Ten years on from landmark series Planet Earth, Sir David Attenborough returns with an equally stunning follow-up.

From islands to deserts, mountains to cities and grasslands to jungles, this six-part series explores how our planet has changed – and how developments in technology let us see it like never before.

We begin with a look at island life, from tiny uninhabited volcanic ones to mini-continents like Madagascar, home to more than 250,000 species.

Amazing sights include fighting Komodo dragons, a marching army of red crabs and a lovelorn sloth swimming in search of his mate – this is natural history TV at its very best.
