Turtle excluder device

The World Trade Organization settles disputes among nations when their individual trade laws conflict. There are complaints that international trade is winning out over the environment in some of the decisions. For example, it ruled in 1998 that a U. S. law requiring turtle excluder devices to protect endangered species of sea turtles from being trapped in the nets of shrimp fishermen was really a trade barrier and need not be enforced.63... 

Federal law requires that shrimpers use turtle excluder devices (TEDs) on their nets in order to protect sea turdes. When a turde gets caught, the net opens up and allows the turde to swim free. Sciendsts tracking killer whales have learned that some groups stay within a local area, feeding on salmon and other fish, while others wander the oceans hunting for seals.
