No Real problem Kompressor, its a personal view, I know lots of hunters, and like you, they take their hunt very seriously, they spend enormous amounts of time energy and money getting the right permits, the right equipment, knowing the animal, getting good trackers, ensuring the animal is never left to suffer and they only take what they can use themselves, no needless killing.
However, there is the flip side of the coin, those that hunt lions (and other animals) in cages (canned), here its all about money, greed and the trophy, they have no idea about tracking an animal,the vital areas to kill it instantly, their equipment is top of the range, but their skills in its use are non-existant, they could care two hoots about "sustainable population" they pay the money and want the trophy, if they injure the animal, they get back in the car and its killed by the owner anyway, it matters little, they still get the trophy.
I said early on hunting within permisable boundaries is fine, I dont like it, but its acceptable and dos no harm to the population in general, however, animals are big money, a lion costs $15000.00 to shoot in a cage, what chance dos the lion have?? - as we both agree, seal oil, genatilia, the carcass meat and the pelts are in huge demand commercially do you not think there will be those who will exploit the situation for money?
Here, seal culling is strictly controlled, but every year hundreds if not thousands of baby seals are clubbed to death illegally to fuel the black market fur trade, these animals live in remote areas, its nigh impossible to patrol everywhere, so the illegal killing gos on. Much the same can be said about the abalone along our coast, its nearly poached to extinction, recreational taking of abalone is limited to 8 per day (with a permit), just recently a poacher was caught with almost a ton, money has a way of making people forget their morals.
I agree seals are a threat to the fishing industry, but plastic bags, drift nets and plastic rings are a bigger threat to seals, in general most animal species today have to be regulated to a degree, that includes deep water fish, seals and the predators who live off them.
.....but in general I agree with your sentiments, actually they pretty much echo my own - except the hunting bit.!
