Jane Goodall, the famous primatologist, has set us a challenge: Is it possible to tackle climate change whilst also lifting people out of extreme poverty?
Her question - posed to the BBC's Climate Editor Justin Rowlatt - is inspired by her own experience of tackling deforestation in Tanzania. As her colleague Emmanuel Mtiti explains, they convinced local villagers to stop felling trees, and to restore the natural habitat of chimpanzees, by offering them an alternative path to prosperity.
So could an equivalent path be available that avoids increasing carbon emissions? If so then it would break with the pattern seen in Europe, America and China, where economic development was almost entirely fuelled by burning coal, oil and gas, according to Hannah Ritchie, head of research at Oxford University's Our World in Data team. But the micro-finance pioneer Muhamad Yunus says that solar power does now offer a carbon-free way forwards.
The programme contains audio from the 1965 National Geographic documentary film Miss Goodall and the Wild Chimpanzees, as well as audio recorded at Gombe National Park and the surrounding area by Ruth Happel and Bernie Krause.
