Note: The rule of entropy means that to takes energy and effort to create order from disorder. But the rules of the universe tends to maximize disorder which is the equilibrium state. This means that order is a high energy state that decays effortlessly to disorder which is the equilibrium state. The energy released from dissembling order can be used. Animals feed on negative entropy, extracting energy by converting organic molecules (order) into carbon dioxide and water (disorder). Plants extract energy from sunlight and use it to synthesise carbohydrates and other organic molecules (imparting order) from carbon dioxide, oxygen and water (disorder). Decay is inevitable, and unstoppable. Much of our effort to build and sustain order is inevitably wasted.
