Sand isn't just for beaches. The tiny grains show up in many products of the industrialized world: in the glass and concrete that build cities, in detergents and cosmetics that people use daily, and in the silicon chips and solar panels of advanced technology. But sand comes from rocks that take thousands of years to erode into fine particles, and humans are using it faster than they should, reports Autumn Spanne for Mental Floss. The clamor for sand is so great in fact, that organized crime has sprung up around sand mining. On the fringes of Bannerghatta National Park in southern India, trucks filled with sand mined near the protected forest attempt to sneak their loads past officials in the dead of night.
