Guardian Seascapes reporter Karen McVeigh tells Madeleine Finlay about a recent trip to the Galápagos Islands, where mounds of plastic waste are washing up and causing problems for endemic species. Tackling this kind of waste and the overproduction of plastic were the topics on the table in Ottawa this week, as countries met to negotiate a global plastics treaty. But is progress too slow to address this pervasive problem?. Help support our independent journalism at theguardian.com/sciencepod

Billed as a rival to the Olympic Games, the Enhanced Games, set to take place in 2025, is a sporting event with a difference; athletes will be allowed to dope.

What can sound tell us about nature loss? Guardian biodiversity reporter Phoebe Weston tells Madeleine Finlay about her visit to Monks Wood in Cambridgeshire, where ecologist Richard Broughton has witnessed the decline of the marsh tit population over 22 years, and has heard the impact on the wood’s soundscape. As species lose their habitats across the world, pioneering soundscape ecologist Bernie Krause has argued that if we listen closely, nature can tell us everything we need to know about our impact on the planet.
