The gray wolf as a species is not in danger of becoming extinct. In addition, there are close to 100 wolves already in Montana, Idaho and Wyoming. The introduction program was not done to save the gray wolf. Since the gray wolf population does not need protection, this program also was not done for any of the reasons that are listed in the Endangered Species Act. Rather, it was done to artificially increase the number of wolves already existing in these three states.
Wolves kill livestock and pets.
There is absolutely no dispute about that from anyone. Ranchers and farmers are concerned that wolves released by their government will kill their livestock and maybe force them out of their livelihood without taking any responsibility for these consequences. Introduced Canadian wolves have killed livestock and have caused problems for some people. This is not a question about preserving introduced wolves in Yellowstone National Park. It is much larger than just wolves in Yellowstone Park.
