What does Alaska do when the protected prey outnumbers the predator?

Kill the prey.

Alaskan authorities have been killing wolves to keep moose and caribou populations preserved for human hunting, at rates of 60% to 75% sport.  When moose and caribou populations get so high they are unsustainable (because of course, the authorities over hunt the wolves), the authorities shoot the moose and caribou.  MMMM, hunting.
