In the final analysis, human protection of the environment is based on the protection of the increasingly depleted resources on the earth, and the protection of water resources is the most basic condition for human survival and development.

First of all, we should establish the consciousness of cherishing water and carry out water resources warning education. For a long time, most people generally believe that water is an inexhaustible "cornucopia", which is wasted in use and does not know how to cherish it consciously. In fact, the water resources on the earth are not inexhaustible. Especially in China, the per capita water resources are not rich, the regional distribution is uneven, and the year is unpredictable, with great inter-annual differences. Coupled with serious pollution, water resources are even more scarce, which is vividly reflected in the repeated water cuts of the Yellow River. National water resources utilization projects such as "Yellow River Diversion Project" and "South-to-North Water Transfer Project" are aimed at solving the water shortage problem in some areas, but we should think deeply: Where can we "divert water from the Yellow River" when the water in the Yellow River is exhausted? The water in the south is polluted. How to "transfer water to the north"? Therefore, people must establish the consciousness of water crisis, take saving water resources as our conscious code of conduct, and carry out water resources warning education in various forms.
