Eli5: how can earth ozone layers heal itself even with our high pollution level?

In: 5

Answer 1

Ozone layer is not damaged by all pollution, only by specific chemicals that reacts with ozone in a particular, a chain reaction-like way. Majority of those chemicals aren’t pollutants from industry, but industrial chemicals that have leaked into the atmosphere due to lack of regulations and accidental discharges. Car A/C refrigerants for example.
So as long as we stop leakage of those particular chemicals (bybiposing strict controls over handling, or replacing them with different ones), ozone layer helps over time.
