At present, the amount of sand being mined, particularly in Asia, is unsustainable, considering that weathering of rock to sand particles—ranging in size from 63 micrometers to 2 millimeters in diameter—takes hundreds of thousands of years, or longer. Vietnam, for example, expects it may run out of sand by 2020. Supply aside, the environmental cost (impact) of sand mining may be even greater.
