Gifford Miller was interviewed while doing fieldwork in Australia by INSTAAR affiliate Daniel Grossman for stories aired on National Public Radio and Radio Netherlands in March. Miller's studies indicate that Aborigines in Australia may have actually contributed to widespread climate change some 50,000 years ago (when the continent dried dramatically, fires raged and almost every species of animal larger than a bulldog disappeared). If proven, it would be the first solid evidence that technologically-primitive humans could alter the environment.
Others speaking on the shows include Rod Wells and John Kutzbach. "Aboriginal Climage Change" (NPR) and "Australia's Lost Giants" (RN) were both produced by Daniel Grossman and are available for listening on your computer with RealAudio.
