I’m an Australian, The hole in the ozone layer was a real threat and my skin was definitely negatively affected by the amount of UV I was exposed to. When it was publicised, we saw a social and commercial shift in use of CFCs.

Aerosol cans with CFCs were removed and recycled (probably generating more waste, but whatever).

Mechanics and technicians working on A/Cs and fridges were much more careful with refrigerant.

10 years later, when the Hole recovered, we anecdotally observed less cases of severe sunburn. It may have also been a social awareness thing: with more people using Sunscreen et al, but the measurable reducing in UV was undoubtedly also a factor.

The benefit of removing airborne heavy metals (Pb-based paint and exhaust) is less measurable,but I feel that people with less exposure in their lifetime were more cognitive.

I also deal with a few people in my life who are CC denialists. They are also Y2K denialists so maybe they were exposed to significantly more lead paint than me…

I was gonna say, I bet this person also thinks that Y2K was overblown and that the polio vaccine was worthless.
