Watched the video and I thought it was shot with rosy glasses on, there is always a negative as well as a positive.... No hunting in the park? We'll bring in wolves.... Like John stated, not the type that would of been native too the area.... Let's bring in a mega wolf.....
So when they flourish and overextend their habitat then what? The video already said that the herds already avoid areas due too the wolves.... What happens when they get pushed off the park too private property and over graze there? Now you have ranchers who already are leery of wolves too begin with, having too worry more about the flow of food too the wolves onto their properties with them soon to follow....
