Sand is hard at work creating dream homes, dream vacations and everything else in between.
With such high demand, sand is becoming increasingly scarce in many regions.
Now, not all sand is created equal. Desert sand is largely useless to us. The bulk of the sand we harvest goes to make concrete, and for that purpose, desert sand grains are the wrong shape.
The sand we need is more angular and found in the beds, banks, and floodplains of rivers, as well as in lakes and on the seashore.
