Brief introduction of ecological environment
Ecosystem refers to a unified whole composed of biological community and inorganic environment. The range of ecosystems can be large or small, and they are intertwined. The largest ecosystem is the biosphere. The most complex ecosystem is the tropical rain forest ecosystem, and human beings mainly live in artificial ecosystems dominated by cities and farmland.
Ecosystem is an open system. In order to maintain its own stability, the ecosystem needs to continuously input energy, otherwise it is in danger of collapse. Many basic substances are constantly circulating in the ecosystem, among which carbon cycle is closely related to the global greenhouse effect. Ecosystem is the main structure and functional unit in the field of ecology, which belongs to the highest level of ecological research.
With the improvement of productivity, the interference of human activities on the ecosystem is increasing. In the pain of destruction and protection, life and money, human beings gradually realized the true value of the ecosystem, began to pay attention to the current situation of the ecosystem, and brought it into the ethical system, forming a brand-new ecological ethics, which profoundly affected the huge industrial empire and the ultimate fate of mankind.
