Mass Extinction Underway?

According to a new paper released by the science journal Nature, mankind may have unleashed the sixth known mass extinction in Earth’s history.

Over the past 540 million years, five mega-wipeouts of species have occurred through naturally-induced events.

But the new threat is man-made, inflicted by habitation loss, over-hunting, over-fishing, the spread of germs and viruses and introduced species, and by climate change caused by fossil-fuel greenhouse gases, says the study.

Evidence from fossils suggests that in the “Big Five” extinctions, at least 75 percent of all animal species were destroyed.

I guess the good news is that the Earth survived the first five extinctions?
