OZONE DEPLETION and its effect in our environment

Facts about ozone depletion

3. The ozone layer is mainly found in the lower portion of the eart
atmosphere. k has the potential to absorb around 97- 99% of the
harmful ultraviolet radiations co un that can damage
life on earth. Ifthe ozone layer was absent, millions ple would

Researches say that the unregulated launching of rockets results in
much more depletion of the ozone layerthan the CFCs do. I not controlled,
this might result in a huge loss of the ozone layer by the year 2050.
