Which molecules destroy the ozone layer?
The number one molecule to destroy ozone, is water vapor. It both blocks formation of ozone (leaving NOx as a stable compound that some people mistakenly think destroys ozone), and it provides a decay path that does not require visible light to re-activate (via formation of H2O2, which also is unstable and will not form ozone when it decays). Beyond this, the others have named molecules that contain chlorine or bromine, and these also are compounds that decay ozone, that are more easily controlled at their source. And the lion’s share of these compounds that survive to reach the ozone layer, were made by Man.
