Probably the burning of fossil fuels in industry, transport and to generate electricity. This releases additional carbon dioxide which is seriously damaging our planet by causing global warming. The US EPA has classified carbon dioxide as a pollutant.

As well as carbon dioxide, fossil fuel burning releases many other pollutants, such as carbon monoxide, nitrogen oxides, sulfur oxides, and hydrocarbons.
