There are many causes of global warming, I will talk about one cause which is ozone layer. The ozone layer is the earths’ shield which prevents amounts of ultra violet rays form reaching the fragile organic life beneath. Without this natural protective layer many living organisms on earth will not be able to tolerate the harmful ultra violet rays which will lead to their extinct. Therefore, unbalanced biological deficiency will significantly and rapidly affect other species. Hole in the ozone layer may form because of reaction with chloroflorocarbons allowing ultra violet light to reach the earth easily. As a result, serious environmental and health catastrophes will occur. The main factor that causes most of the ozone layer erosion is chloroflorocarbons, and they are industrial produced and mainly used as refrigerant in many applications these days. Manufactures are hard working side by side with specialized foundations and institutes to find other environment friendly compounds preventing the ozone from weakening.
