The world is experiencing a “biological annihilation” of its animal species because of humans’ effect on the Earth, a new study has found.
Researchers mapped 27,600 species of birds, amphibians, mammals and reptiles — nearly half of known terrestrial vertebrate species — and concluded the planet’s sixth mass extinction even was much worse than previously thought.

"There are examples of species all over the world that are essentially the walking dead," said Stanford University Professor Paul Ehrlich. "We are sawing off the limb that we are sitting on."

Three U.S. universities have issued a report warning that the Earth has entered a new period of extinction. The study by the universities of Stanford, Princeton and Berkeley stated that vertebrates were disappearing at a rate 114 times faster than normals and conclude that humans could be among the first casualties.
