Consumer taste and prices can also have harmful effects

Consumer taste and prices can also have harmful effects.For example, shark fin soup is considered such a delicacy in China and Vietnam that the fin has become the most profitable part of the shark.This leads many fishermen to fill their boats with fins leaving millions of dead sharks behind.The problems aren't unique to toothfish and sharks.Almost 31% of the world's fish populations are overfished,and another 58% are fished at the maximum sustainable level.Wild fish simply can't reproduce as fast as 7 billion people can eat them.
