Normally when we think of refugees, we think of people who have lost their homeland by being forced to leave it. In the case of Vy Phalla, a Cambodian woman who lives by harvesting the aquatic life of her native mangrove forests, it is her land that has been forced away — literally. Singapore, to support its rapid land extension program, imports vast quantities of sand from Cambodia. Gone the sand, gone, too, the crabs and snails, shrimp and clams that Vy and her family depend on for their livelihood. And, gone the culture that she loves.
