Grasslands cover one quarter of all land and support the vast gatherings of wildlife, but to survive here animals must endure the most hostile seasonal changes on the planet. From Asia's bizarre-looking Saiga antelope to the giant anteaters of Brazil, grassland animals have adapted in extraordinary ways to cope with these extremes. In the flooded Okavango, lions take on formidable buffalo in epic battles, on the savannah bee-eaters take advantage of elephants to help catch insects and, on the freezing northern tundra, caribou embark on great migrations shadowed by hungry Arctic wolves.

The proverbial musical chameleon, Duncan Browne recorded the post-psych chamber pop classic Give Me, Take You album in 1968 before re-emerging four years later with the introspective singer/songwriter hit single 'Journey'. By the mid-1970s, he had signed to the Transatlantic label as a member of Euro art rock sophisticates Metro, a trio whose calling card, 'Criminal World', was covered by David Bowie on his 1983 album Let's Dance, which went on to sell over ten million copies.

This landmark series uses specialist imaging and compelling narrative to tell the life story of our planet, how it works, and what makes it so special. 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. This is a series that shows the Earth in new and surprising ways. Extensive use of satellite imagery reveals new views of our planet, while timelapse filmed over many months brings the planet to life. Offering a balance between dramatic visuals and illuminating facts, this ground-breaking series makes global science truly compelling.
