Almost every human population is under strong selection pressure towards having more people. This dip in fertility cannot and will not last.

Easter island -- we, humans, deforested the island, that degraded and depleted human population significantly even before the first european ships discovered the island. From what I've heard, "Rapa Nui" movie is unusually historically correct on the events. 2. St. Matthew Island -- 29 introduced reindeer rapidly overpopulated the island and ate all the available food there, so the whole population died. Same thing can happen on planet Earth.

More recent research shows that this is probably not true - there's evidence that the population was growing right up until the arrival of Europeans[1].

It is almost like humans are not mindless animals who solely reproduce because of biological urges or something.
