OZONE DEPLETION
https://greentechfrontiers.in/ OZONE DEPLETION The decrease in ozone levels in the Earth's atmosphere is referred to as ozone depletion. A molecule called ozone is made up of three oxygen atoms. It shields life on Earth from the damaging effects of the sun's ultraviolet (UV) rays and is found in the stratosphere of the planet. Due to an increase in human activity that has resulted in the emission of chemicals that deplete the ozone layer, ozone depletion has recently become a serious environmental concern. Ozone Depletion Causes The atmospheric release of substances known as chlorofluorocarbons (CFCs) is the main factor contributing to ozone depletion. Before the Montreal Protocol restricted their manufacturing in 1987, CFCs were frequently employed in air conditioning, refrigeration, and aerosol sprays. When CFCs ascend into the stratosphere, the sun's UV rays degrade them, releasing chlor...
