First, make rational use of science and technology and respect the laws of nature. I don't need to repeat the function of science and technology, but how to make good use of it, especially how to use it to guide the relationship between man and nature into a benign direction is more important. For example, to strengthen the study of eco-environment science, since science and technology have been very developed, it is necessary to make use of these advantages to do in-depth study of eco-environment science and other aspects, to explore more laws of nature, to make use of these explored natural laws, and to try to explore more effective ways to repair existing ecological problems.
