Oh, I don't know, I think we've done a good job of significantly reducing our resources in the past 500 years Sure, we haven't quite succeeded in bring our resources down to zero yet, but we've only just left the industrial age! Think of the possibilities once we really get some space-aged/nanotech-aged manipulations happening!
