This is really SCARY.

I think humanity has turned this planet into hell

fascinating, thanks for the post.

Wow, I never thought that air pollution can be a positive in the larger scheme of things, and it is scary in some ways, but I don't think many nations or cities will be dramatically cutting their air pollution anytime soon (i could be wrong considering that many city mayors are trying to dramatically reduce all emissions by the year 2030 or later)
