There were flightless birds that weighed twice as much as modern emu, 33-foot snakes, 20-foot crocodiles, 8-foot turtles with horned heads and spiked tails, and giant monitor lizards that measured greater than 6 feet from tip to tail and were likely venomous. By about 30,000 years ago, however, most of these 'megafauna' had disappeared from the Sahul as part of a global mass extinction that saw the end of nearly all of the super-sized animals that had evolved to survive in extreme Ice Age climates. A new study has compared the diet of a variety of Australian megafaunal herbivores from the period when they were widespread (350,000 to 570,000 years ago) to a period when they were in decline (30,000 to 40,000 years ago) by studying their fossil teeth. The results of the study are described in a paper titled "Dietary responses of Sahul (Pleistocene Australia-New Guinea) megafauna to climate and environmental change" published on Jan. "Unfortunately, many of the advocates of the human predation hypothesis have discounted Cuddie Springs because it does not support the popular 'blitzkrieg' theory that maintains the megafauna went extinct in the 1,000-year period after humans arrived on the scene," said DeSantis.
Climate change is a topic that is something we should worry about. Climate change may have helped get rid of animals that could be a great harm to us, but we need to understand the facts and know that climate change is real. Climate change is something that we should worry about because it not only affects us, but it also affects the rest of the world. We need to be aware of what we are doing and how we can prevent climate change from changing our Earth.
