National Geographic : 1997 Dec
sanctuary National Geographic and National Public Radio present Frontiersin the Sea, a special digital stereo production in December of RADIO EXPEDITIONS, the acclaimed series hosted by Alex Chadwick. Overuse and pollution threaten our once pristine underwater frontiers, including the crown jewels of our coastlines, the living coral reefs. As we mark the 25th anniversary of the National Marine Sanctuaries system, will we show as much determination to save these submerged kingdoms as we have our national parks? Call your local NPR station for times. NATIOa NATIONAL iO GEOGRAPHIC F o d National Public Radio and National Geographic thank the David and Lucile Packard Foundation and the Curtis and Edith Munson Foundation for their generous support of Frontiers in the Sea.
