Released animals can upset biomes that contain none of their predators, like rabbits and cane toads that are now spreading uncontrollably in Australia. If they eat similar foods to native animals they can put pressure on the very survival of those native species, like brown anoles from the Bahamas outcompeting native green anoles in Florida.
