Paul writes that it may be necessary to resort to involuntary sterilization to deal with overpopulation.
We may not be given time to make that choice. (Wizard posts information that there is evidence that the earth's climate is changing quickly and violently.)
Cataclysmic natural change is likely a primary tool for this planet to correct imbalance. Shedding excess population in that manner seems preferable to nuclear devastation.
Cataclysm would likely defuse the looming nuclear confrontation over diminishing resources. Lives and material possessions would be lost and we would be forced to find a new and sustainable ways of living.
Future generations would likely find a much better world than the one they currently stand to inherit.
