Human history is a history of continuous reconstruction. Regardless of whether technology is backward or advanced, human beings' ability to control natural forces always has its limits, and the occurrence of the end of the law era has its inevitability. For example, land, which used to be the god that gave birth to us and our home, has only become a mineral deposit that can be mined by anyone under the vision of technology. Now, we need to add a piece of land, which has become a land parcel for real estate development. For example, livestock, cattle, and sheep, which were originally independent creatures and have long been companions of humans, have now only become raw materials for food factories. For example, rivers were originally natural landscapes and the cradle of nations. All major civilizations originated from these rivers, but now they have only become suppliers of water pressure for power generation. When people build power plants on large rivers, they actually turn them into a component of the power plant, and as a result, the rivers lose their basic existence of complex ecology.
