COMMENTS: SPANNING THE WORLD
Both ABC and NBC made use of others' resources to air fancy globetrotting to exotic locales. NBC aired an In Depth report from its London partner ITN: reporter Lawrence McGinty crawled inside a crevasse in Antarctica to explain how global warming climatologists extract ancient ice cores to trace fluctuations of carbon levels in the atmosphere. ABC's Ned Potter never left New York in his report on Dan Buettner of the Quest Network's Blue Zone, an anthropologist who studies those cultures where longevity is the norm. Courtesy of Quest, Potter showed us the vibrant elderly of Sardinia, Okinawa and Costa Rica.
