Ozone layer is a layer in the earth's stratosphere at an altitude of about 10 km contains a high concentration of ozone in it. It absorbs most of the ultraviolet radiations coming from the sun rays.
If the ozone layer completely disappears, life would be impossible on earth. Without ozone, people, animal and plant life would be destroyed. The ozone molecules blocks the radiations which would otherwise burn our skin and cause cancer. Increasing exposure to the sun's radiation could also cause blindness and cataracts.
The main Ozone-Depleting Substances are:-
1. Chlorofluorocarbons(CFC's):- The most widely used, accounting for over 80% of total stratospheric ozone depletion. Found in industrial solvents, dry-cleaning agents.
2. Halons:- Halons cause greater damage to the ozone layer than do CFC's form automobile air conditioners.
3. Methyl Chloroform:- Used mainly in industry- for vapour degreasing, some aerosols, cold cleaning and chemical processing.
4. Carbon Tetrachloride:- Used in solvents and some fire extinguishers.
We can only save the world by avoiding the depletion of the ozone layer by the following ways:-
1. Limiting use of private vehicles
2. Avoid using pesticides
3. Banning the use of harmful nitrous oxides
4. Use eco-friendly household products and
5. Stop using CFC's.
Hope you will follow these instructions and save humanity.
