FILE PHOTO OF A KOALA IN AUSTRALIA'S PORT MACQUARIE.
A koala sits in a tree outside the home of John Kouwenberg (R) in the
Australian town of Port Macquarie in this April 17, 2002 file photo.
Female koalas are being given contraception in the Australian state of
Victoria because the population is eating itself out of house and home.
Parks Victoria is planning to inject a small tube containing the same
hormones as the contraceptive pill under the skin of around 3,000 wild
female koalas in the Mount Eccles National Park, 300 km (186 miles)
southwest of Melbourne. REUTERS/Davd Gray/Files
