Blue Planet reveals the Earth to us as only few people have ever seen it: from space.  Orbiting 200 miles above Earth's surface, we can see familiar landforms: the majestic Himalayas, giant Namib desert sand dunes, jewel-like Caribbean Islands.  From this unique vantage point we see how natural forces - volcanoes, earthquakes and hurricanes - affect our planet, and how a powerful new force - humankind - has begun to alter the face of the Earth.  From Amazon rain forests to Serengeti grasslands, Blue Planet inspires a new appreciation of life on Earth, our only home.
