OVERFISHED SUSTAINABLE

摘要

Last May, I visited a sushi restaurant in Manhattan with Sergios-Orestis Kolokotronis, a biologist at the American Museum of Natural History, to learn what scientists can do to protect endangered animals-in this case, bluefin tuna. Some species of bluefin have been fished to near extinction, and manysushi restaurants still serve those species, but on the day of our visit the menu identified the neat rectangles on our plate-trimmed of eyes, skin and other identifying features-simply as "tuna," "fatty tuna" or "medium fatty tuna."
