The grey wolf is a keystone species, which means it has profound value by keeping ecosystems in balance. Healthy ecosystems mean a healthy food chain. A healthy food chain means humans survival. We kill off wolves at our own peril. Frankly, if wolves were reintroduced east of the Rockies, we would see ecosystems across the country returning to healthy balance. We do not need cattle ranches to survive as a species but we do need healthy ecosystems as have existed on the planet until man’s hubris threw things off in recent eras.
