Sushi, anyone?

Sushi restaurants around the world have driven the Bluefin Tuna to the brink of extinction.
15,000 tons is the limit that can be fished without without the species becoming extinct.
Last year's global sales reached an estimated 61,000 tons of bluefin tuna.

clipped from www.time.com The surge in bluefin tuna fishing over the past decade has been driven by the proliferation of sushi restaurants across the world. The bluefin industry, once the province of rustic local fishing fleets in Mediterranean, was last year worth about $1.6 billion. Today, tuna fleets use high-tech spotter planes buzzing over the Med during the summertime tuna-spawning season, in search of shoals that have escaped the trappers. The industry's major players are massive multinational corporations such as Mitsubishi, the world's biggest tuna trader — Japan imports the bulk of bluefin tuna caught in the Med. Some of the larger companies have created state-of-the-art tuna ranches in the Med's deep waters, where bluefin tuna swim into giant nets and are fattened over a period of months before being hauled out and processed in floating factories before being exported.
