Chlorofluorocarbons (CFCs) are a group of chemical compounds developed back in the 1930’s as safe, non-toxic, non-flammable substitute to treacherous substances like ammonia for purposes of refrigeration and spray can propellants. It was vastly used in refrigerators and air conditioners until we came to know about its drawbacks. The most threatening being depletion of the ozone layer due to accumulation of CFCs in the stratosphere. Stratospheric ozone protects living organisms on Earth from the harmful effects of the Sun’s ultraviolet radiation; even a moderately small decrease in the stratospheric ozone concentration can result in an increased incidence of skin cancer in humans and in genetic injury in many organisms. It may also affect our immune system and other diseases like eye cataract etc. CFCs also lead to global warming causing diseases such as malaria, dengue and many heart ailments. Hence it is necessary to cease the production of CFCs and aim for a healthier future.
