Today's human beings not only play a decisive role in the energy flow, material circulation and information exchange between biological organisms in nature, but also have a remarkable influence on the geological cycle and composition structure in a wider range. As far as the ability of modern human beings is concerned, although it is impossible to affect the natural process and destroy the earth on a large time-space scale, it is enough to destroy various ecosystems on the earth, and it is also possible to introduce the relationship between man and nature into a new and higher level of harmony and stability.
If human beings destroy the ecosystem on the earth and the resource and environmental foundation on which human beings depend, it is self-destruction. The sustainable development of an important human and natural system depends on the soundness and rationality of each component in the system. For the prosperity and stability of the system between man and nature, the co-evolution between organisms in the system and between organisms and the environment is important. Only by co-evolution can we achieve sustainable development. Because of the special position of human beings in nature, the harmony and even co-evolution between human beings and nature are dominated by human beings. First of all, people should straighten their position, correctly understand the laws of nature, fully understand their own abilities and the positive and negative effects they may bring to nature, consciously adjust their relationship with nature, and take actions that conform to the laws of nature to make it harmonious and prosperous. This requires modern science to study not only nature, but also man and the relationship between man and nature.
In the traditional discipline division, the research purpose of natural science is to understand nature according to human needs and provide a basis for transforming nature to meet human needs. Whenever we make mistakes in the process of using nature due to one limitation or another, people often attribute the failure to the fact that human beings have no deep understanding of the laws of nature, and rarely check whether human needs exceed the tolerance and adaptability of nature. Of course, this is not to deny that human understanding of nature is far from enough. Social science, corresponding to natural science, aims to study how to transform society, but often ignores whether the evolution of human civilization is beyond the constraints stipulated by the co-evolution of man and nature. The relationship between man and nature is a proposition with extensive research connotation and evolving with development. Previous studies on philosophy, geography, sociology, history, anthropology, economics, ecology, etc. all involved a certain aspect of the relationship between man and nature from different angles and for different purposes, but in the rapidly changing global background, they could not solve the complex and acute contradiction between man and nature that mankind is facing at present. To accomplish new tasks in this new situation, we need new understanding and comprehensive research, make use of interdisciplinary advantages, grasp the various manifestations of the relationship between man and nature in different time and space, explore how to use human wisdom and initiative to make nature get rid of the slow spontaneous evolution process and quickly enter a dynamic equilibrium state, and at the same time pay attention to the regulation of human behavior, so that human beings can consciously adjust their own needs and values, constantly make up for the damage caused by mistakes, and adapt to the process of co-evolution.
In today's world, human beings have experienced the era of gathering and hunting that worships nature, the era of agriculture with natural advantages, and the era of plundering nature. At this moment, the relationship between man and nature is in deep crisis. Fortunately, human beings have begun to wake up and realize that only when people live in harmony with nature can they prosper. "If you don't remonstrate in the past, you can learn from those who know; It's not far from being lost. I don't think today is yesterday. "After the baptism of history, the relationship between man and nature will enter a new harmonious stage.
To sum up, man occupies a vital position in nature, and the core of solving the relationship between man and nature is the problem of man and cognition. The process of human transforming nature is the process of transforming itself. In any case, to realize the harmonious progress between man and nature requires the unremitting efforts of human beings and the interaction between theory and practice, which will be the common value choice and final destination for human beings to move towards sustainable development.
