Fossil fuels also give out sulphur dioxide into the air, which after reacting with the moisture in air, produces sulphuric acid and leads to acid rain. Acid rain causes severe damage to the living as well as nonliving matter on the earth. Oil is often transported from one place to another by the means of sea route. During this oil spills occur on the ocean surface and that causes severe harm to the marine life. Fossil fuels have a high On burning of fossil fuels, calorific value. In other words, large amount of carbon combustion of fossil fuels dioxide is released into the generates a large amount of atmosphere. This can cause usable energy and are global warming considered as high efficiency fuels. Prices for fossil fuels are Fossil fuels are stable in going up as they run out. nature The search for newer location Fossil fuels are non for oil reserves is a highly renewable source of energy expensive process with a very and are being used up very low success rate.

Due to mining of the Fossil fuels generate millions coalfields, landscapes spread of jobs world wide over large areas are being destroyed and cannot be used for any other purpose. Coal is easy to transport from Some of the by products one place to another, and oil obtained during processing and gas can be moved by of the fossil fuels are highly pipelines toxic too.
