I think we've shown what a greedy species we are. I don't know what we can expect people to live a smaller life and consume less voluntarily. In my opinion, given our track record, that is why I suggested a lower total as a max. Maybe one day we'll be able to create energy and food locally that is carbon neutral and then we could handle more population but that doesn't seem possible now or anytime soon.
