Biodiversity talks enter final day

Talks in Geneva to reverse the loss of nature and halt extinctions are in their final day. We'll hear from Patrick Greenfield, biodiversity reporter for the Guardian, on the details of the negotiations, and Dr Noelle Kumpel, head of policy for Birdlife International, about her thoughts on the progress. Also in the programme, the war in Ukraine is halting moves aimed at limiting the use of palm oil, which is a cause of deforestation in Asia. The price of one alternative, sunflower oil, has increased massively since the conflict began, and supermarket chain Iceland has reversed its pledge to remove palm oil from its own-label food. We find out more from Glenn Hurowitz of the Washington DC campaign group, Mighty Earth. Plus, the BBC's Jo Critcher reports on how drones are now being used all over the world for humanitarian purposes.
