18. From Cute and Cuddly to Feral Pests
Ever eager to economize, the British authorities shipped rabbits along with the convicts, the idea being that they would serve as a rapidly breeding food source. Eventually, some rich settlers had what seemed at the time to be a great idea: release rabbits and hares into the wild for sport hunting. Rabbits, which are not native to Australia, did not face as wide and lethal a variety of predators to keep their population in check Down Under as was the case in their native habitats. So from cute and cuddly and sometimes delicious animals, they morphed in Australia into feral and invasive pests that devastated much of their new home.
The consequences were catastrophic. As early as the 1820s, settlers were complaining of rabbits overrunning the place. By the 1860s, between the disappearance of many natural predators, mild seasons allowing for year-round breeding, and natural selection producing a hardier breed of wild rabbits, their population exploded.
