The model I am used to is the http://www.footprintcalculator.org/ http://www.footprintcalculator.org/ despite the fact I don't really know what is behind the data.
It postulates, that if everybody would consume/travel, we would need two more earths to sustain that.
On the other hand, I heard that most of the big population bump were families still used to having 5+ children, because most wouldn't survive childhood, but medicine being just good enough to save them all. We no longer should have bumps of billion per decade as in the beginning of 20ct.
