Dear student, Formation of ozone UV radiations of the sunlight act
on O2 to generate oxygen atom, which combines with O2 to form ozone
O2-----> O+O O+ O2 ------> O3 Effects of ozone depletion: 1
Ageing of skin, cataract, skin cancer 2 Killing of phytoplanktons,
decrease in fish productivity 3 Mutation in plant cells 4 Decrease
in moisture content in plants and excess loss of water through
stomata of leaves Depletion of ozone occurs because of the release
of chloro fluoro carbons in the atmosphere These chloro fluoro
carbons are used in refrigerators, air conditioners and hence there
use has to be restricted to save the ozone layer Thanks and regards
