Perhaps the better idea would be to direct our children, our future, into the most beneficial directions that would improve their living conditions instead of limiting how many there are of them.
This.
If the Earth gets too small for us we could go to other planets and perhaps other solar systems. Interesting that the population density reaching critical mass and technological breakthroughs like Space Travel happen at the same time. Perhaps it was
no accident and maybe it was
intended to be that way? Maybe we're
supposed to be looking at other planets to inhabit at
precisely this time in our evolution? Hmmm.
But no, the OP thinks we should kill ourselves off. What a downer, thanks alot asshole.
