There is always an anthropocentric view with being human. Yet if we take Darwin’s conclusion seriously then we are just another animal on this planet.
This being so we are not “unnatural” but truly just part of the entire animal kingdom and should be treated as such.
The way we consume resources is as natural as that of other animals. We are genetically programmed to take as much as we do. If natural selection is to work on us as it does on other animals then some kind of balance will come about.
Apparently some lobsters and eels form a symbiosis for survival. From the point of view of natural selection it would make sense that lobsters or eels who do not form this symbiosis may have a power chance of survival thus such animals being “weeded out” naturally. Perhaps just in the same way humans are weeded out by the system.
