"It was calculated already in the 1960s by the Agricultural Economics Research Institute, Oxford, that the agricultural productivity, even at that time, would be more than sufficient to feed 45 billion people globally."[1] Granted, there's much more to sustaining humans than just food, but come on let's apply some engineering to the problem first before giving up. There's another, better reference but it escapes me at the moment- something calculating that with various engineering techniques applied to the planet, 100 billion people shouldn't be an issue. Edit: Wow has it been 15-17 years already? Good seeing you. [1] Agricultural productivity in relation to population, 1963
