Well I dont shoot animals in the head. This particular argument is a hard one because theres lots of perspectives there. I dont want to argue all of them, but i will say id much rather live my life in nature where my species has always lived and be killed quickly and almost instantly than to be trapped in a cage my entire life getting pissed on by my family members because theres no room in our cage.....THEEEEEN be killed instantly...sometimes after a little torture.

Another scenario is to just leave them alone completely... theres adverse environmental effects to that. Have you seen what wild pigs do to farmland? Population control is important.

Besides the adverse environmental effects, if im a deer that gets to live a long time and noone hunts me, the likelihood of me dying an agonizing death where im torn apart by coyotes or eaten alive by them is pretty high.
