Boris Worm, a marine biologist at Dalhousie University in Canada, made a startling prediction in the pages of Science in 2006: if overfishing continued at then-current rates, he said, the world would essentially run out of seafood by 2048. Worm’s bold analysis whipped up controversy in the usually pacific world of marine science — one colleague, Ray Hilborn of the University of Washington, called the Science study “mindbogglingly stupid.” But Worm held fast to his predictions: that the oceans had limits, and that marine species were declining so fast that they would eventually disappear.
