Episode 377 For the first time, scientists have mapped Earth’s vast underground fungal network - and it’s bigger than anyone imagined. Beneath our feet, plants and fungi have a hidden symbiotic relationship, sharing nutrients through fine fungal threads called hyphae. With these new global maps, we’re now starting to understand just how important the mycorrhizal network is in keeping the Earth’s climate stable - including the extent of the carbon it draws down. But the ecosystems where these networks exist are being stripped back for agriculture and damaged by fungicides - so how can we protect them? To explore this topic, Rowan Hooper is joined by some of the researchers behind the project - Toby Kiers, Tom Shimizu and Merlin Sheldrake.
