Lack of Predators

Predators help keep herbivore populations healthy by taking out the sick and the weak. This promotes stronger, healthier genetics in the next breeding season, and prevents overpopulation which can lead to disease spread or even over browsing followed by starvation events.

Some claim that this is why hunters "must" hunt dear, however they tend to hunt the largest and healthiest animals, which leads to weaker, less healthy animals breeding in the future. Elephants have evolved to have smaller tusks, and deer tend to have less impressive antlers after multiple generations of this behavior. Fish populations suffer similar problems because humans choose larger fish, and throw back the smaller, less fertile specimens.
