Like any other creature, a society eats. We call this "consumption", as if it is somehow different by nature. But the techniques we use so often reflect that of a single creature. This quarry has been stripped layer by layer, just as we strip an apple of its' flesh through a series of progressively deeper bites...
Dynamite or rock cutters push apart the rock from body of the hill with forces similar to those that are produced by the wedge shape of our front teeth. We grind these chunks of food with molars not dissimilar to the rock crushers found at most mines. We often put this rock through a series of water-rich chemical processes to purify a valuable material within, just as our saliva and digestive juices break down our food into usable material. The bi-product, whether through a refinery or a digestive tract, is an undesirable material to either.
