TV presenter Sir David Attenborough has praised conservationist Dame Jane Goodall as a “tireless advocate” for chimpanzees and a “great champion of environmental protection” following her death aged 91. The conservationist, who was the world’s leading expert on chimpanzee behaviour, died from “natural causes” in California, The Jane Goodall Institute said in a statement on Wednesday. He said “we all must carry the torch” for Dame Jane” and protect “our one shared home”, in a post to Instagram on Wednesday. “Jane Goodall devoted her life to protecting our planet and giving a voice to the wild animals and the ecosystems they inhabit. In another tribute, Greenpeace’s co-executive director in the UK, Will McCallum, said Dame Jane “was one of the true conservation giants of our time”.
