Ozone is an allotropic form of oxygen in which there are three atoms in each molecule. It is a gas and occurs naturally in the stratosphere of "Ozone layer". This Ozone layer protects us from high energy ultraviolet radiation of the sun, which will otherwise kill living things. Ozone is used as a sterilizing agent in hospitals because it is disinfectant. The life could not start on the land surface of the earth until the Ozone layer developed. Man made chemicals are eating away at the atmospheres Ozone layer - a crucial shield without which ultraviolet rays would cause wide spread skin cancer and damage to much needed crops.
The existence of a vast Ozone hole was noted over Antarctica in 1985, of the size of the United States and the depth of Mount Everest. This Antarctic hole develops every year in September and October. During that period, the Ozone contents of the stratosphere over the pole diminishes by 40%. The main culprit for the depletion of Ozone layer is said to be Chloro Fluoro Carbons (CFC). The CFCs are gases, cheap and non-polluting at the ground level, and these are used to perfume dozens of important functions in manufacturing and in every day life. They are used in refrigerators and air conditioners.
