eli5, how did the ozone layer patch itself?
In: 75
Ozone is a naturally occurring compound and is in a cycle with oxygen called the ozone-oxygen cycle. This cycle is drive by the sun which turns oxygen into ozone and vice versa. Currently it’s not in equilibrium meaning there is more oxygen being turned into ozone than ozone turning into oxygen.
The entire reason the ozone was depleting was due to CFCs which REGULATIONS by governments eliminated. No more CFC meant the ozone could start rebuilding.
