Geologists have knocked down the Anthropocene, a concept necessary to define what we are doing to the Earth. The impacts of humanity now rival the great forces such as volcanism, erosion or plate tectonics.

We are accelerating a new mass extinction of species recorded on the planet. The Sixth Extinction is also the title of the book that popularized this catastrophic event.
