Differences between killing pests that damage a farmers yelds, compared to vacationing to purposely relax and enjoy killing animals.
Duh'
Depends how its done. Bambi destroys forests if left unchecked. Wolves aren't enough unless there is lots of them. Besides we are animals too we also need to eat. What your main concern is hunting in such a way that doesn't lead to extinction or major imbalance. Occasional hunter that goes out and shoots a deer isn't going to upset the ecosystem and is infact needed. Otherwise government uses taxpayer money to send out hunters on helicopters to cull the deer.
