Five examples of "technological development has done much harm".

This is because of the amazing changes that have taken place in the world as mankind has entered the 21st century. While people are happy about the rapid development of science and technology, they have experienced better uneasiness and even disaster. Apart from the panic over the development of high technology, especially biotechnology, wars and diseases seem to have brought mankind directly to the gates of hell. The SARS epidemic of 2003, including all the speculation about SARS, is directly linked to a growing global concern: biosafety. Biosafety is a scientific and technological system for the detection, evaluation, monitoring, prevention and management of biological hazards. It is an emerging fringe discipline that studies the impact of various biological factors on human health, and applies existing theoretical knowledge, technology, engineering design and equipment, etc., to prevent personnel engaged in related work, laboratories and the environment from being jeopardized by potentially infectious and biotoxic substances. Biosafety issues are manifested in at least the following aspects: the great danger of infectious diseases infectious diseases, including human, animal and plant infectious diseases, especially human infectious diseases is the most important biosafety issues, infectious diseases are still the first cause of death in the world, in our country, infectious diseases are still a serious threat to the health of the people and national security. the epidemic of SARS is a strong proof. In addition, infectious diseases such as hepatitis, tuberculosis and influenza are still prevalent or outbreaks in some parts of the country and some countries and regions in the world every year Potential Threats of Biological Weapons and Bioterrorism In the 20th century, the whole international community has been making unremitting efforts to prohibit biological weapons and some progress has been made. However, as we enter the 21st century, the potential threat of biological weapons has greatly increased, and some countries and regions may still continue to research and develop biological weapons. In addition, the rapid development of biotechnology has greatly increased the potential threat of biological weapons, and bioterrorism, symbolized by the anthrax incident in the U.S., has already posed a real threat to international security. The anthrax incident in the United States is a real threat to international security. Yuen Kwok-yung, head of the Department of Microbiology at the University of Hong Kong, was the first scholar to isolate a coronavirus and to discover that a variant of the coronavirus was the pathogen of SARS, an RNA virus that can easily recombine with other viral genes to become a new virus. Many experiments have shown that new viruses produced in this way are more virulent than their parents. Coronaviruses can be found in many animals, and they can easily mutate, making them extremely dangerous. Therefore, Yuan Guoyong believes that the SARS virus has great potential to become a pathogen for making biochemical weapons other than smallpox. Negative effects of biotechnology The negative effects of biotechnology are mainly manifested in the following ways: Firstly, when people develop and utilize biotechnology, there is a possibility of unexpected safety problems. Just as the current widespread concern about the hazards to biodiversity posed by the release of various types of genetically modified living organisms into the environment. In addition, genetically engineered drugs and vaccines, genetically modified foods, gene therapy, and so on, may have similar problems. Misuse of biotechnology and unethical application of biotechnology may also pose significant safety risks. The research on somatic cell cloning of human beings is a prominent example. Threats to Biological Resources and Biodiversity From the perspective of biosafety, the invasion of alien species and the loss of biological resources may cause great damage to national interests. The environmental release of genetically modified organisms poses a great threat to biodiversity. Safety Hazards in Microbiology Laboratories More than other physical and chemical laboratories or other types of laboratories, microbiology and biomedical laboratories are special laboratories in which everyone working in them, and the surroundings with which they come into contact, are at high risk of contracting infectious diseases or affecting their health. Negligence and accidents in the management of microbiological laboratories can lead not only to infections among laboratory workers, but also to environmental contamination and large-scale population infections. Accidents of accidental infection in laboratories at home and abroad are not uncommon, and in serious cases, thousands of laboratory animals have to be slaughtered, even leading to the death of laboratory staff. At present, with the rapid development of biotechnology, the issue of biosafety has become a major proposition affecting the politics, economy, security and peace of the whole country and the whole world. In recent years, especially after the anthrax infection in the U.S., the biosafety issue has attracted much attention both at home and abroad, and biosafety terminology is often found in the documents of governmental or nongovernmental organizations, and in all kinds of media. the global epidemic of SARS will undoubtedly make countries all over the world pay more attention to biosafety and take it as an integral part of national security. The global epidemic of SARS will undoubtedly make countries all over the world pay more attention to biosafety and make it a component of national security. With the development of the economy, the accelerated pace of life of the people and the improvement of living standards, the amount of plastic is increasing day by day. 1996, the amount of plastic packaging in China reached 2.43 million tons, with an average annual growth rate of more than 20%, especially the rapid increase of plastic waste in the garbage in the cities, along the main transportation routes, and in tourist attractions. According to the survey, the annual output of domestic garbage in Beijing has reached 3 million tons, of which waste plastics accounted for about 3%, with an annual growth rate of 48%. The plastic content in the garbage of cities in coastal areas is even higher, amounting to 8-10%. The proportion of waste plastics in the garbage is more than one-third if calculated by volume, and it greatly increases the difficulty and cost of garbage disposal. Since waste plastics are difficult to degrade for hundreds of years, if they are discarded in the natural environment, they will provide a breeding ground for mosquitoes, flies and bacteria; if they are buried in the ground, they will easily pollute the groundwater, impede the growth of plant roots, damage the quality of the soil, and affect the crop yield; if they are incinerated in a fire, a variety of toxic gases will be produced. "White pollution" has become a major public hazard that jeopardizes the environment of our society and seriously impedes the sustainable development of our economy and environment. At present, China's annual consumption of disposable tableware is about 10 billion, mainly for foamed plastic products, to prohibit the production and sale of these large quantities of disposable foamed plastic tableware, we need to develop and produce its alternatives, green disposable tableware thus came into being. Experts believe that the development and production of green disposable tableware is becoming a new environmental industry in China. In mid-December, the Ministry of Science and Technology in conjunction with the State Economic and Trade Commission, the State Environmental Protection Administration, the Ministry of Railways jointly convened a green disposable tableware technology development exchanges, at which the reporter interviewed Wang Zhixue, head of the China Rural Technology Development Center, as well as a few producers of business managers. Wang Zhixue said: At present, China's development and production of green disposable tableware according to the types of raw materials can be divided into pulp, rice husk, straw and starch. China's existing hundreds of enterprises to produce paper disposable tableware, annual production capacity of about 3 billion. Paper tableware raw materials in the production process of serious pollution, high cost, and its own strength and waterproof moisture resistance is poor, therefore, its popularization and application has greater limitations, people will naturally look elsewhere, to the benefits of science and technology. Such as rice husk as raw material production of rice husk tableware, China now has more than a dozen of this type of enterprise, the annual production capacity of about 1.5 billion; straw tableware to crop straw as the main raw material, China now also has more than a dozen manufacturers, the annual production capacity of 75 million; starch tableware to potato starch as the main raw material, it is a good degradation, recycling can be done after the feed. All in all, the state attaches great importance to the research and development of green disposable tableware, through scientific and technological research, the Spark Plan, the Torch Plan and other scientific and technological development plans to give strong support, many enterprises of the green disposable tableware production technology has been relatively mature, with the basis of industrialization. Wuhan Far East Green World Group Company is a company that takes starch as raw material and carries out scientific and technological research and development of green disposable tableware, and its economic benefits have begun to take shape. The company's president Su Xiaohai's experience is quite legendary: he originally studied arts and crafts in Hubei Light Industry Institute, entered Wuhan University in 1984 to read a master's degree in philosophy, and then studied and worked in Germany, European environmental protection touched him a lot, and gave birth to the idea of returning to China to engage in environmental protection industry. Su Xiaohai told the reporter: I have studied arts and crafts, and I am an aestheticist, and my commitment to environmental protection such as green tableware today is based on my initial understanding of beauty; and the extension of aesthetics, in the final analysis, is also a philosophy. Between 1992 and 1996, the production scale of the recycled cardboard disposable tableware and reed pulp molded food and drink utensils developed by the Far Eastern Green World Company had not been expanded due to the relatively low technological content, etc. In 1996, the company sent staff to investigate the technological situation of biodegradable packaging products in the European market, and believed that the development of plant starch production of fully degradable disposable tableware products might be a way to eliminate "white pollution" and to make it easier for the company to produce biodegradable products. "In 1997, composed of a group of food, chemical and mechanical experts, the company focused on investing in the development of fully degradable disposable food and beverage products, which was included in the 1997 National Torch Program. They absorb foreign advanced technology, combined with the domestic production process of paper tableware for a series of innovations: the use of domestic resources of sweet potato, corn and other starch as the main raw material, instead of a single foreign higher-priced potato starch; in the sweet potato starch raw materials increased by 20% of natural fibers, so that catering products increase the strength of the obvious, and then use the food puffing processing technology to make the product has a lightweight and softness; increase the strength of surface spraying; increase the strength of the surface, and the product has a lightweight and softness; increase the strength of the surface spraying. The use of food puffing processing technology to make products with light weight and softness; increase the strength of surface spraying treatment and shaping equipment, so that the production of food and beverage supplies with waterproof, oil-proof, heat-resistant function. Su Xiaohai made a vivid analogy: it is like the reinforced concrete in the building materials, sweet potato starch is the concrete, and various hay and plant roots chopped and stirred into it are the reinforced concrete, so as to make the tableware's strength significantly enhanced. The starch-based tableware products produced by Far East Green World are tested by German SGS organization with reference to the international food packaging standard, and they are not deformed when they are filled with hot water and hot oil at 100 degrees Celsius for more than two hours, with excellent temperature preservation performance. Due to the starch and additives are natural plant raw materials, the product degradation performance is excellent, the National Environmental Testing Center test shows that about 10 days can be degraded more than 90%, within a month can be completely degraded. According to reports, because the project uses plant starch and plant fiber, the cost is low, each lunch box with a lid costs about 0.12 yuan, no lid lunch boxes and bowls, plates cost about 0.07 yuan, has a broad market prospects. At present, the Far East Green World Company intends to invest 160 million yuan to build a large-scale production base for fully-degradable green disposable tableware with an annual output of 5 billion pairs of disposable chopsticks, 3.5 billion various types of bowls, trays, boxes and other products, which will have a new output value of 625 million yuan per annum and a new profit and tax of 130 million yuan when the project reaches production. The civil engineering of the base has been started in March this year, has built a standard plant of 20,000 square meters, if the follow-up funds can be guaranteed, it is expected that the end of 1999 can reach production. Su Xiaohai said: our scientific and technological advantages are obvious, the future can create the social benefits are also obvious: with the starch made of disposable health chopsticks, its functional indicators can completely replace the disposable wooden chopsticks, this alone, that is, each year, for the country to save wood resources of nearly 500,000 cubic meters; group if you can reach the production, it is expected that each year we will use more than 200,000 tons of sweet potatoes, processed into starch raw materials more than 100,000 tons, can make more than 100,000 people in poor areas, can make more than 100,000 people in poor areas. It can make more than 100,000 people in poor areas get rid of poverty and promote the development of agricultural industrialization in old areas. Ltd. started to develop green disposable tableware made of rice husk in the previous years, and now it has the ability of industrialized scale production, and the disposable packaging containers made of rice husk produced by the company, especially the food packaging containers used in supermarkets, etc., have started to be exported to Japan, Taiwan, the U.S.A., etc. on a trial basis. The green disposable tableware produced by Green Heng Company is made by crushing and sieving rice husk, then mixing it with several kinds of edible organic polymer adhesives and water, and then producing different shapes of plates and bowls through the processes of press molding, drying, and spraying, etc. The green disposable tableware produced by Green Heng Company is made by crushing and sieving rice husk, then mixing it with several kinds of edible organic polymer adhesives and water. Ltd. general manager Ji Xiaopeng said: disposable tableware to rice husk as raw material, not only in China's abundant resources, inexhaustible, and it can be used after the rapid degradation of the soil, can be said to be two birds with one stone. Green Heng Company has a production line in operation, its investment is about 9.8 million yuan, production capacity of 400,000 tableware / day, currently up to 200,000 tableware / day. The annual output value is about 36 million yuan, the expected payback period is about one and a half years, the investment profit is about 30% or so, the production technology and product quality has passed the Guangdong Provincial Science and Technology Commission organization of technical appraisal and food hygiene department's inspection. According to the introduction, the company in order to better market the product, the scale of operation, intends to set up a group of companies in the near future, and to invest in technological transformation, with a view to making the production line of higher degree of automation. According to the Ministry of Science and Technology held under the auspices of the green tableware technology development exchanges, July 18, 1998, Wen Jiabao, Vice Premier of the Taihu Lake Basin Water Pollution Prevention and Control Work Conference, specifically proposed to solve the Yangtze River, Taihu Lake, railroads along the "white pollution" within one year, the State Council departments concerned to focus on the work of the three, one is to strengthen management, to prohibit littering. November 14, Li Lanqing, Vice Premier of the 12th National Patriotic Health Committee work conference, also put forward the promotion and application of alternatives to foamed plastic tableware. It seems that the green disposable tableware has attracted great attention from the leading comrades of the central government as well as the relevant departments of science and technology, environmental protection, etc. As a new environmental protection industry, it can be said that it was born at the right time. Now, we need to continue to engage in the research and development of science and technology personnel capable of scaling the scientific peaks and we need to increase the strength of technological innovation and market development of the entrepreneurs who know how to do business and are good at management, as well as our visionary financiers and entrepreneurs who are good at management and are good at market development. We also need our visionary financiers and venture capitalists to see the pearls and give enough capital investment to the industrialization of green disposable tableware. Most of the enterprises engaged in the development and industrialization of green disposable tableware production scale is relatively small, the ability to withstand the storm is weak, and many of them are private enterprises, the need for government departments to give sufficient industrial policy support and guidance, a better start, so that the emerging green environmental protection industry can be healthy and sustainable development.
