Bears are apex predators. Even a pavk of wolves are no match.
There are instances of Bears killing wolves and wolves killing Bears, according to Mech (1981), "wolves sometimes kill bears, but likely only young, old, or otherwise weakened bears."
There's more human biomass in this world than that of all wild mammals combined. The vast majority of that overwhelming human biomass is capable of using weaponry. In short, sorry bear but this victory is mine. Humanity wins by default.
