The main (or most publicized) culprit of this ozone loss was a chemical called [...]

A class of elements called halogens (fluorine, chlorine, bromine, iodine, etc., often occurring in pairs) are emitted into the atmosphere via ocean spray, where they destroy ozone (O3), a significant greenhouse gas and aerosol that promotes warming.
