Ozone layer is a gaseous layer in the atmosphere. It exists about 30 to 60 km above the surface of the earth. It is like an umbrella that protects the living beings and plants from the dangerous and harmful Ultra

Violet Rays. The ozone layer is there at about 30 to 60 km above the earth's surface. It is a part of the earth's atmosphere. It acts like a protective umbrella and protects plants and animals from the harmful ultra violet rays of the sun. It acts like a filter and allows the essential rays to pass through it. A British Antarctic Survey team in 1985 detected 40% loss in the ozone layer over the Antarctica. After that scientists have

found that a synthetic chemical called CFC( cloro. Fluoro Carbon). has damaged the ozone layer. It is used in hair sprays, deodorants, shaving creams and many other cosmetic materials. It is also used in refrigerators.

These cosmetic products are used all over the world; chlorine present in CFC mainly damages the ozone layer. Many studies here pointed out that if the use of CFC remains at the present level, ozone layer will be damaged wherever chlorine gets concentrated. When the ozone layer is damaged ultra violate ray will come to earth's surface in full intensity and severely damage plants and animals. Therefore the ozone layer should be protected with all seriousness.

The following are some measures to Protect Ozone Layer Depletion:

(i) The use of plastic should be banned in the country.

(ii) The production and use of CFCs should be banned.

(iii) The use of CFCs in aerosol, spray cans, egg crates etc. should be banned and their substitutes should be used.

(iv) New technologies should be adopted to recapture the CFCs released from the air-conditioners and refrigerators.
