Koalas
Koalas, an iconic symbol of Australia, face extinction as rapid urbanization 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.

"I truly believe that in my lifetime the koala will become extinct unless we do something," Deborah Tabarat, executive director of the foundation, told reporters.

Koalas are protected by law but the eucalyptus trees they call home and which provide their only source of food are not.

There are about 100,000 koalas in Australia, down from an estimated 7 million to 10 million at the time of white settlement in 1788. In the 1920s 3 million koalas were shot for their fur.
