Air polution controls are admirably strict as it is (water and ground: they need LOTS of work, but air is quite good- and it's air pollution most directly accused of effecting climate changes). And I say ACCUSED- there is no conclusive proof that our activities have had any measureable effect on the heating or cooling of our world. The ozone, yes, we ****ed that one up.... but the temperature? Our planet's in a stage where it's slowly drifting closer to the sun. Has been since about the middle of the ice age. And will for a few million more years, probably to the point of turning our entire planet into desert and tropics. Then it'll start drifting out again. Until we see another ice age in another few million.
Humans won't be around to see that ice age. If our genetic descendants even exist anymore, they'll no longer be recognizable as human.
