A mass extinction is defined when Earth loses more than three quarters of its total estimated species in a geologically short timeframe. The planet has experienced five such events over its ~4.5 billion year history, with causes thought to include meteor collisions, massive volcanic eruptions and sudden climate fluctuations. Now a growing body of evidence suggests that mankind itself may be responsible for a mass extinction to rival all others, now well underway.

Prof Mike Coffin, Executive Director of the Institute for Marine and Antarctic Studies at the University of Tasmania, is an oceanographer. His research expertise encompasses interactions between the oceanic environment and the solid Earth. Educated at Dartmouth College (AB) and Columbia University (MA, MPhil, PhD) in the United States, he has pursued an international career that reflects the boundless nature of the global ocean.

Prof Coffin has lead or participated in 29 blue-water research expeditions at sea, focusing mainly in the Southern, Pacific, and Indian oceans.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
