National Geographic Channel’s groundbreaking series Great Migrations explores the massive movement of animal populations around the planet. The project chronicles these inspirational, often harrowing journeys that are marked by unforgiving odds, and what it means to move like your life depends on it. Wildebeests, zebras, red crabs, Mali elephants, walruses, monarch butterflies, jellyfish, and whale sharks will all be on display, and the production crew traveled some 420,000 miles, filming hundreds of stories in more than 20 countries. Using new science and technology, the series reveals how animals make death-defying journeys to survive. Great Migrations is the largest undertaking of its kind in the National Geographic Society's 120-year history. The seven-hour miniseries premieres globally in fall 2010. National Geographic's net proceeds support vital exploration, conservation, research, and education.
