Humans are disrupting natural 'salt cycle' on
A new paper in the journal Nature Reviews Earth & Environment revealed that human activities are making Earth’s air, soil and freshwater saltier, which could pose an “existential threat” if current trends continue. Geologic and hydrologic processes bring salts to Earth’s surface over time, but human activities such as mining and land development are rapidly accelerating this natural “salt cycle.”
