"Entropy is a measure of disorder. And there are always far more disorderly variations than orderly ones. Here's the crucial thing about entropy: it always increases over time. It is the natural tendency of things to lose order. Left to its own devices, life will always become less structured. Sand castles get washed away. Weeds overtake gardens. Ancient ruins crumble. Cars begin to rust. People gradually age. With enough time, even mountains erode and their precise edges become rounded. The inevitable trend is that things become less organized. This is known as the Second Law of Thermodynamics. It is one of the foundational concepts of chemistry and it is one of the fundamental laws of our universe. The Second Law of Thermodynamics states that the entropy of a closed system will never decrease. " - Wikipedia
