I agree, however, hunting is important for keeping wild animal populations (mostly deer) in check, since humans have eliminated most of their natural predators like mountain lions. Therefore, it would need to be replaced with something else, such as state-operated culling (basically hunting, but done by professionals, and preferably in a way so that older/sick animals are killed rather than ones in their prime).
