Answer:
Fossil fuels are formed from the buried remains of plants and animals over a period of millions of years. Coal, petroleum, and natural gas are some examples of fossil fuels. These fossil fuels are a major part of the world today and its varied uses have led to their over-extraction. The major consequences of over-extraction of fossil fuels are given below.
Exhaustion of existing reserves: The over-extraction of fossil fuels is slowly depleting the Earth of these resources. An energy crisis in the immediate future is a distinct possibility if the present rate of consumption of fossil fuels is not brought under control.
Air pollution: When coal and petroleum products are burnt as fuel, they give off carbon dioxide, a greenhouse gas that leads to global warming. They also give off pollutants like carbon monoxide* nitrogen oxides, sulphur oxides, particulate matter like mineral ash or fly ash, and unburnt hydrocarbons that pollute the air. Some of these gases combine with water vapour in the air and form droplets that fall to the Earth as weak forms of sulphuric and nitric acid, called acid rain.
Threat to organisms: Coal contains poisonous metals like arsenic and mercury, which are dangerous if released into the environment. Mercury that is released into the air settles in water with time. It then enters the bodies of fish and shellfish and can be harmful to animals and people who eat them.
