I do not hunt deer, but do not see a problem with it, as it is a huge problem that we, the humans, have created. We hunted to near extinction all the white-tailed deer's natural predators - wolves are extremely rare back east (here), for example. I have seen deer, dying of starvation or dea by the side of the highway in upstate New York years ago. It is far less cruel to shoot a healthy animal and use its meat to feed people than to see the forest ecology destroyed, and the deer population slowly starving to death.
