Important also is the rate of species extinction. An ecosystem with some number of species in it can likely cope with a low rate of extinction (as species get outcompeted quicker than the my evolve), but can't cope with several species dying out in rapid succession. The issue with humans is that we are rapidly increasing the rate of extinction, by pollution, poaching, exclusively occupying large tracts of land, clear-cutting forests, etc.
