I'd add a couple of points: 1. Nature isn't an 'equilibrium' and doesn't have 'stable states'. It's a constantly changing complex system that can produce catastrophic changes without any external triggers. 2. What people view as 'nature' is often itself a situation that humans have created. For example in this post the preexisting situation was vultures feeding on livestock, but the vultures weren't doing that before humans were around.
