The guna or kuna, an indigenous people of Panama, suffer from the same waste problems as the rest of the world, with the added complications caused by life on tiny, crowded coral islands. The Guna, originally mainland dwellers, moved offshore in the 19th century, thus escaping mosquitoes, snakes, and the diseases spread by mosquitoes while facilitating access to foreign trading boats. Today, of the forty-nine villages in the autonomous indigenous reserve called Guna Yala, all but ten are located on islands along the northeast Caribbean coast, with populations ranging in size from a few hundred to several thousand.
