      And at this point, you’re probably thinking — What about the deserts? Aren’t those vast swathes of land covered in sand? Well, they are. But you can’t use them. They’re the wrong shape. They are too smooth, too round and they don’t lock in and bind together easily. So you can’t use them in asphalt and concrete. The sand we need ought to be angular. It has to have variety in size. You find these along the seabed, coastlines, quarries and river banks— usually protected areas.
