The koala，one of Australia's most treasured creatures，is in trouble.

Affected by habitat (栖居地) loss and climate change，like many other uniquely Australian animals，koalas are being squeezed into smaller regions.But at present，it is a deadly disease，a somewhat silent killer that causes a further decline in the koala population，that is worrying many scientists about the fate of the koala.

The killer is Chlamydia，which has caused symptoms in up to 50 percent of the wild koalas，with probably even more infected (感染) but not showing symptoms.It has been particularly severe in Queensland，where nearly all koalas are infected.The disease causes many symptoms including eye infections，which can lead to blindness，making it difficult for them to find their primary food.

Treating Chlamydia in wild koalas is a challenge.There is no treatment available for it．Only a small percentage of the animals can be treated successfully and returned to the wild.Besides，there is no national plan in Australia to save the koala；it is up to each region to make management plans for its koala population.

The good news is that researchers are working to test a vaccine (疫苗) that would help prevent further spread.If all goes well，plans can be carried out to distribute the vaccine more widely.But it's impossible to vaccinate all wild koalas.

Another possibility would be to make vaccine distribution a routine part of treatment for the thousands of koalas brought into care centers every year after they are injured by cars or dogs.

While it is a combination of problems that are affecting the wild koala population，many experts believe this vaccine would be an important step in helping koalas survive longer.It may buy enough time to give researchers a chance to solve some of the other problems facing Australia's koalas.

Australians have been warned they face a life or death decision over their water­drink recycled sewage or die.

With the drought continuing，the country is set to be forced to use purified waste water for drinking，even though there is great opposition to the measure.Queensland has become the first state to introduce the policy after a warning from its premier.“I think in the end，because of the drought，all of Australia is going to end up drinking recycled purified water，”said Peter Beattie.“These are difficult decisions，but you either drink water or you die.There's no choice.It's liquid gold；it's a matter of life and death.”Beattie said Australia's second largest state would become the first to use recycled water for drinking.

Water is recycled in Britain and parts of northern Europe along with the U．S.and Israel.But Australians have never liked the idea.To try to change the way Australians think，Prime Minister John Howard and Environment Minister Malcolm Turnbull have backed Queensland's move.“I am very strongly in favor of recycling and Mr.Beattie is right and I agree with him completely，”Howard said.Turnbull added that Australian cities，all now facing water shortages because of the worst drought on record，must start to use recycled water.“All of our big cities have to widen the range of water sources to include sources which are not dependent on rainfall，”he said.
