Earth's Sixth Mass Extinction Coming?
Mankind may have unleashed the sixth known mass extinction in Earth's history, according to a paper released by the science journal Nature.
But in the last five centuries, at least 80 out of 5,570 mammal species have bitten the dust, providing a clear warning of the peril to biodiversity. What these frog scientists might have missed?
