Wild game is a renewable resource. Polar bears reproduce while young, and when they get old they die, just like any other animal on the planet. Trophy hunters are interested in big, old, bears, and killing such a bear, or any other animal, in the last year or two of its life has no effect on the overall population of that species. Trophy hunters are after a specific animal, a very smart and successful animal, living in one of the most hostile environments on the planet. By comparison, meat hunters are non-specific, and will shoot any legal animal they encounter. While there isn't anything wrong with meat hunting, provided its practiced within the parameters of good management procedures, I bring it up to illustrate the low impact trophy hunting has on the health of a species. Its much more challenging to hunt an old experienced, successful, specific animal than it is to hunt just any herd animal. The animals that kill the most number of polar bears are other polar bears; adult male bears commonly cannibalize cubs, and so will a sow under some conditions, and I have photos to prove it. The slogan should be, "Save a cub, shoot a boar". This animal rights group is less interested in the health of polar bear populations, and more interested in advancing their particular agenda.
