How Many Lightbulbs Does It Take to Change a Planet? by Tony Juniper

He was later Campaigns Director and played a prominent role in campaigns on GM crops, world trade, transport and industrial pollution. He later led Friends of the Earth's work on biodiversity and chaired a multi-organisation campaign that resulted in the 2000 Countryside and Rights of Way Act. Juniper joined Friends of the Earth in 1990 to lead the organisation's tropical rainforest campaign. His book 'Parrots of the World' (co-authored with Mike Parr) was awarded Reference Book of the Year by the UK Library Association in 1999. The story of the Spix's Macaw was adapted to form the basic plot to the film Rio. In his book Spix's Macaw: The Race to Save the World's Rarest Bird he criticised private holders of birds such as Antonio de Dios's Birds International, arguing that the Spix's macaws should be returned to their native country, Brazil, for captive breeding and reintroduction to their natural habitat, which is still in decline. He was for example involved in efforts to save the Spix's macaw, one of the most endangered birds in the world. Juniper is a recognised authority on parrots, having worked at BirdLife International on efforts to conserve rare species of these birds. In 2016 Juniper was declared as a Harmony Professor of Practice with the University of Wales Trinity St David. In 2013 he was awarded honorary Doctor of Science degrees by the University of Bristol and the University of Plymouth.

He became a Senior Associate and later a Fellow with the Cambridge Institute for Sustainability Leadership, based at the University of Cambridge. Raised in Oxford, Juniper attended Bristol University, taking a joint honours BSc in psychology and zoology in 1983, followed by a master's degree in conservation from University College, London in 1988. In 2019 he was appointed chairman of Natural England. He was the Green Party's parliamentary candidate for the Cambridge constituency at the 2010 general election. He was Vice Chair of Friends of the Earth International from 2000 to 2008.
