I am all for decreasing CFC’s for the majority of common products (but not asthma inhalers which allowed drug companies to use their non CFC patent to jack the rates up from $14 an inhaler to $114 an inhaler so that now many kids don’t get their inhalers because they can’t afford them....all the while the amount of CFC’s from all inhalers combined is miniscule).
Undeniably, CFC's contribute to to ozone depletion , but they didn't solelycause it.
The hole over the Antarctic cycles as well, and CFC's contibutions are more noticeable during low ebb times of the cycle. It is not safe to say that anything has been "solved".
It will probably be back with the next cycle, though hopefully, less severe.
Anytime you see bureacrats pass legislation and then hear, "crisis averted", you should become suspicious. In those cases either the crisis is still there, or it was never there.
In this case, it is likely ongoing.
