CFCs (chlorofluorocarbons) were banned because:
- Oxygen depleting substances (ODS) like chlorofluorocarbons, nitrogen oxides, chlorine, carbon tetrachloride, etc. convert ozone to oxygen.
- As a result, the high radiation ultraviolet (UV) rays will be in a position to pass through the ozone layer and will have direct access to our planet.
- The ultraviolet rays will lead to health hazards.
