That's because the ban on chlorofluorocarbons in aerosols and fridges and other devices has had a huge effect on the environment. These "Frankenstein" compounds that are never found from a natural sources.
Chloroflurocarbon gas molecules are broken down by ultraviolet radiation after a period of time, many tens of years. Bit of a bugger when the CFC ban came in though.
Amongst other things back in the late 80's and 90's it was widely used in industry as a solvent including to degrease and wash really precision optical components and when the ban kicked in it really screwed up a program I was running!
The replacement was ---- problematic to say the least. And bloody inflammable too whereas CFC were not and that's why today most aerosol cans make good flamethrowers just because of the propellants now used in place of CFC's.
