Those are certainly the most basic. I think that peer pressure should also be increased to maintain proper ethics. I also feel that the recent decline in some people's ethics are the fact that so much land is being snapped up and posted drastically reducing the amount of available hunting grounds. When I first started hunting, you rang a doorbell, introduced yourself and politely asked for permission to hunt the land. You either got a yes or no. Now your threatened with trespassing before you even get to the door. I can somewhat understand this around someone's home but not out in the woods where there is nothing around for hundreds or thousands of acres.
