Resource poetry

Water, you are the blood of the earth. Without you, there would be no life on the earth. Water, you are the lifeblood of the earth. Without you, there would be no human beings on the earth. Everyone must save water. Water resources on the earth, in a broad sense, refers to the total amount of water in the hydrosphere. Including surface water and groundwater which can be directly used for irrigation, power generation, water supply, shipping and aquaculture, as well as rivers, lakes, wells, springs, tides, harbors and aquaculture waters. In a narrow sense, it refers to the amount of fresh water that can be restored and updated every year. Water resources are indispensable and important natural resources for the development of national economy. In many parts of the world, the demand for water has exceeded the capacity of water resources, and at the same time, many areas are on the verge of unbalanced utilization of water resources, so we should cherish water resources.
