sorry, I should have phrased it better, I don't mean that hunting is declining because of moral reasons, I mean that as it declines and people grow more detached from it it will be considered more morally reprehensible. It is obviously an opinion not a fact, but as an example, you can consider the attitude of people to eating animals that they ate in the past and not now (porcupine, turtle, cat, dog). Not only it's considered disgusting, but it's often considered worse than eating other animals.
