No -- just think of Australia's rabbits and whatever it was that was
brought in to control them, and those monster snakes that are taking
over the Everglades. It's almost impossible to get rid of introduced
species (or invasive ones, too, such as the mussels that are clogging
up waterworks in the easternmore Great Lakes) -- yet Vancouver has
managed it, even if not by human doing.
