We have celebrated the land and the seas with Planet Earth and Blue Planet; now its about time that we turn an eye to the fascinating cultures that share space on our rock in the sky. These cultures are disappearing at the same rate that the wonderful and rare animals are, so it is great that BBC decided to record them too.
The above links to an audio slideshow made by a photographer who accompanied the filmmakers/ http://www.bbc.co.uk/news/world-12618167. Below is the BBC trailer.
