Question

Explain ozone layer, its depletion and effects of ozone depletion.

Answer 1

Ozone layer is a protective gaseous covering which protects the Earth surface from harmful ultraviolet radiations. Ozone layer depletion is the process, which leads to gradual reduction in the thickness of ozone layer in the stratosphere. The most prominent reason for the ozone layer depletion is the use of chloro fluoro carbons.

The depletion of ozone layer can have following consequences:
1. It can lead to an increase in the incidents of skin cancer in human population.
2. Most of the phytoplanktons and zooplanktons will not be able to survive.
3. The crop yield will be severely affected.
