If you are interested in this topic, you can research the plight of the wolf in Yellowstone National park. They were locally extinct, then 66 wolves were reintroduced in the early 1990s. Since then, they have reclaimed their spot as the top preadors in the park, spreading out into almost 14 different breeding packs with a population of more than 300 wolves. Not all of the repercusions were positive for the people living near Yellowstone, however. Cattle are now threatened by these wolves, among other things.
