The problem is we are messing with the environment and effecting NATURAL weather patterns and fluctuations in climate. The earth will not go to hell. It may if wee keep doing what we are doing for 500 or 1000 years. I think we should be focussing on having the smallest environmental impact possible.
A bigger issue should be looking at the amount of resources we use globally, because when we run out of resource. we're fucked. The US uses 50% of all the resources used globally each year, its time to change that.
