There's some new analysis of the global trade in sharks, driven largely by the demand for shark fins and centered in Hong Kong, that shows the UN Food and Agriculture Organization may be greatly underestimating the number of sharks killed annually.
According to Pew Environment Group, 3-4 times as many sharks are being caught each year as are shown in UN FAO stats.
The study shows that Hong Kong is responsible for 50% of all trade in shark fins, with 83 countries sending some 22.7 million pounds of shark fin products there last year.
