  From: http://www.zo.utexas.edu/courses/THOC/land.html http://www.zo.utexas.edu/courses/THOC/land.html (Apologies for miles instead of kilometers.) > The total land surface area of Earth is about 57,308,738 square miles, of which about 33% is desert and about 24% is mountainous. In [1]: total_land_surface_area_square_miles = 57308738 ...: total_land_surface_acres = total_land_surface_area_square_miles / 0.0015625 ...: non_desert_non_mountain_acres = total_land_surface_acres * (1.0 - (0.33 + 0.24)) ...: acres_per_human = non_desert_non_mountain_acres / 7000000000.0 ...: print '%f' % acres_per_human ...: 2.253052 So about two-and-a-quarter acres of "good" land per human. And... > we have not allowed for any amenities such as highways, schools, hospitals, shopping malls, stadiums, agricultural fields, rivers, lakes, reservoirs, parks, golf courses, etc.

  Yes. The amount of land, excluding Antarctica, is less than five acres (about 2 hectares). The notional "40 acres and a mule" threshold was crossed in 1800. When you consider that land are translates directly to renewable energy flux, this becomes all the more interesting. Some growth trends from a few years back: https://ello.co/dredmorbius/post/_bi5uhywbdyukhfy-eayjw https://ello.co/dredmorbius/post/_bi5uhywbdyukhfy-eayjw

    our resources are limited. We have crossed carrying capacity 2 centuries ago. The world population has doubled in the past 50 years. I would hazard a guess that 4 billion is bearable. Optimal would be 2 billion.
