Can't we just rely on oil wars to reduce our population for us?
No, because despite how much people complain, the death toll is very insignificant compared to the world population.
yeah but we only have one going right now.
The USA has lost like what, 4000 people in 5 years. So if there were 100 going on right now, we would lose 400,000 people in 5 years. Not gonna solve much. There really isn't a feasible way to solve overpopulation, the best would either be:
1. Kill people, but that won't turn out well.
2. Make laws, same as above
3. Send some to Mars or something, long way off. As for pollution, hydrogen or something powered cars, advance solar technology (currently solar panels collect about 8% of total sun energy), things like that. Everything is at least 30-50 years off.
