Living things and their environment form an ecosystem. This kind of system, relying on the exchange of energy and material with the outside world, maintains its own structure and function. The energy conversion and material circulation of an ecosystem have a certain order and limit in quantity, position and order, which conforms to this order and promotes a certain limit, and the structure and function of the system are in a stable state, that is, the so-called ecological balance.
In the natural ecosystem without human intervention, natural forces may also destroy the ecological balance, but coordination and balance can usually be restored through the self-regulation of the ecosystem. The appearance of human beings has added a new member to the biosphere. As a product of biological evolution, human beings have not lost their biological attributes. From this perspective, human beings are an integral part of the natural ecosystem.
However, people are different from ordinary creatures. The sociality of man makes the power of man as a biological individual become the social power of man. In order to meet the needs of survival and development, human beings have gradually changed from accepting the gift of nature to conquering nature, which has led to profound changes in the ecosystem. The human-centered ecological environment is not the original ecological environment, but the social ecological environment that has been artificially transformed.
