Sir David Attenborough and his captivating programmes about the natural world, for many people - myself included, have always been there. My first recollections of his work are Sunday evenings in front of the television watching The Living Planet - the accompanying book still sits on my book-shelves. Life On Air provides an insight on the 30 years experience that were used to make that programme, and all the others that I have watched since, so great. What is lovely about the narration is that you get the impression that Sir David not only wants to make the programmes, he almost "has too". His desire to capture on film as many aspects of the planet earth is all consuming, and this is probably why his programmes remain so popular today.
