CFC was hailed as a environmentally safe product, until we discovered it was destroying the Ozone..
I thought it was Mt Erebus blowing the hole in the ozone. The hole was directly above it.

The chemistry behind CFC and its effect on O3 is well known, and Wiki has an excellent summary of its effects..
en.wikipedia.org/wiki/Ozone_depleting_substanceBasically, the harmless CFC's float themselves into the upper atmosphere, where they get broken down by UV and release their Chlorine, which catalyzes Ozone..
Scientists caused a fuss over it, and people got upset over the science.. But they saved the F%$king world and everybody forgot how close we came..
Amazingly there is another chemical that was almost used instead of CFCs which was a million times
worse at destroying Ozone.. It was an accident of history CFC was chosen, it would all be over if we chose Bromodifluoromethane..
We have come close to destroying our only atmosphere, now it could be happening again and everybody is crying about a Tax.. idiots
