1.	Give scientific reason:A hole has been observed in the ozone layer in the stratosphere near Antarctica.
Answer» 1. Ozone layer depletion is mainly caused due to the action of CFC (Chlorofluorocarbon) molecules in the air. 2. Due to various increased activities of humans, the magnitude of air pollution has been increasing in the last few decades. 3. CFC molecules were used as coolants in refrigerators, freezers and air conditioners. 4. They were also present in industrial solvents, dry cleaning agents and hospital sterilants, aerosols and foam. Due to such enhanced use, much of the CFCs were liberated in the last few years. 5. CFC molecules are decomposed by ultraviolet rays which release chlorine and fluorine molecules. 6. Chlorine and fluorine react with the ozone resulting in a hole in the ozone layer present in the stratosphere. Therefore, a hole has been observed in the ozone layer in the stratosphere above Antarctica.
