It was once a "foolish" notion, largely written off as an old wives' tale: that animals can sense impending natural disasters.
But today, given potent impetus from events preceding last winter's catastrophic tsunami, it's attracting serious scientific attention around the world as an idea that someday may help save human lives. Thirteen/WNET New York's NATURE series travels to four continents to examine this provocative and intriguing subject in CAN ANIMALS PREDICT DISASTER? - airing Sunday, May 13 at 8 p.m. (ET) on PBS (check local listings).
