This was great writing but I believe it is missing a thought about the nature of things. So many ecological studies show that animals in nature, when over populated move away from the need to keep the species alive to things like homosexuality, murder (war,direct), and disease (not created by the animals directly unless the DNA does something) .
The nature of things is life's way of keeping a balance when the creatures themselves are not capable. We humans are just animals who are under the same basics of ecology.
