Art:""But Australia had mega Marsupials like mega Kangaroos and giant Wombats and gigantic birds but like 50,000 years ago the Aborigines moved in and they very quickly, like within a thousand years or so, killed off all the megafauna.And the Interior of Australia used to be much wetter, enough to where the trees made their own weather by cooling the temperatures down enough to where it rained and stayed wet enough for small trees and other brush grew. But the Aborigines hunted game by driving it with fire and it destroyed the ecosystem enough to change the weather. "---Maybe..maybe not.....50,000 years ago......things were a lot different here...the glaciers of the last ice age 25,000 years ago moved down over NY state..a mile deep. same over MI and NY.....and that's how the Great Lakes were formed....they didn't exist before then......SO you think the climate was the same with the northern third of North America under ice? Changing weather patterns? And that was only 18000 years ago.....Yeah..I bet the climate changed worldwide when the whole world was in the 'ice age' less than 20,000 years ago. The aboriginees probably did very litte....Out in NV, as you drive along the desert on Rt 50, there are a few spots where the hills go up a few thousand feet above the terrain..that causes rain the fall - and you have trees and deer ...for maybe a few square miles......the other 99% of NV is desert....along the route...Nothing to do with Indians...just the way it is ...t.
