1, narrow sense green: the narrow sense green mentioned above is a basic content of material green. It includes a good natural environment and ecological environment. The Olympic Charter requires the natural environment and ecological environment of the host city of the Olympic Games, so the narrow sense of green is what the host city of the Olympic Games must do, which also makes it one of the basic conditions for hosting the Olympic Games. Environmental problems have always been a big problem in Beijing, and many treatments are only temporary solutions, such as the transformation of Xiaoqing River. The improvement of the environment is not only the government's business, but the business of all Beijing citizens. Governance without protection will not have long-term effects. 2. Venues and transportation: The construction of venues and transportation should be more humane. Scientific and economical, at the same time, we should give full consideration to the reuse before and after the Olympic Games to avoid causing economic development to the organizers. People's lives have caused unnecessary negative effects; All previous Olympic Games have attached great importance to the construction of venues and transportation, and there are always some original designs. such as

The Australian National Track and Field for the 2000 Sydney Olympic Games was once the beef cattle storage area of the slaughterhouse. The canopy is specially designed for Australia's climate environment, so that athletes and spectators who participate in daytime competitions have enough light. There is also its unique environmental protection feature: the design of the sports ground considers natural ventilation and does not use any mechanical ventilation to erect it. Specially designed reflectors get maximum sunlight. Thereby reducing the need for artificial lighting. All rainwater is collected from the roof to four large water tanks for watering the venues, and the recovered water is used for flushing toilets. There are various water-saving devices everywhere on the playground. In the design of sports ground, the use of PVC is minimized, and all building materials have passed the service life cycle test. Natural gas generators that are beneficial to the environment are used as backup equipment for the main power supply. In addition, there are some special facilities designed for the disabled and other special groups. All these reflect the green of venue construction. 3. Funds: The funds for hosting the Olympic Games should also be green, and there should be no unwarranted increase in investment in the Olympic Games, which may have a very negative impact on the Olympic Games. The Montreal Olympic Games in 1976 and the Moscow Olympic Games in 1980 could not be recovered because of excessive investment, which had a great negative impact on the urban economy and residents. 4. Management: Green Olympics requires that its management is also green. Manage the organization. Strictly control the composition of personnel and run the Olympic Games well with less resources. The Olympic Games will bring more employment opportunities to the host city, involving many people. How to use these resources and how to coordinate people and money. Everything is something that the organizers of the Olympic Games need to consider. 5. Events: The number of Olympic events has increased year by year, reaching 300. Many people are skeptical about the excessive increase of Olympic events and the excessive expansion of the Olympic scale, and think that this unlimited expansion will enhance the political nature of the Olympic Games. The weakening of appreciation runs counter to Mr. Coubertin's aim of establishing a modern Olympic movement, and such a trend may ruin the Olympic movement. Moreover, due to the Olympic Games' control over the number of individual gold medals, many new events entering the Olympic Games have to change their original appearance and compete in different forms, which is not necessarily conducive to the development of the events, and may lead to the disappearance of the diversity of the events. 6. Sports nutritional supplements: sports need nutritional supplements, and sports training needs effective recovery and improvement methods, but it cannot exceed the boundaries of prohibited drugs and prohibited methods stipulated by the IOC Drug Administration Committee. This is the green color of sports nutritional supplements. Of course, material green is not limited to these aspects. Only by fully mobilizing the functions of various materials and making the Olympic Games more in line with the requirements of the natural environment and social environment can it be called real material green.
