I am rather tired of these human=monster BS. That has been crammed in *everywhere* again and again. It's like some humans hate their own Species for some reason.
See the "Matrix" movie. The good one. Agent smith has Morpheus captured and explains that every species on this Planet forms a natural Balance with its Environment except for two species, which would be a virus (which is not "a" "Species") and Humans. "Humans are like a Cancer to this Planet!" Smith explains, although a virus has very little to do with Cancer.
Well, "WRONG!". No Species on this Planet "naturally forms" any sort of Balance. They meat, they fuck and sometimes they get eaten. If they need more food then the habitat they live in has to offer, they will die out.
Many Animals have fewer offspring when food is scarce, but if a Plant or something that they eat is slowly dying out there will be nothing done about it to consume less of this Plant unless it is already scarce.
There is a natural Balance; Species which couldn't fit into it went extinct. If a Species becomes dominant enough to decimate their own Food source in their habitat (maybe even without humans interfering. Gasp!) they will do so. If their Habitat is so large that the extinction of their food plants will affect the planet, the animals will not have any trouble eating that Plant until it is no longer there.
We are the only species with some Specimen that try to do something about a Balance with their Environment.
Every other Species is like a Virus. If there's nothing there to keep their Population in check, they will procreate until there's no food left and they will have no choice but to move away and eat in another Area. Happened many times even without human intervention.
So some of us Humans are the exception to every single living thing who will consume resources with no care for what comes after them.
