S9·E57 Salt Mines
Synopsis
It’s the only rock we eat – a priceless commodity essential to our very survival. It has over 14,000 uses – from de-icing our roads to softening our water. We dynamite it from vast caverns deep beneath the earth’s surface, harvest it via solar evaporation from seawater ponds, and mine it with huge hydraulic pipes penetrating to subterranean deposits. The world of salt…something to think about the next time you sprinkle that humble white crystal over your next meal.
