Tour the mightiest mountain ranges, starting with the birth of a mountain at one of the lowest places on Earth and ending at the summit of Everest.
One of Earth's rarest phenomena is a lava lake that has been erupting for over 100 years. The same forces built the Simian Mountains where troops of gelada baboons live, nearly a thousand strong. In the Rockies, grizzlies build winter dens inside avalanche-prone slopes. The programme also brings us astounding images of a snow leopard hunting on the Pakistan peaks, a world first.
Planet Earth is a 2006 television series produced by the BBC Natural History Unit. Five years in the making, it was the most expensive nature documentary series ever commissioned by the BBC and was described by its makers as 'the definitive look at the diversity of our planet'.
Each 50 minute episode features a global overview of a different biome or habitat on Earth, followed by a ten-minute featurette which takes a behind-the-scenes look.
