Fears are growing for an isolated tribe in Indonesia, as the country pushes ahead with a massive project to produce nickel for electric car batteries, which will affect the Hongana Manyawa peoples' habitat.

The Hongana Manyawa – a name which means "People of the Forest" in their own language - are one of the last nomadic hunter gatherer tribes in Indonesia.

The Indonesian government, though, aspires to become a major producer of the metal as countries ditch fossil fuel-powered vehicles for electric ones, and is set to expand its large-scale mining and production operations in order to do so.

On the programme we heard from Callum Russell, who works for the right's group, Survival International.
