Ozone layer
Ozone is atmospheric gas that plays a key role in absorbing ultraviolet rays, which are harmful to life forms. The hole in the ozone layer is produced by a reduction in ozone levels leading to harmful gas emissions, such as CFCs (chlorofluorocarbons). Highly dangerous ultraviolet radiation can penetrate the hole in ozone concentrations.
