In the long run, what is the way to solve the problem of water resources utilization?

If the spatial distribution is uneven-inter-basin water transfer; Such as the South-to-North Water Diversion Project and Luanhe River Diversion Project; If the time distribution is uneven, then build reservoirs: the Three Gorges Project and Gezhouba Project all manage the water flow in the Yangtze River basin, and the Xiaolangdi Project manages the water flow in the Yellow River basin. There are many ways to solve the problem of water resources in daily life, such as saving water (multiple uses of one water), preventing water pollution (stopping the discharge of factory and domestic wastewater), and solving the problems of waste and water pollution. Don't waste water resources here! (World Water Day: March 22nd)
