Humans and "overpopulation" dispupting the evolution or the earth?

Overpopulation leads to more energy consumption and thus more waste including greenhouse gases which are depleting our ozone layer and going to make this planet uninhabitable. Sure other organisms would survive, but enviromentalists like select others with the ability to think with higher cognitive function are aware of this problem and the survival instinct kicks in. We don't want to kill ourselves off.
