They don't seem to answer the question of why the chlorine in the atmosphere comes mainly from CFCs. What about all the chlorine we use every day from e.g. bleach and swimming pools? Does that not wreck the ozone layer because it never gets high enough into the atmosphere?
- Uehreka 4y agoI guess that would be nice background, but you can also find the answer in like 5 minutes on Wikipedia. https://en.wikipedia.org/wiki/Chlorofluorocarbon https://en.wikipedia.org/wiki/Chlorofluorocarbon From the section on Regulation: > It turns out that one of CFCs' most attractive features—their low reactivity—is key to their most destructive effects. CFCs' lack of reactivity gives them a lifespan that can exceed 100 years, giving them time to diffuse into the upper stratosphere. Once in the stratosphere, the sun's ultraviolet radiation is strong enough to cause the homolytic cleavage of the C-Cl bond.
