Neighbor Leaves Singapore Short of Sand - New York Times
International politics aside, Singapore needs sand and they are going to by it. Granted, Singapore needs to import theirs and most developing countries can supply their own. Worth consider the skyrocketing demands of steel and sand. Such commodities, like energy, are such that the market is going to increase their price. Hard to find the consumer monopoly, but worth investigating forging infrastructure/cement companies that are supplying sand to Singapore, Shanghai, etc. Figure Dubai is doing OK on sand.
