Earth 'entering new extinction phase' - US study

The Earth has entered a new period of extinction, a study by three US universities has concluded, and humans could be among the first casualties. The report, led by the universities of Stanford, Princeton and Berkeley, said vertebrates were disappearing at a rate 114 times faster than normal. The findings echo those in a report published by Duke University last year. One of the new study's authors said: "We are now entering the sixth great mass extinction event." The last such event was 65 million years ago, when dinosaurs were wiped out, in all likelihood by a large meteor hitting Earth. "If it is allowed to continue, life would take many millions of years to recover and our species itself would likely disappear early on," said the lead author, Gerardo Ceballos.-READ MORE-http://www.bbc.co.uk/news/science-environment-33209548
