A Penan mother and child in the forest, Sarawak, Malaysia. Whilet many are settled in communities, the tribe is traditionally nomadic and many rely on the forest for their existence. However, their way of life is increasingly under threat from large-scale commercial logging. Photograph: Robin Hanbury-Tenison/Survival
