The world's first known identical twin koala babies are shown to the public by their keepers for the first time at the University of Queensland Koala Sanctuary in Brisbane in this February 20, 2000 file photo. Koalas, a iconic symbol of Australia, face extinction as rapid urbanisation along the eastern seaboard destroys their fragile habitat, environmental activists have warned. The Australian Koala foundation has written to the government urging it to declare the koala a vulnerable species after a survey of 1,000 koala habitats found 30 percent no longer had a koala in them and 60 percent had suffered widespread destruction.
