Koala Food Chain Pictures

A koala and her young: these animals are facing extinction because of greenhouse gas poisoning eucalyptus leaves, their only source of food "Life will become of these animals is very difficult."Increased carbon dioxide reduces the eucalyptus leaf nitrogen and other nutrients to enhance the tannic acid, a naturally occurring toxin, by James Cook University researcher Ivan Lawler of the greenhouse experiment, we found.

This greatly reduces the level of leaf protein, requiring koalas and other animals to eat more nutrient-poor eucalyptus leaves to survive. "These animals are very delicate balance of the food chain, and a small change could have serious consequences," the newspaper quoted doctors as saying Lawler. Koalas and greater gliders, a large gliding possum, depend entirely food eucalyptus leaves.
