A unique testimony from a unique broadcaster.

Sir David Attenborough revisits his award-winning shows, shares anecdotes from an astonishing career spanning 60 years, returns to the Borneo jungle as he tracks a lifetime of developments in filming technology and scientific discovery and explores the ever-growing plight of the natural environment.

Through such acclaimed series as Life on Earth, The Private Life of Plants, Life in Cold Blood and Frozen Planet, Sir David Attenborough has been at the forefront of natural history film making for over half a century, witnessing an unparalleled period of change in our planet's history.

In this unique and important series Sir David delivers his testimony in a trio of spectacular films, focusing on the three areas which have transformed most profoundly over his career. He charts the development of natural history programme-making from the early TV cameras used for Zoo Quest in 1956 to the latest high-definition and micro-camera technology. He considers the rapid advances in science —from discoveries about the structure of DNA to a better understanding of continental drift and he lays bare the potentially devastating environmental consequences of the planet's rapid economic and population growth.
