"Based on an actual event, Wolf Island explores what happens when nature's delicate balance is undermined. A family of wolves leaves its island environment. At first their absence goes unnoticed. But now tht the highest link in the food chain is gone, the deer begin to multiply. Eventually there are so many deer on the island that thee isn't enough vegetation to feed them all. Every other species is affected in its turn. The mice, rabbits, squirrels, and owls soon face starvation. It isn't until the accidental return of the wolves that the island habitat slowly begins to recover."
