I am impressed that brown bears and wolves can be found in Western Europe, given the population densities. If you want to have bears and wolves in close proximity with people, problem predators need to be dealt with. This particular incident with the bear and sheep seems more bad luck (for the sheep) than anything else. But large predators need to fear humans.
