THE purpose of great discovery of Mario Molina and F. Sherwood Rowland is to just highlight the harmful effects of CFC, the combinations of chlorine (C), fluorine (F) and carbon (C) atoms, which are being used in multiple things such as refrigerators and aerosol.
The ozone layer protects the earth from dangerous ultraviolet radiation (UV), which can cause mutations. In humans a depleted ozone layer would likely mean higher rates of skin cancer, cataracts and immune system problems.
Further, an increase in UV radiation could affect plants and marine ecosystems which could, in turn, trigger other ecological changes. The UN should take serious action against the production of CFCs and it should be internationally banned.
