Tweet The global boom in sushi and overfishing have gone hand in hand for the last two decades. The tuna auctions, especially the Tsukiji in Tokyo, are a kind of Wall Street. There, each day, 2,000 tonnes of fish are sold, of which fifty of bluefin tuna are auctioned and sold at the price of gold. 80% of tuna caught and consumed in the world goes through Japan. Providing fresh seafood to industrialized countries has become a greedy business. Between 1995 and 2005, ten Mediterranean countries began to exploit their waters and soon after were joined by Japanese, Korean, Russian and South American fishermen. All the great powers of globalization overexploit bluefin tuna. The greatest damage occurred in 2007, when more than 60,000 tonnes were captured, twice the amount authorized. Powerful Japanese multinationals store stockpiles of millions of tons of bluefin tuna at sixty degrees below zero, a war chest with which to reap financial benefits in times of famine. The oceans are stretched to feed human greed, rather than hunger. Destructive trawling has depleted the stocks of the Mediterranean and Atlantic. With fish stocks weakened, Western fleets turn their gaze towards the African continent, which still has a rich marine biodiversity.

Are we the guardians of nature or simply tyrants? Why? Who will win when nothing remains? See more on BBC News SUBSCRIBE TO NEWSLETTER Thank you, your sign-up request was successful!
