For decades Sir David Attenborough has brought the natural world into people’s homes. But his upcoming film, “A Life On Our Planet”, offers a stark message about human impact on the environment. Anne McElvoy asks the godfather of natural history television where he draws the line between wonder and warning. Does his work have the power to change hearts and minds or is he preaching to the choir? They talk about whether the climate could be the only winner from the global covid-19 pandemic and why he has stopped trying to get through to President Trump. Plus, a knock at the door and an unexpected question.

“David Attenborough: A Life on our Planet” will be released in cinemas and on Netflix later this year. Please subscribe to The Economist for full access to print, digital and audio editions: economist.com/radiooffer
