Scientists have discovered three new chlorofluorocarbons (CFCs) that have contributed to the deterioration of the ozone. CFCs is a gas that is used in refrigerants and propellants in aerosol cans. When scientists discovered the hole in the ozone over Antarctica in 1985 they found that CFCs were the cause. And “[because] the annual ozone hole breaks up in spring, pockets of ozone-depleted air sometimes move...

       In May 1985, scientists discovered the ozone value had decreased over the Halley and Faraday Research Station when the Sun appears every recurring spring. The stratosphere was depleting rapidly. The culprit was chlorofluorocarbons (CFCs). CFCs were commonly used in refrigerants and aerosols but were replaced by hydrochlorofluorocarbons (HCFCs). Although HCFCs are somewhat safer, they were replaced again by Hydrofluorocarbons (HFCs). Through ozone depletion,...
