Sir David Attenborough has witnessed an unparalleled period of change in our planet’s history. Now he looks back over the past 60 years in a very personal film in which he reflects on the dramatic impact that we have had on the natural world during his lifetime. He returns to the jungles of Borneo, to the London Zoo and to Peter Scott’s home at Slimbridge, important places in the development of his attitude towards nature. And he reviews rare footage from his early days in television and his own photos, showing classic encounters with orangutans, whales, and the giant Galapagos tortoise, Lonesome George. Produced by Susie Painter, BBC Natural History Unit.
