Sylvia Earle on the Decline of Oceans
National Geographic Explorer in Residence Sylvia Earle discusses how oceans looked 60 years ago compared to now. "I tell people sometimes that I come from a different planet," said Earle. "Under the surface, much has changed in that time on the order of 90% of many of the big fish have been extracted from the sea."
