Earth: The Power of the Planet (2007)
Examining the great forces that shape the Earth - volcanoes, the ocean, the atmosphere and ice - the programme explores their central roles in our planet's story. How do these forces affect the Earth's landscape, its climate, and its history? CGI gives the audience a ringside seat at these great events, while the final episode brings together all the themes of the series and argues that Earth is an exceptionally rare kind of planet - giving us a special responsibility to look after our unique world.
