I think most of it has to do with fear and misconceptions about them, especially when it comes to the predators. I think that's most true about wolves, coyotes, and the big cats. Once one of those kill a pet or farm animal, everyone just assumes all of them will do the same thing, so they demand a law be passed to kill all of them and the governments at various levels agree. Unfortunately, doing that is easier than learning how to protect our animals without killing the predators. And you know how humans are ... they always take the easy way out.
True. Many ranchers in the western USA take to arms once they discover their sheep or cattle has been killed by someone, not necessarily a predator. They take a hasty decision and declare that such an such animal is responsible.
I would think this is just the natural process of life, some things have to die in order for others to live. Kinda like whats happening in Florida with the invasion of the snakes (constrictors), they have no natural predators and they are eating up everything and multiplying, throwing off the natural balance of the environment.
This is simply a serious case of misunderstanding. We see wolves and any other animals that can harm us as immediate threats. The case is even worsened by how the media uses these wildlife to depict evil. Through the years, wolves, lions, sharks, crocodiles, and other apex predators of the wild are used as main antagonists in the movies. I know they are simply aiming to tell a good story but we can't deny the effect of their actions in how the society thinks about these animals.
