Well Gus does have point--be a good idea if your son distinguishs between sport, subsistance, and market hunting.
The really, really, bottom line: Sport hunting has provided the funding to restore most of the large mammals in the lower 48. And despite the less than stellar conservation ethic on the Campfire, sport hunting groups have often been very successful in the legislature, in the courts, and on the ground at preserving habitat and wildlife.
