You mean stratosphere Ozon layer, not the ground level, I think. The second one is harmful itself (the main component of smog).
Don’t forget the Ozone layer. Remember we were all gonna die from cancer? Never happened, of course.

Oh the more recent crap. I will say, we have had those warnings here a few yrs ago and and breathing is a motherfucker on those days. Def fear porn, but breathing sucks regardless
Yeah, the stratosphere. I remember the headlines in the tabloids when I was a kid. Terrified everyone.
