Good points.
Hunting’s main purpose is not for food. It is for conservation, IMO. Without game harvesting, animal populations will explode and disease will run rampant. Deer, specifcally would die slowly from starvation because of overpopulation. More and more people would be dead or injured from deer-auto accidents, etc.
Not only that, but I usually keep the meat from 2 deer. It will last me all year. The rest is given to charity banks that feed the hungry. Hunting does a lot of good when you apply it the right way.
