I'm just hoping man will start to get educated and ecologically-aware enough to limit his fertility habits on his own. Mother Nature will have a cure for overpopulation: mass human suffering and death. If there are too few people in the world then manpower is limited and modern civilization and technology can't be supported also. Tribal humans are low in numbers but they can only support a primitive hunter/gatherer society. I believe that we could support and sustain a modern industrial society (air conditioners, automobiles, infrastructure, cell phones) with about 1/10 our current world population according to something I read online a number of years ago. Organic farming on a wider scale might even be doable for such a much smaller population. A mere 1,000 people in the world can't support air conditioning, cars, flushing toilets, electricity, advanced medicine and all that other nice modern stuff. Such a small herd of humans could live like cavemen of African bushmen. One man alone can only produce so much over his lifetime. Modern civilization is a tam effort to make possible. Could you scratch-build an entire modern automobile all by yourself from raw materials in the earth? Like producing a measly pound of deli meat, we could have a nice conversation about how many hands are involved in making a new motor vehicle and who gets what cut of the money involved. Building a new car, there is the iron mine and the rubber farm, and what else?
