Is that a bad thing? All other animals have population collapses from time to time and it redresses the balance. I don't see it as particularly catastrophic.
Of course, now this reduces to how we define catastrophe, and we obviously have a difference. But I see a halving of the human population hardly a catastrophe at all, whereas the permanent extinction of species a much worse thing.
