The Arctic people who kill animals for fur also use them for food -- it's not an "either/or" but and "and" situation. The hunters I know (and there are many) use all of the animal they can, and that can include the bones and "innards."

Those hunters also track wounded animals until they either find the animal and can "finish the job" or are completely certain that the animal will survive. This can mean following a blood trail for two or three days if necessary, knowing the indications of different "hits", and knowing the animal's habits. Gerber has come out with a special flashlight (usable in daylight!) that permits easier and more assured tracking of wounded animals.

I cannot understand those who would shoot any animal and then let it run off and die. That's not "human" and it's not, as the American Indians say, "honoring the spirit of the animal." If you are going to hunt, you owe it to the animal, to the concept of being human, and to the animal to do your best and if that means tracking a wounded animal for three days in the snow or hauling the body out of a canyon, so be it.
