why do fossil fuels cause pollution
Fossil fuels, even when burned perfectly (natural gas, or methane, burns the best) release carbon dioxide which is a greenhouse gas causing dangerous global warming. Most fossil fuels also release smoke (leading to smog), and they may also release sulfur oxides and nitrogen oxides which contribute to acid rain.  The burning of fossil fuels (coal, oil and natural gas) in  industry, transport and the generation of electricity releases  carbon dioxide (CO2) which is cau â¦ sing global warming.
