You're assuming there is ecological balance In my country, idiotic victorians introduced several predator species (stoats, weasels etc.) back around the turn of the last century - a mere blink of the eye ago in ecological time. Since then, these species are steadily killing off our native birds species. Balance has not yet been reached, if by that we mean the extinction of those remaining species. Many very committed people work very hard on removing the introduced predators, and restoring the conditions that allowed the native species to thrive. I think we'll win, because technology.
