As a rancher in Texas, I have more problems with Cougars than wolves. Neither or an issue really. Wild pigs and coyotes are a problem and must be managed. Water and air quality (much improved since I was a child 40 years ago) and the depredations of apex predators (moronic politicians guided by ignorant electorate) are the real killers.

That said, there are places in N America where the reintroduction of wolves can be an issue if the numbers introduced are too zealous (too many for their natural food source).
