Human activity is driving Earth's 'sixth great extinction event' http://apocadocs.com/s.pl?1248866021
Earth is experiencing its "sixth great extinction event" with disease and human activity taking a devastating toll on vulnerable species, according to a major review by conservationists.
Much of the southern hemisphere is suffering particularly badly, and Australia, New Zealand and neighbouring Pacific islands may become the extinction hot spots of the world, the report warns.... Researchers trawled 24,000 published reports to compile information on the native flora and fauna of Australasia and the Pacific islands, which have six of the most biodiverse regions on the planet. Their report identifies six causes driving species to extinction, almost all linked in some way to human activity.
"Our region has the notorious distinction of having possibly the worst extinction record on Earth," said Richard Kingsford, an environmental scientist at the University of New South Wales in Sydney and lead author of the report. "We have an amazing natural environment, but so much of it is being destroyed before our eyes. Species are being threatened by habitat loss and degradation, invasive species, climate change, over-exploitation, pollution and wildlife disease."
