2023 study showed that as much as 10% of high atmosphere metal compounds were *already* pollution from space technology… and the challenge in that is that unlike other ozone deleters these molecules don’t get consumed, but instead the same molecule can catalyze an ozone destroying reaction again and again, while remaining in the atmosphere for decades.

As this pollution will take a few decades to descend to the ozone layer the problem is urgent, because by the time we start to observe significant ozone depletion any solutions or responses will take *more* decades to have any effect, and that’s even assuming that mitigation is possible. The only sensible solution is to stop putting this junk up over our heads in the first place.
