I agree with hoodedclawjen. Also, I think when people who do actually hunt animals for food, they have a respect for the animals they hunt. I have family in the mountains of West Virginia. One IS an avid hunter, but he does not do it for sport. He uses the meat, and gives away the rest. Anything can be salvage for food or sale is. Nothing is thrown away. And i think he does not look upon the deer or whatever as just an animal to be killed.
I had a friend who went hunting in TX once, he was from another state. Unfortunately, he was there as a sport hunter, but the deer that he killed was donated to a community for the meat. So it wasn't wasted. It's meat ended up, for free, at a women's abuse shelter or somewhere.
Also you could look into info about some cultural/native peoples who believe in hunting as a religious-type ritual or it's spiritual and how it's how it's a sacrilage to not use, or to misuse, any part of the animal. Some peoples do not look upon this as a sacrifice but actually thank the spirit of the creature before or after killing. Some look upon animals as vessels of the gods. I am sure there's some useful good reasons for hunting in those stories somewhere.
