Spoiler alert: Stop reading now if you can't live without Quarter Pounders, packaged pastries, or expensive sushi. —Avital Andrews
We'll let Pulitzer Prize–winning food critic Jonathan Gold get on his soapbox for this one: "People need to stop eating BLUEFIN TUNA. Period. It'll be difficult because bluefin is uncommonly delicious and tends to be served at high-end sushi bars, where the fashion is to say 'omakase' and submit to the chef's will. But the numbers of these magnificent fish are dropping fast. If we don't stop eating them now, we'll stop in a few years anyway because there won't be any more." Carl Safina, who founded the Blue Ocean Institute, adds, "Because they're long-lived, bluefin populations don't stand up well to heavy fishing pressure—that's why they're so depleted. It's just too sad to eat them. Plus, big fish are high in mercury." To rein in your share of the overfishing disaster currently unfolding—bluefin stock is down by more than 96 percent from unfished levels—order a vegetarian roll instead.
