We use 50 billion tons of sand a year.
"The sand we need is the more angular stuff found in the beds, banks, and floodplains of rivers .... The demand for that material is so intense that around the world, riverbeds and beaches are being stripped bare, and farmlands and forests torn up to get at the precious grains.
