CANBERRA, Australia — "Koalas are threatened by the rising level of carbon dioxide pollution in the atmosphere because it saps nutrients from the eucalyptus leaves they feed on, a researcher said Wednesday.
Ian Hume, emeritus professor of biology at Sydney University, said he and his researchers also found that the amount of toxicity in the leaves of eucalyptus saplings rose when the level of carbon dioxide within a greenhouse was increased.
Hume presented his research on the effects of carbon dioxide on eucalyptus leaves to the Australian Academy of Science in Canberra on Wednesday.
The researchers found that carbon dioxide in eucalyptus leaves affects the balance of nutrients and "anti-nutrients" — substances that are either toxic or interfere with the digestion of nutrients.
An increase in carbon dioxide favors the trees' production of carbon-based anti-nutrients over nutrients, so leaves can become toxic to koalas, Hume said."
About time. Since none of the big cats made it from Indonesia to Australia, ridiculous animals have flourished due to lack of predation from more advanced species.
Now at least we don't have to nuke 'em.
