I believe in Alaska that you are required to recover the meat of black bear, but not brown/grizzly. I eat everything I hunt, but not everything I trap. Have had beaver and muskrat, and they are good table fare. Generally save them for bait for trapping, or to feed temporarily caged fox for urine collection. Would do the same with bobcat meat. Fox, coon, skunk, and coyotecarcasses go in the chicken yard and the birds peck the bones clean, process, and return the favor in the form of eggs....or they get left in the wilderness where something else eats them.

General waste is not a good thing, but what really goes to waste in the wild? Killing ground, squirrels, prarie dogs, gophers, etc... generally goes along way to keep disease in the populations in check, as does trapping for many predators and furbears. A carcass will get consumed. If not from us, than by other mammals, birds, insects, etc.... That brown bear carcass did not last long after the hunters left it.
