Air Pollution To understand pollution of air‚ some knowledge of the atmosphere is required. Atmosphere is a layer consisting of a few gases surrounding the planet earth and is vital for the survival of life on earth. The atmosphere protects earth from abrupt temperature fluctuations from the powerful ultra violet radiation coming from the sun. The atmosphere is made up of nitrogen 78%‚oxygen 21%‚argon 0.9%‚carbon dioxideo0.03% and small amount of trace gases ‚helium ‚neon‚ krypton‚ xenon‚ hydrogen

[pic]! [pic] ‘I’ll go out for a breath of fresh air’ is an often-heard phrase. But how many of us realize that this has become irrelevant in today’s world‚ because the quality of air in our cities is anything but fresh. The moment you step out of the house and are on the road you can actually see the air getting polluted; a cloud of smoke from the exhaust of a bus‚ car‚ or a scooter; smoke billowing from a factory chimney‚ flyash generated by thermal power plants‚ and speeding cars causing dust

EARTH The earth is 4.5 billion years old. The Big Bang theory says that there was an explosion caused by the crash of matter which created our Solar System. Millions of years ago‚ during the Paleozoic era‚ the seven continents formed one single super-continent‚ from which they later detached driven by endogenous forces. Mankind appeared on Earth 30000 years ago. According to Darwin organisms which adapt the best to the environment they live in‚ survive the longest. Mankind become the dominant
