I've never seen any meaningful evidence of ozone loss. Yes, yes, yes, I know, there was publicity and/or propaganda of a big ozone hole over the Antarctic, right, in the winter in the Antarctic when there was no sunlight at all. Semi-, pseudo-, quasi-amazing. It was presented just as propaganda, not as solid evidence with who measured it, how, when, where, etc. with comparisons with elsewhere, with the Antarctic at other times of the year and in other years, the Arctic, etc. It was just propaganda. It wasn't much better than the Mayan charlatans claiming that without pouring blood on a rock the sun would stop moving across the sky.
"Keep trying"? Sounds like medicine 500 years ago -- let's try some of this sulfur, now some of this broth of boiled rat tails, now some of these leaches. We've had hundreds of years to know that such mindless, irrational throwing trash against the wall to see what sticks is just wasteful or dangerous and we shouldn't do it.
Or, if it ain't broke, then don't fix it, and so far there is no good evidence that anything is broken. Moreover, even if there is a problem, there's still less evidence that humans are the cause.
Much stronger evidence is that some manipulators and propagandists can make people feel guilty for no good reason. It's social and psychological, not physical or scientific. Some good technical people can be a bit eager to believe that there is a genuine problem and a bit slow to see just simple, silly, psychological manipulation.
"Consequences of ozone loss"? Yes, the "consequences" would be bad, but we shouldn't worry about such consequences until we have some solid evidence of significant "ozone loss" due to human activity, and so far we don't. There would also be terrible "consequences" if the sun quit shining, but we don't try to DO something about that yet.
You are acting like someone convinced you that you are a terrible sinner, that you are doing something very wrong, and that you need to sacrifice this and that, whatever, until you are no longer doing something wrong, etc. As I outlined, that's a very old, dirty, destructive, manipulative mind trick. You've been totally taken in.
Instead, it's much more likely that you should be concerned about being manipulated by a hidden agenda, that you should follow the money, that you should know that politics is more important than ozone. It's just not about ozone.
Warm, sincere advice: Just gotta be really gullible to believe that this is actually about ozone. Or, some people want to be on your back and into your pocket. Not nearly a new story, but one, a scam, that has worked for 1000+ years.
Why? Because people tend to be afraid. And, when in doubt, still be afraid. Be afraid of anything that goes "bunp" in the night. Be afraid of what's under the bed. Be afraid of anything new. Be afraid that are doing something wrong. Be afraid when authority figures talk about the sky is falling. Then, afraid, believe that need to do something, certainly not just do nothing. So, something, say, what some manipulative propagandist authority figure is saying to do. Let them be on your back and pick your pocket. Let them ruin your A/C and, then, sell you new A/C at much higher prices, all for no good reason of science or engineering.
It's a scam. It's time to call it a scam.
