We need to act now to save the precious Australian Koalas. Scientists believe that by 2050 koalas will become extinct, we need to save these native species. Sign this petition to reduce the amount of eucalyptus trees that are being knocked down to make way for roads and cities, help the koalas today! Just imagine in 2050 when there are still lots and lots of koalas around and you could say to someone, I helped bring them back.
