The Great Drought: Last Glacial Maximum 30,000 - 15,000 BP For thousands of years people live with Australia's strange and ferocious megafauna like the 6 metre giant lizard Megalania and the marsupial lion. These beasts all become extinct as massive climate change hits Australia brought on by the Last Ice Age. Sea levels drop 130m and deserts spread from 60% to 90% of the continent in the biggest drought ever experienced by humans. As conditions worsen, rather than moving, people adapt to the new environments. In many parts they become desert people with new technologies like the grindstone. Over 10,000 years of punishing drought people developed a culture and a Law that enabled them to survive in places we can't live in today.
