What methods will you take to make the tropical rain forest sustainable? Of course, the sustainable development of trees (people should cooperate and don't destroy the environment) or sustainable development (Dé development) refers to a development model that not only meets the needs of contemporary people, but also does not harm the needs of future generations. Definition of sustainable development: Sustainable development originated from the Green Movement in 1960s, when developed countries bought a lot of agricultural land in Africa and South America to grow coffee and sugar cane, and used the money in exchange for food for local residents. However, due to over-exploitation of land and lack of planning, the futures value of coffee and sugar plummeted in a short time, and the economies of South American countries collapsed immediately. Coupled with soil erosion and pesticide abuse, Africa's land has become barren or even desertification, leading to famine. The emergence of sustainable development is to correct past mistakes and prevent other countries from repeating the same mistakes. Sustainable development emphasizes that development within the economic system must be interlocking and self-sufficient. At present, the world-recognized definition of the concept of sustainable development comes from 1987 "Our Common Future", a report of the World Commission on Environment and Development: "A development model that can meet our present needs without compromising the future generations' ability to meet their needs. Three elements of sustainable development Sustainable development is not simply equivalent to ecological or environmental protection. Generally speaking, it includes three aspects. * environmental element (Ecological ect) refers to minimize the damage to the environment (Environmental Impact). Although this principle has been recognized by all parties, due to the limitations of human scientific knowledge at present, there will be diametrically opposite understandings on many specific issues, such as nuclear power plants. Supporters believe that it can reduce greenhouse gas emissions and is environmentally friendly. Opponents believe that nuclear waste has long-term radioactive pollution, and nuclear power plants have potential safety hazards and are not environmentally friendly. * Social ect means still meeting human needs. Sustainable development does not mean that human beings return to primitive society, although human beings did little damage to the environment at that time. * Economic ect means that it must be economically profitable. This has two meanings. First of all, only economically profitable development projects can be promoted and their sustainability can be maintained. Second, economically losing projects must be subsidized by other profitable projects to make a living, which may cause environmental protection here at the expense of more serious environmental damage elsewhere. Due to the rapid increase of population and wealth, the natural resources of the earth can not meet the needs of human beings, and the contradiction between man and nature is more prominent. Therefore, it is necessary to prohibit the wanton abuse of natural resources regardless of future generations and build a sustainable society. A sustainable society should meet the following conditions: 1. It is necessary to realize not only intergenerational justice, but also internal justice, that is, the development of some contemporary people cannot harm the interests of others. 2. Economic and social development should conform to the law of dynamic balance of the earth's ecosystem and the principle of sustainable utilization of resources. 3. Change the unreasonable resource consumption pattern. 4. Solve the global poverty problem and improve the quality of life of the poor. 5. The deterioration of the earth's environment has been curbed and fundamentally improved. 6. Solve international disputes in advance on the basis of equality, justice and respect for countries, and replace confrontation with dialogue. 7. Rely on science and technology to further solve the main problems in sustainable development.
