Can you provide a source for the mid-range estimate you mention? Global population is on the brink of decline rather than further growth. [1] > I've not seen any real understanding of why the fertility rate is dropping, particularly in first world countries. That's a concern; what happens if the factors causing this to happen are transient? The cited article discusses several potential causes and none are going away in the near future. On a global basis, humanity's current demographic profile locks in decades of either very low growth or a decline in most regions. Worth noting that these changes have all come about at a much faster pace than even the most aggressive estimates. Despite this as our overall numbers will start shrinking, resource consumption will grow and its growth can't be prevented by force without conflict. The only class of realistic solutions to environmental degradation are technological ones. Tapping into new stockpiles (likely out in space) and increasing efficiency slash decreasing resource intensity of economic activity are more viable if one aims to avoid armed confrontation.
