Nature is generous, and harmony between heaven and earth is the ultimate goal. In the future society, human beings should actively, consciously and actively protect nature and maintain the natural ecological balance, because man is only a part of nature, after all, it is not "man can conquer nature". Humans can fully understand nature, make rational use of nature and strive to transform nature according to its laws, but they can never conquer nature. China has established a legal basis for water environmental protection, but these measures are far from enough, and the situation facing environmental protection is quite grim. There are still many things we need to do in the future.
