The pollution resulting from fossil fuels is caused by the toxic emissions they release. Fossil fuel combustion releases carbon dioxide, nitrogen oxide, methane and other emissions in the air.
One of the more serious consequences of pollution caused by fossil fuels is global warming or climate change. Fossil fuel combustion introduces the so-called greenhouse gases into the air. Scientists believe that carbon and other emissions in the atmosphere created ground level ozone. This layer traps heat at the Earth's surface, causing land and water temperatures to rise. These temperature increases in turn cause sea levels to rise due to melting ice caps.
Fossil fuel combustion directly impacts the air, causing widespread pollution. However, chemical reactions in the atmosphere can also lead to harmful effects on land and in water resources. Acid rain, for example, is the product of a chemical reaction involving sulfur dioxide and atmospheric moisture. The resulting acidic precipitation contaminates aquatic environments and pollutes soils.
