Admiral defends Navy's use of sonar, says threat to whales is unsubstantiated

In late 2005, the Natural Resources Defense Council along with several other environmental groups filed a lawsuit against the Navy, claiming that its use of sonar was harming marine mammals. A recent federal court ruling ordered the Navy to restrict its use of mid-frequency sonar in order to protect marine mammals. During today's OnPoint, Rear Admiral Lawrence Rice, director of the Navy's Environmental Readiness Division explains why he believes the environmental groups' claims are unsubstantiated. He explains why the Navy needs to use sonar, citing national security as a concern if sonar use is scaled back.
