The elephant is total consumption. If somehow the total population was reduced by half tomorrow, but that half all consumed like the wealthiest today, we'd be in even worse shape.
That's just plain stupid; and that's the kind of thinking that has put the planet in such peril. I'm talking about one variable: population. You can throw in a bunch more variables and adjust them however you like to come up with whatever nonsense you like; but the fact is indisputable: more people require more resources, period. Positing some nonsensical argument about everyone living like Bill Gates is laughable. Of course people should be conscientious of the world around them, but that consideration is completely independent of the strain of overpopulation.
