Sixth Mass Extinction May Have Already Started: Study – huffingtonpost.com

Posted by erauch, March 13, 2011

Scientists say the next mass extinction may already be under way.

A new study, published in the most recent issue of the journal Nature states just that. And it’s man-made.

The theory comes from research done on the state of mammal species today. When man’s exponential expansion began 500 years ago mammal extinctions were rare.

But in the past five centuries at least 80 of 5,570 mammal species have gone extinct, according to AFP.

While the number may not seem too large, it could signify the beginning of a larger trend in extinctions.
