Environmental Consequences of Fossil Fuel Use

Fossil fuels are organic materials found inside the earth's surface. They are mainly composed of dead remains of plants and animals. The primary component constituents of fossil fuels are carbon and hydrogen, which are usually burnt to produce energy. Fossil fuels are believed to be formed millions of years ago when dead remains of animals and plants were subjected to high heat and pressure.
