The Living Planet: A Portrait of the Earth is a BBC nature documentary series written and presented by David Attenborough, first transmitted in the UK from 19 January 1984. The sequel to his pioneering Life on Earth, it is a study of the ways in which living organisms, including humans, adapt to their surroundings. Each of the twelve 55-minute episodes (one fewer than his previous series) featured a different environment. The executive producer was Richard Brock and the music was composed by Elizabeth Parker of the BBC Radiophonic Workshop.
