If you look in the population thread (https://bitcointalksearch.org/topic/decrease-population-2748857), many people want a way to control population. So, what is wrong with polluting? Pollution will reduce the population by destroying the habitable parts of the earth.
In other words, population will be poisoned to death by pollution. And they will be killed off by each other by each other, everybody fighting over the little bit of habitable land that is left.
So you see? All the modern conveniences of life are destroying the population by the pollution they create from their manufacture and use.
Besides, you are going to die anyway, from old age if nothing else. So why would you care if the pollution or population increases or decreases. You really need to get down to the basis of your thinking.
