"On a global level, there is no threat to human survival greater than that posed by world overpopulation—paradoxical though that may seem—and it is abundantly clear that consensus decision making is ineffective for dealing with that. Some kind of “solution” is nonetheless unavoidable, and is certain to be ugly. To say that there is no visible world leadership on that transcendental question is to understate the case. Optimists on the population problem don’t measure progress in terms of a decrease in population, or even a decrease in the rate of increase, but in terms of a decrease in the rate of increase of the rate of increase."
