I'm firmly on your side of the issue. Humanity hasn't evolved the ability to make the sorts of changes needed on the scale they're required. Then the spread of conquest-based societies out the region around the Mediterranean 5 to 6 thousand years ago, at the tip of a bronze sword, gave us a double whammy. We evolved as a short-sighted species to begin with, and then developed societies that swept around the world, taking what we wanted from the world or other people, eradicating all the societies that were even remotely sustainable.
My hope for humanity in the wake of this pruning is that we will have a period of time when our behaviour will be ruled by more than greed and a need for status. That period will be short, because we are a short-sighted species, and will come rapidly back to the position that more is better. But it might be a nice break for a little while.
