you are arguing with someone who thinks 6.2 billion living humans is 5.2 billion too many. you are wasting your time.

So your solution is for us to breed ourselves out of existance and surrender the world to third worlders who have 6 children per woman? Sure less people would be great, as long as entire groups of people don't have to go extinct to achieve it, as is happening today.

Naahhh... I'm too squeamish for proactive genocide.
I'd prefer to genetically engineer a retrovirus of some sort which would attach to the X chromosome and in some way jack up the natural rate of miscarriage from 33% to somewhere upwards of 85%, then disperse it wery very widely, and then keep the vaccine under very tight wraps. I have heard very quiet rumours from contacts in the world of microbiology that something like this has been developed. That I have heard rumours of it strongly suggests that it has NOT been developed, but also suggests that others are thinking along similar lines.
OK, now that I have admitted to being the antichrist... There is hope: Never forget that lethal infectious microbes are making a comeback.
