterns, rising sea levels, and habitat loss, which substantially threaten ecological balance and human societies.

In contrast, while fossil fuels may be abundant in some areas, they are not free; they often come with significant extraction and environmental costs. Furthermore, fossil fuel usage does not promote biodiversity; rather, it often results in habitat destruction and pollution, which can harm wildlife. Therefore, it is clear that the primary environmental concern associated with fossil fuels centers around their role in accelerating climate change.
