A handout photo provided on May 2, 2011 by the Pew Environment Group and taken on June 20, 2009 shows a diver looking at five reef sharks off the coast of the Pacific island nation of Palau.

The analysis from the Pacific island nation of Palau shows that sharks — hunted worldwide for their fins, a Chinese delicacy — are worth many times more to some local economies alive than dead.
