Climate change is making weather more extreme and threatening crops and wildlife. But could old solutions help us tackle these challenges? Around the world, farmers and scientists are reviving ancient crops, and reintroducing ancient animals to build resilience against climate impacts.

In this episode, reporter Beth Timmins travels to the Peruvian Andes to meet the ‘Potato Guardians’, while Jordan Dunbar visits London’s Natural History Museum. Curator Lottie Dodwell-Williams introduces the museum's first climate-focused exhibit, Fixing Our Broken Planet, which includes a plan to bring bison back to Britain.

Host Graihagh Jackson chats to Jordan and Beth about how traditional knowledge and techniques from the past are being used to combat the effects of climate change today.
