RE: Red foxes (Vulpes vulpes) were introduced to Australia for sport hunting in the 19th century, but ended up being responsible for the extinction of several native species, including the desert rat-kangaroo (Caloprymnus campestris)

Don't worry, foxes are not going to become extinct anytime soon! They are great at adapting to change, so they will stay around for a while ;)
