Wildlife Catastrophe Caused by Australian Bushfires Phil Mercer SYDNEY - More than 1 billion animals have been killed in bushfires in the Australian state of New South Wales, according to leading wildlife experts. Bushfires have had a terrible impact on Australia. Lives have been lost, thousands of homes destroyed and vast areas of land incinerated. The disaster has also had catastrophic consequences for animals. Images of badly burned koalas, Australia's famous furry marsupials, have come to define the severity of the fire emergency. The University of Sydney has estimated that more than 1 billion mammals, birds and reptiles, as well as "hundreds of billions" of insects have died in the fires. Experts have warned that "for some species we are looking at imminent extinction." They also fear that animals that have survived the fires by fleeing or seeking safety underground will return to areas that will not have the food, water or shelter to support them. .
