Koalas being poisoned by global warming

Koalas are one of my favourite creatures on the planet, in fact years ago living in Australia I had Koalas living in some Eucalypt trees at the bottom of my garden. They would visit for a few weeks then disappear to some other part of town where fresher leaves were growing.

So you can imagine how sad I was to read that their only source of food, the eucalypt leaf is starting to become poisonous to them because of global warming and the increased percentage of carbon dioxide in the leaves.

These gentle little creatures have evolved into a really special little animal that never fails to generate excitement in everyone when you spot them in the trees.

To think that they could quickly become endangered because of lack of food is terrible, and I guess if this is true and continues then at some point they may be restricted to zoos and sanctuaries where eucalypts can be grown in controlled conditions with artificial air. Its very sad, I hope scientists can come up with some way to protect the Koalas.
