it's funny how all the movies from the '70s and '80s (and even some from the '90s!) just assumed that smog would get worse and worse until the earth (or at least LA) was perpetually shrouded in smoke, then the government banned smog and it went away; incredible really.
Acid rain went from being a pollution disaster to an environmental success story. How did scientists manage to prove that acid rain existed,
similarly "acid rain" was a genuinely devastating problem that was solved, eventually, by banning it! turns out you can just do things.
