The Obama administration is proposing to allow the Navy to harm more than 30 million marine mammals while conducting exercises in two training ranges over the next five years. Under two proposed rules to be published in Thursday's Federal Register, the National Marine Fisheries Service would allow the Navy to kill, injure or disrupt the behavior of whales, dolphins and other marine mammals 9.6 million times in the Hawaii and Southern California training ranges and 21.8 million times in the Atlantic training range over a five-year period beginning in January 2014.
