What is a major disadvantage of using fossil fuels?

The use of fossil fuels is associated with significant environmental impacts, notably air pollution, which is one of the major disadvantages of relying on these energy sources. When fossil fuels such as coal, oil, and natural gas are burned for energy, they release a variety of harmful pollutants into the atmosphere. These pollutants include carbon dioxide (a greenhouse gas that contributes to climate change), sulfur dioxide (which can lead to acid rain), nitrogen oxides (which contribute to smog and respiratory issues), and particulate matter (which can harm human health).

Fossil fuels, while historically abundant and relatively inexpensive, have defined disadvantages that affect air quality and public health. The emissions from burning these fuels are a major contributor to environmental problems, making it crucial to consider alternative energy sources that are cleaner and more sustainable.
