Someday soon, you might be finally able to count all the grains of sand on the beach, because there might be no beaches—and no sand—left. With the global population and its attendant consumption booming, we’re running out of sand in our quest to build larger cities and better smartphones. This essential resource, so easy to overlook, ranks just below air and water on a global scale of how much we use.
