The correct answer is 1, 2, 3 and 4.

• Ozone and Ozone depletion:
  • The ozone layer is present in the Stratosphere.
  • The part of the stratosphere, in which there is a concentration of ozone, is called Ozonosphere.
  • This layer absorbs harmful UVA and UVB rays of the sun.
  • The temperature in the stratosphere increases due to the absorption of the ultraviolet radiation of the Sun by ozone present in this layer.
  • Montreal Protocol 1987:
    • It is an international treaty designed to protect the ozone layer from substances that deplete the ozone layer like Chlorofluorocarbons (CFCs).
  • September 16 is celebrated as World Ozone Day.
• Ozone Layer Depletion:
  • The ozone layer is the thin shield high up in the sky that stops ultra-violet rays from reaching the earth.
  • As a result of human activities, chemicals, such as chlorofluorocarbons (CFCs) were released into the atmosphere, which contributed to the depletion of the ozone layer.
  • Effects of ozone depletion  on human health:
    • Sunburn
    • Cataract
    • Skin cancer
    • Aging of the skin
