ars CFCs were used in air conditioners, refrigerators, spray cans and were a big part of quite a few manufacturing processes. CFC molecules are just about indestructible until they reach the stratosphere. At this point, intense ultraviolet radiation (UV-rays) breaks the CFC molecules apart, releasing the chlorine atoms they contain. These chlorine atoms begin reacting with ozone, breaking it down into ordinary oxygen molecules that do not absorb UV rays. Mention on the website The Environment a Global Change (a single chlorine atom can destroy up to 100,000 ozone molecules in the ozone. A chlorine atom combines with oxygen and starts to deplete the atmosphere .) (n.p.) Further ozone loss is expected in the future because CFC molecules already released into the lower atmosphere will be making their way to the stratosphere, which process takes decades.
