Man is a pest
Big Bang, as he was fondly called, once decided to make a time piece. A time piece - he would make just once and will run forever without any intervention. He designed the time-piece as self correcting as possible and vowed to not touch the system after it is made.
Being a connoisseur of art, he created several spherical objects and kept them such that the force between them kept them "stable" as well as in motion. They repeated their motions after specific periods. It was a pretty complex time-piece as it contained hundreds of particles - each with its own motion and time period.
Big Bang painted one object with utmost interest. He painted 70% of it blue and 30% of it green. He, then, added texture to the surface. There were areas that were higher and rocky while others that were plain.
Slowly and steadily the termites started increasing their colony on this most favorite object of Big Bang. They had their king and queen termites along with worker and soldier termites. Worker termites undertake the labors of foraging, food storage, brood and nest maintenance. The soldier caste has anatomical and behavioral specializations, providing strength and armor. Many soldiers have jaws so enlarged that they cannot feed themselves, but instead, are fed by the workers. [Source]
Soon, their nests started reaching above ground forming what is called mounds or anthills. In certain areas the mounds became very high. Then, there started a crazy competition among the different colonies of termites to create the tallest of mounds. The termites eventually forgot the purpose of creating mounds and started digging into the surface of the-once-upon-a-time-beautiful object. They started making the object weaker and weaker. A few, too few, worker termites realized that making such insanely high rise mounds is only going to bite them back. They tried convincing others. But the kings, the queens and the soldiers didn't listen to them. Other worker termites were too busy doing their daily chores to even think of long term repercussion of the high rise mounds.
Eventually, the object that Bing Bang had created with immense love and affection was dotted with high-rise mounds. The balance that the object was to maintained changed slightly - though not significant enough for the termites to perceive. The termites kept eating their own 'home'.
Big Bang helplessly watched his most favorite object in the time-piece rot.
