(Newser) – Humanity's impact on the planet over the last 200 years has been so vast that geologists are proposing to label it the start of a new geological era, reports.

"We are now living in a new time period when the human modification of the system is so great that we need some way of recognizing that," said a member of a growing group of geologists calling for the present era to be labeled the "Anthropocene age." He said geologists could date it from carbon dioxide deposits—or the lingering radioactivity from the first nuclear tests. (Read more geology stories.)
