Perfect Planet takes a fresh look at Life on Earth. By combining a global view of the planet with intimate animal stories it will reveal our world as never before. Using state of the art satellite imagery and technology, it shows how the seasons drive both our global weather patterns and ocean currents, and how this supports the planet's incredible diversity of plants and animals. The series also reveals those moments when the perfect planet doesn't seem so perfect. Forces of nature such as hurricanes, earthquakes, fire and volcanoes can wipe out life in an instant, but without them Earth would slowly waste away. These natural disasters are actually the lifeblood of the planet. Some plants and animals even depend on them for survival.
