Habitability for humans . It's more or less a self-correcting problem
Our society is so odd. I find it astonishing that so many people can be cavalier about the deaths of millions of people when it comes to environmental destruction in a way that would be totally socially unacceptable if you were talking about targeted killings or genocide.
and really, even in cases that don't involve a superpower like china, I think if there was a random genocide in some random developing country, the world wouldn't do anything about it at this moment in time, the west is just too busy with its own internal problems at the moment.
