Koalas are mostly solitary tree-dwelling creatures with peculiar habits.
Once hunted by the millions, koalas have been a protected species for decades. But as the forests of Australia are logged, and as cities spread into once wild land, the koala is squeezed out. At a nearby animal park, we meet a koala activist, Deborah Tabart, who says there are probably fewer than 100,000 koalas left. The U.S. government has listed the koala as a threatened species. Many Australians are aroused to try to save their national symbol.
