Hunting ? The only utility is when a kind of animal becomes too much strong and begins to pose a threat to others animals.
But I don't think it could be a sport or a hobby. Is it funny to kill animals ?
And recently, an old man has killed 2 persons in the street before to kill himself... with his rifle. So how can we know if the hunters have a healthy mind ? I accord it's a very rare event, but you also could have the temptation to resolve your problems just by a shot...
Moreover, I often ride bike in the forest, and during the hunting season, I have alright almost been shot... The guy didn't see me ! He thought I was a kind of stag or something like that... These men often think there are alone in the wood.
