Malthus was right. Absolutely right. We postponed it, but it's still there and it's not going to go away because we wish it to.

Theoretically we could terraform Mars and Venus, but sheesh, that's really long term planning and how do you convince folks to move?

I suspect that either humans will solve their problem with a war that will kill half or mone of them, or ol' Mama Nature will do it with a plague or something else.

"Red in tooth and claw...." And don't ever forget it.
