... CFCs reach the stratosphere, the sun's ultraviolet radiation cause them to break apart. Therefore, the chlorine atoms inside the CFCs are released and will react with ozone, starting a chemical destruction cycle of ozone. To show the extent of destruction chlorine can produce, one chlorine atom can break apart more than 100,000 molecules of ozone. Chlorofluorocarbons are not naturally produced chemical ... by 15%.

... the production of CFCs in 1996 in the developed countries. The measures that had taken part have helped the ozone layer. Researchers believe the atomic chlorine levels will reach their peak soon and in the next 50 years the ozone layer should be able to rebuild itself. Health Ozone depletion also causes major health problems because of the effects that the ... years but most are destroyed sooner than that. With there long lifetime, they can do a lot of damage destroying ozone molecules for a long time. CFC's have altered the natural ozone cycle in the stratosphere. They destroy the ozon...
