The Charcoal People (2000)

This deeply human documentary examines the subject of environmental destruction, highlighting the impoverished migrant workers who are chopping down the Amazon rainforest to create charcoal for pig iron production used primarily in the automobile industry. The film examines the children and elders and their daily lives and work as they burn timber in igloo-looking huts, their bodies charred gray for $2 a day, struggling to survive.

Unfortunately the movie The Charcoal People is not yet available on HBO Max.
