Sir David Attenborough - WWF at 50

Sir David Attenborough reflects on the early days of conservation and more specifically the work of Peter Scott, who was instrumental in the formation of WWF - the World Wide Fund for Nature.

He talks about the issues facing environmental organisations today and speaks passionately about the need for conservation groups such as WWF.

On a lighter note he touches on his career in the broadcast industry and the love he holds for the natural world.
