Pearl divers in Cambodia. Young men there do this for tourists. In countries like Japan, pearl diving is seen as women's work. In places like the Philippines and Indonesia, it's the province of older men -- who have much greater stamina and lung capacity. But in Cambodia, which lost two-thirds of its population to genocide between 1975 and 1979, everything is the province of the young. Cambodia still has very few doctors, engineers, even teachers. Their educated youth leave the country for far better opportunities elsewhere. Tourism remains Cambodia's biggest industry, and tourists love to see "ethnic" activity like pearl diving, sponge diving, cliff diving, and similar activites. For poverty-stricken Cambodian youth, it's an easy way to make a living.
