> Although entropy must increase over time in an isolated or “closed” system, an “open” system can keep its entropy low — that is, divide energy unevenly among its atoms — by greatly increasing the entropy of its surroundings. Perhaps the Earth biosphere is the only "open" system in the Universe that keeps its entropy low by increasing the entropy of its surroundings, i.e. the rest of the Universe.
