Correct Answer - Option 1 : Ozone depletion

The Correct Answer is ​Ozone depletion.

 

  • Ozone depletion means the gradual thinning of Earth's ozone layer in the upper atmosphere.
  • Ozone depletion is caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities.
  • Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons released into the atmosphere.
  • Ozone absorbs ultraviolet radiation which is harmful to humans, animals, and plants.

 

  • The Montreal Protocol (1987) is an international commitment to phase out ozone-depleting chemicals that was universally ratified by all countries that participate in the UN.
