Trapping Carbon Dioxide Underground: Can We Do It?

What Caused Ancient Upheaval to Australian Landscape?

Between about 45,000 and 50,000 years ago, Australia experienced three radical changes. The continent was once home to a menagerie of giant creatures, or megafauna, such as marsupial versions of lions, rhino-size wombats, giant kangaroos and flightless birds, but about 90 percent of that megafauna disappeared during this time. A major, relatively brief shift in plant life — from grasses to trees — occurred during this period as well. And last but not least, humans colonized Australia during this period.
