INTRODUCTION

Fossil fuels are used for many things such as fuels for cars, bikes, planes etc…

They are also used to make medicines, cosmetics, plastics, synthetic fabrics, and lubricants.

A fact that you might not known is many tooth paste company use oil, to prevent the paste from sticking to our teeth.

Your shoes also a product that are made from oil.

FOSSIL FUELS

Fossil fuels are fuels that come from very old life forms that decomposed

over a long period of time. There are three most important fossil fuels. They are coal, petroleum, and natural gas.

These fuels are called fossil fuels because they are dug up from underground.

ORIGINPetroleum and natural gas are formed by

the anaerobic decomposition of remains of organisms that settled to the sea (or lake) bottom in large quantities under anoxic conditions (absence of O2), millions of years ago. Over geological time, this organic matter, mixed with mud, got buried under heavy layers of sediment.

LIMITS OF FOSSIL FUEL

Fossil fuels are the major energy source that are being used in the world today. But there over-consumption can lead to serious environmental issues such as air pollution. when burnt that can have severe consequences on their habitats. They are non-renewable sources of energy as they are derived from very old fossils and won’t be available once they are fully used.

SOME OF THE MAJOR LIMITS OF FOSSIL

FUEL ARE :

Environmental Hazards:

Environmental pollution is one of the major disadvantage of fossil fuels. It is a known fact that carbon dioxide, gas released when fossil fuels are burnt, due to this, global warming is caused. If such conditions continue, our earth might face many problems.

Acid Rain:

Sulphur dioxide is one of the pollutant that is released when fossil

fuels are burnt and is a main cause of acid rain.

Effect on Human Health:

Pollution from vehicles and coal powered power plants can cause serious environmental hazards. Air pollution can result in human disease like asthma, lung cancer etc.

Impact on Aquatic Life by Oil Spill:

Fossil fuels should be travelled to many place because of its

uncountable needs. Transportation of crude oil via sea can cause oil spill which can pose hazard to the aquatic life by lessening the oxygen content of water.

Coal Mining:

Extraction of coal from areas that have huge reserves is not only a difficult

and dangerous task but also poses a serious health hazard to the lives of several workers who work there. The coal mining destroys wide areas of land and results in environmental difference.

CONCLUSION

Fossil fuels are used for many things, but on the other hand it is more harmful for us an also the nature.

It should be used, but only in a less amount if it goes beyond the limit then we could face many problems.

So, use less amount of fuels and don’t depend on it more and use eco –friendly things and save our nature.
