Yes violence increases in animals too if the environmental stress (biotic and abiotic) ratchets up. It stands to reason the same applies to humans although we have more conscious control over our responses but we don't often exercise them unless we're aware. These are all subtle mechanisms by which destabilising effects can cascade and proliferate. This is why ecologists and conservationists warned against unrestricted exploitation and an appeal to the assurance of science and technology rescuing us out of the resulting mess, but this is exactly the path we're down on.
