The Moken, a nomadic sea tribe living in the Andaman Sea off the coast of Thailand and Myanmar, face an uncertain future. Their traditional, aquatic lifestyle is untenable in the face of climate change, tourism, fishing restrictions and natural disasters. Forced to settle on land, some have turned to an unlikely income source: plastic washed ashore on the remote islands they now call home. The plastic has become more reliable than the fish they used to catch, but many see it as a means to pass their traditional knowledge down to the next generation.
