It only takes one to wipe us out
So then why worry about space rocks hitting Mars? The planet doesn't
seem to have been hit by any dino-killers as of late.
Even if you somehow magically make the Sol system space rock free,
humanity will continue to overpopulate Earth - 6.7 billion and counting -
so either you colonize or let the governments come up with some nasty
ways of bringing the numbers down - or let nature do what it always
does when a species gets overabundant.
I think colonization is a bit nicer, don't you? Well, you probably don't,
judging by your previous posts, but I thought I'd ask anyway.
And yes, there are and will be better things than humanity one day.
They'll colonize the galaxy right.
