Sixth mass extinction is underway

Sydney: The world is experiencing a “biological annihilation” of its animal species due to “human-caused global environmental problems” in recent decades, a new scientific study has found.

The demise of billions of animals from thousands of species both rare and common means the sixth mass extinction event is already well underway and is “more severe than perceived”, the study published in a peer-reviewed journal, Proceedings of the National Academy of Sciences (PNAS), said.
