Your comment didn't address any of my points. Your 'finite window of opportunity', besides being completely unjustified and probably wrong on a long-term time-scale, does not relate to overpopulation rather than, say, Peak Oil, and you ignored my point that the risk simply isn't there due to the demographic transition - which makes your claim that "Increasing population, especially in the developed world, consumes resources faster" simply wrong because places like Japan or South Korea (developed countries by any measure) are projecting decreases in population soon, and even the USA is growing mostly due to immigration.
