Gus,
many in biology believe humans are just another life form. Many, if not most life forms, in an unrestricted or lightly restricted growth phase don't just slow down when they reach maximum carrying capacity..............
they crash.
and then go through cycles of boom and bust.

Will it happen to us? Who knows, we are different in a way, as we have "technology" on our side, right?

PS, the ALIENS are coming to absorb our nutrients anyway, so let's just keep on keepin' on.
