Needless to say, this is of course a great benefit. The development of science is mainly driven by the advancement of science and technology. Therefore, the reasons are as follows:

First, science and technology will promote human development. of development. After all, no matter how advanced the machine is, it is invented and created by humans and depends on people to use it. And those who have gained convenience due to the creation of tools will be eliminated by society if they give up their human labor instinct because they rely on machines. However, this does not mean that the development of science and technology will hinder human progress, because everything has two sides. The same is true for technology. It is a double-edged sword. How to use it depends entirely on ourselves. We cannot deny the progress that technology has brought to human beings because of personal factors, because humans are always the most advanced intelligent creatures. Computers play an important role in some aspects. In terms of performance, it is very excellent, but computers will never be smarter than the human brain, because no matter what, machines need to be invented by people, and they will not generate themselves.

Second, technology is the primary productive force. Without the advancement of science and technology, how could there be today's high level of development of human material civilization and spiritual civilization? The key to scientific and technological progress lies in innovation. Innovation is the soul of a nation’s progress and the inexhaustible driving force for a country’s development. Without scientific and technological progress, there would be no prosperity and stability for our motherland. Scientific and technological progress will greatly promote human development.

Third, the development of science and technology will promote the all-round development of people. Because the development of science and technology has created development conditions for the all-round development of people, people can continuously improve themselves and develop themselves in all aspects under the premise of the development of science and technology. Therefore, the development of science and technology will promote the all-round development of people.

To see whether an issue is right or wrong, good or bad, all depends on the mainstream of its existence. For example, drugs can cure diseases, and sometimes It can save lives, but it also has side effects. Can you say it's bad? Even the best things will inevitably have side effects. Therefore, the development of science and technology can ultimately promote the overall progress of mankind.

Fourth, whether the development of science and technology promotes the overall development of human beings should be measured in this way. First, look at Whether people's average life span is extended depends on whether people's thinking methods have progressed, whether people's comprehensive physical ability and intelligence have developed, and whether humans have developed a better grasp of the natural world.

In addition, from From another perspective, a university teacher once asked his students this question: "What will life be like if one day we leave 'science' and everything it brings?" The students looked at each other. In the end, everyone’s answer was: incredible.

Yes, science is so important to people’s lives. Not only the televisions, computers, cars, mobile phones, etc. that accompany us day and night are closely related to science, but also the rice we eat, the water we drink, the clothes we wear, the electricity we use, as well as the equipment and medicines used for medical treatment. , all these things, what has nothing to do with science? If we want to live, we cannot leave science for a moment.

People cannot survive without science, and development cannot do without science. Without the word "science", we cannot move forward well and quickly.

Our understanding of the laws of development has been in the process of deepening. Since the reform and opening up, we have worked hard to promote rapid economic development, resulting in significant changes in the urban and rural landscape and continuous improvement in people's living standards. However, on the road to rapid development, various problems such as constraints on population, resources, and environment, imbalances in urban-rural, regional, economic and social development, and contradictions in the distribution of social resources and wealth have posed before us. Therefore, at the critical stage, the Party Central Committee inherited and developed the important ideas on development of the three generations of central leadership collectives of the Party, put forward the scientific concept of development, and further answered the questions of “development for whom”, “development by whom” and “how to develop”. From "development" to "scientific development", from "fast and easy development" to "good and fast development" is a qualitative leap in understanding the laws of development. It will not only determine our tomorrow, but also have a profound impact on the future of the world. Influence.

The scientific outlook on development has brought us exciting changes. We have seen that with the implementation of the Scientific Outlook on Development, our province's economic and social development continues to take new steps, people's living standards continue to improve, and the ability of sustainable development continues to increase. Pollution has been reduced, the water in some lakes has become clearer, the sky is bluer, the Yunling land is more green, and the environment is more beautiful. The benefits brought by scientific development can be seen and touched by the people of all ethnic groups across the three continents. The in-depth implementation of the Scientific Outlook on Development has enabled the word "science" to show new power and shine brighter.

Comrade Hu Jintao pointed out in the report of the 17th National Congress: The Scientific Outlook on Development is an important guiding principle for my country’s economic and social development and a major strategic thought that must be upheld and implemented in the development of socialism with Chinese characteristics. These words express the unified aspiration of the people of all ethnic groups in China. The light of science is brilliant and the power of scientific development is endless. As long as we unswervingly follow the path of scientific development and let the light of science illuminate our hearts, the future will surely be happier and better.

The following are debate materials about scientific development: pros and cons, I hope it will be helpful to your debate

Let’s talk about the pros and cons of science and technology

Pro: United States Columbia University

Opposer: Russia’s Moscow Institute of International Relations

But it said that the National University of Singapore regretted losing in the afternoon. In the evening, the University of Malaya will compete again with Shih Hsin University. Under the light, I saw two teams of people lined up on both sides.

This contest is about whether "the development of science and technology will promote or inhibit the all-round development of human beings."

University of Malaya is on the right track. After all, it was the last champion, so it can be seen that they are somewhat confident. A female general stood up and called out: Look at history. From printing to papermaking, from word processors to the sharing of network information, people's intelligence can be deepened. This is the driving force of humanity; from the perspective of human spiritual value Generally speaking, technology has freed people from the shadow of poverty. Network technology information has brought about the fourth wave of thinking about democracy and human rights. Physiologically, from antibiotics to organ transplantation, from water conservancy and irrigation to the improvement of biological species, they have all brought relief to mankind. Crisis after crisis, when the development of science and technology brings about the deepening, broadening and optimization of people's physical, psychological and spiritual values, can the other debater still say that the development of science and technology has inhibited the all-round development of people? This general has a strong nature and is called Gan Caizhen.

Huang Jingwen, a female general from Shih Hsin University who came out to fight, had a gentle temperament and spoke at a gentle pace: We admit that technology promotes human development, but while technology satisfies human desires, it often promotes and inhibits one side at the same time. the other side. Therefore, the role of science and technology in promoting human development is not comprehensive. Just like a student got full marks in many courses, but got 0 points in one subject, even if he is better than before, we cannot say that he is comprehensively better.

The offense and defense of both sides are suitable, and there are some rounds in the battle. I can see that the positive side is erratic, hiding mysteries; the negative side is calm and restrained, condescending. After a short while, the opponent, Zhuang Zhikai, and the opponent, Chen Jintian, were locked in a battle, and they were inseparable.

Zhuang Zhikai asked: "In Malaysian education, primary school students are required to learn mental arithmetic and are not allowed to use computers to answer questions. Why is this?"

Chen Jintian said: "Because the orientation Comprehensive development is a dynamic process, so first learn mental arithmetic, then learn computers, and slowly learn from more and more fields, moving from partial to comprehensive."

Zhuang Zhikai said: "Friends on the other side, We know that we should not let them use computers instead of doing mental arithmetic, because we are afraid that their mental arithmetic ability will decline if they use computers."

Chen Jintian said: "We know that mental arithmetic ability is very important, and computers are even more important, so we do. We need to learn both, learn the first step first and then the other. When we expand this part more and more, we will move towards comprehensive development." Chen Jintian did not give up and took the opportunity to reply: I asked. You, do we have to follow the example of the Taliban government today in banning people from accessing the Internet, so that people can develop in an all-round way as the other party said?

Zhuang Zhikai replied with a smile: We are not talking about whether to use technology or not. If so, we would not need to talk about it today. We are talking about the problems that technology brings to our overall development. Turning to the question: Are the environmental pollution problems, unemployment problems, and the decline of some human functions caused by the development of science and technology considered problems?

Tim Chan said: Today I will admit that technology has some minor drawbacks.

Zhuang Zhikai asked: What does a small fraud mean?

Chen Jintian said: That is to say, it can be solved through science and technology, and it will not affect the overall development of people.

Zhuang Zhikai asked: If the development of science and technology does not bring about these problems, why does it need to solve the problems?

After a long exchange of words, everyone could only hear laughter and applause.

But in this battle, both sides were evenly matched on the scene, each with their own moves. Law enforcement officials from all walks of life pondered for a while, and finally decided that the opponent, Shixin University, was the winner. After all, they had won the previous championship, and they were still a little excited. However, competing with Sun Yat-sen University for the title will inevitably be a life-and-death battle.

Mankind has entered the 21st century, and the world has undergone many amazing changes. While people are delighted with the rapid development of science and technology, they have also experienced greater uneasiness and even disaster. In addition to the panic caused by the development of high technology, especially biotechnology, war and disease seem to bring mankind directly to the gate of hell.

The epidemic of SARS in 2003, including all speculation about SARS, is directly related to a global issue of growing concern: biosecurity. Biosafety is a scientific and technological system for the detection, evaluation, monitoring, prevention and management of biological hazards. It is the study of the impact of various biological factors on human health, the application of existing theoretical knowledge, technology, engineering design and equipment, etc., to prevent It is an emerging frontier discipline in which the personnel, laboratories and environment involved in the work are endangered by potentially infectious substances and biotoxic substances. Biosecurity issues are at least manifested in the following aspects:

The huge harm of infectious diseases

Infectious diseases include human, animal, and plant infectious diseases, especially human infectious diseases are the most important Regarding biosecurity issues, infectious diseases are still the number one cause of death in the world. In our country, infectious diseases still seriously threaten people's health 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 break out in some parts of the country and some countries and regions in the world every year

Potential threats of biological weapons and bioterrorism

The entire international community in the 20th century Society has made unremitting efforts to ban biological weapons and has made some progress.

However, in the 21st century, the potential threat of biological weapons has greatly increased. Some countries and regions may continue to research and develop biological weapons. In addition, the rapid development of biotechnology has greatly increased the potential threat of biological weapons, such as the "Anthrax Incident in the United States". "Bioterrorism as a symbol has posed a real threat to international security. Yuen Kwok-yung, chairman of the Department of Microbiology at the University of Hong Kong, was the first scholar to isolate a coronavirus and discover that coronavirus variants are the causative agent of SARS. SARS virus is an RNA virus. The characteristic of this virus is that it can easily recombine with other viral genes and become a new virus. Moreover, many experimental results also show that the new viruses produced through this change will be more virulent than the parent viruses. Coronavirus can be found in many animals, and this virus can easily mutate and is extremely dangerous. Therefore, Yuan Guoyong believes that the SARS virus has great potential and can become a pathogen for the production of biochemical weapons in addition to smallpox.

The negative effects of biotechnology

The negative effects of biotechnology are mainly as follows: First, unexpected safety problems may arise when people develop and utilize biotechnology. Just as there is widespread concern about the harm to biodiversity caused by the release of various genetically modified living organisms into the environment. In addition, genetically engineered drugs, vaccines, genetically modified foods, gene therapy, etc. may have similar problems. Misuse of biotechnology and unethical applications of biotechnology may also pose significant safety risks. The study of somatic human cloning is a prominent example.

Threats to biological resources and biodiversity

From a biosecurity perspective, the invasion of alien species and the loss of biological resources may cause huge damage to national interests. The environmental release of genetically modified organisms poses a great threat to biodiversity.

Safety hazards in microbiology laboratories

Compared with other physical and chemical laboratories or other types of laboratories, the microbiology and biomedical laboratory is a special laboratory in which Everyone who works and the surrounding environment in contact with them is at high risk of contracting infectious diseases or affecting their health. Omissions and accidents in microbiology laboratory management can not only lead to infection of laboratory workers, but also cause environmental pollution and large-scale population infection. Accidental infections in laboratories at home and abroad are not uncommon. In severe cases, tens of thousands of experimental animals have to be slaughtered, and even laboratory workers die.

With the rapid development of biotechnology, biosafety issues have become a major issue affecting the politics, economy, security and peace of the entire country and the entire world. In recent years, especially after the "anthrax infection incident" in the United States, biosafety issues have attracted much attention at home and abroad. Biosafety terms are often seen in government or non-governmental organization documents and in various media. The global epidemic of SARS will undoubtedly make countries around the world pay more attention to biosecurity issues and regard them as an integral part of national security.

With the development of the economy, the acceleration of people's pace of life and the improvement of living standards, the amount of plastic used

is increasing day by day. In 1996, my country's plastic packaging consumption reached 2.43 million tons, with an average annual growth rate of more than

20%. In particular, plastic waste in garbage in cities, along major transportation lines, and tourist attractions has increased rapidly.

According to surveys, Beijing's annual domestic waste production has reached 3 million tons, of which waste plastics account for about 3%, with an annual growth rate of 48%. The plastic content of garbage in coastal cities is higher, reaching 8-10%. The proportion of these waste plastics in the garbage has reached more than one third if calculated by volume, and it has greatly increased the difficulty and cost of garbage disposal.

Since waste plastic is difficult to degrade for hundreds of years, if it is discarded in the natural environment, it will provide a breeding ground for mosquitoes, flies and

bacteria; if it is buried underground, It easily pollutes groundwater, hinders the growth of plant roots, damages soil quality, and affects crop harvests; if burned with fire, a variety of toxic gases will be produced. "White pollution" has become a major public hazard that harms our country's social environment and has seriously hindered the sustainable development of our country's economy and environment.

At present, the annual consumption of disposable tableware in our country is about 10 billion pieces, mainly foam plastic products. It is necessary to prohibit the production, sale and use of these large-volume and wide-ranging disposable tableware.

Foam plastic tableware requires the development and production of alternatives, and green disposable tableware came into being. Relevant experts believe that the development and production of green disposable tableware is becoming an emerging environmental protection industry in my country.

In mid-December, the Ministry of Science and Technology, together with the State Economic and Trade Commission, the State Environmental Protection Administration, and the Ministry of Railways, jointly held a green disposable tableware technology development exchange meeting. At the meeting, reporters interviewed Head of the Rural Technology Development Center

Wang Zhixue and managers of several production enterprises.

Wang Zhixue said: The green disposable tableware currently developed and produced in my country can be divided into paper pulp, rice husk, straw and starch according to the type of raw materials. There are currently hundreds of companies in my country producing paper disposable tableware, with an annual production capacity of approximately 3 billion pieces.

The raw material production process of paper tableware is seriously polluted, the cost is high, and its strength and waterproof and moisture resistance

are poor. Therefore, its promotion and application have great limitations. Sex, people naturally look elsewhere and seek benefits from science and technology. For example, rice husk is used as raw material to produce rice husk tableware. There are now more than a dozen companies of this type in my country, with an annual production capacity of about 150 million pieces; straw tableware is mainly made of crop straw.

Raw materials: my country currently has more than a dozen manufacturers with an annual production capacity of 75 million pieces; starch tableware uses potatoes

Starch is the main raw material. It has good degradability and can be recycled Later it can be used as feed. All in all, the country attaches great importance to the research and development of green disposable tableware, and provides strong support through scientific and technological development plans such as scientific and technological research, Spark Plan, and Torch Plan. The company's green disposable tableware production technology is relatively mature and has the foundation for industrialization.

Wuhan Far East Green World Group Co., Ltd. is a company that uses starch as raw material to carry out technological research and development of green disposable tableware,

and has begun to take shape in economic benefits. The experience of Su Xiaohai, the president of the company, is quite legendary:

He originally studied arts and crafts at Hubei Institute of Light Industry. In 1984, he entered Wuhan University to study for a master's degree in philosophy

and later While studying and working in Germany, he was deeply touched by the environmental protection in Europe, and he came up with the idea of ??returning to China to engage in the environmental protection industry. Su Xiaohai told reporters: I studied arts and crafts and am an aesthete. My involvement in environmental protection causes such as green tableware today originated from my initial understanding of beauty; and the continuation of aesthetics

Extension, in the final analysis, is also a philosophy.

Between 1992 and 1996, Far East Green World developed recycled cardboard disposable tableware and reed pulp

Due to low technological content and other reasons, the production scale of molded tableware It has never been able to expand. In 1996, the company sent personnel to inspect the technical situation of biodegradable packaging products in the European market and believed that the development of plant starch production

fully degradable disposable tableware may be the key to eliminating "white pollution" a way. In 1997, composed of a group of food, chemical, and mechanical experts, the company focused on investing in the development of fully degradable disposable catering supplies. This project was included in the 1997 National Torch Plan projects.

They absorbed foreign advanced technology and combined it with domestic paper tableware production technology to carry out a series of innovations: using

domestic sweet potatoes, corn and other starches that are rich in resources as the main raw materials, instead of The single higher-priced potato starch from abroad is replaced; 20% of natural fiber is added to the sweet potato starch raw material, which increases the obvious strength of the tableware. The processing technology of food puffing makes the product light weight and soft; the surface spraying and shaping equipment to increase the strength make the food and beverage products produced have waterproof, oil-proof and heat-resistant functions. Su Xiao

Hai made a vivid metaphor: It is like the steel and cement in building materials. Sweet potato starch is the cement, and

the various hay and hay that are chopped and mixed are The rhizomes of the plants are the steel bars, so that the strength of the tableware can be significantly enhanced

.

The starch-based tableware products produced by Far East Green World are tested by the German SGS agency with reference to international food packaging standards.

The tableware products are filled with hot water and hot oil at 100 degrees Celsius. It does not deform at all for more than two hours and has excellent thermal insulation performance. Since starch and additives are natural plant raw materials, the product has excellent degradation performance. Tests by the National Environmental Testing Center show that it can degrade more than 90% in about 10 days and can be completely degraded within a month.

According to reports, since the project uses plant starch and plant fiber, the cost is low. Each rice box with rice bowl

costs about 0.12 yuan, and rice box without rice bowl and bowl. , the listing cost is about 0.07 yuan, and it has broad market prospects.

Currently, Far East Green World plans to invest 160 million yuan to build a large-scale factory with an annual output of 5 billion pairs of disposable chopsticks and 3.5 billion pieces of various

bowls, plates, boxes and other products. The fully degradable green disposable tableware production base, after the project reaches full production, can add an annual output value of 625 million yuan and an additional profit and tax of about 130 million yuan.

The civil construction project of the base started in March this year.

A standard factory building of 20,000 square meters has been built. If follow-up funds can be guaranteed, it is expected to reach production by the end of 1999.

Su Xiaohai Said: Our scientific and technological advantages are obvious, and the social benefits we can create in the future are also obvious: the functional indicators of disposable sanitary chopsticks made of starch can completely replace disposable wooden chopsticks. This project can save nearly 500,000 cubic meters of wood resources for the country every year. If the group can reach production, it is expected to use more than 200,000 tons of sweet potatoes every year to process them into starch. With more than 100,000 tons of raw materials, it can also lift more than 100,000 people in poor areas out of poverty and promote the development of agricultural industrialization in old areas.

Shantou Luheng Industrial Co., Ltd. has been developing green disposable tableware made from rice husks in the past few years. At present,

it has initially acquired the ability to produce on an industrial scale. The company produces Disposable packaging containers made of rice husks, especially food packaging containers used in supermarkets, have begun trial sales in Japan, Taiwan, the United States and other countries.

The green disposable tableware produced by Luheng Company is made by crushing and sifting rice husk, then mixing it with several edible organic polymer adhesives and water, and then Through stamping, drying, spraying and other processes, plates, bowls and other utensils of different shapes are produced.

Ji Xiaopeng, general manager of Luheng Business Co., Ltd., said: Disposable tableware is made of rice husk, which is not only rich in resources in our country and inexhaustible, but also It can be quickly degraded in the soil after use, which can be said to kill two birds with one stone.

Lvheng Company currently has a production line in operation, with an investment of approximately 9.8 million yuan and a production capacity of 400,000 pieces of tableware/day, currently reaching 200,000 pieces of tableware/day. sky. The annual output value is about 36 million yuan, the investment recovery period is expected to be about one and a half years

and the investment profit is about 30%. The production technology and product quality have passed the certification organized by the Guangdong Provincial Science and Technology Commission

Technical appraisal and inspection by the food hygiene department. According to reports, in order to better bring products to the market and operate on a large scale, the company plans to establish a group company in the near future and invest funds in technological transformation in order to improve production

The line is more automated.

According to the green tableware technology development exchange meeting hosted by the Ministry of Science and Technology, on July 18, 1998, Vice Premier Wen Jiabao attended a meeting on the prevention and control of water pollution in the Taihu Lake Basin. It specifically proposed to solve the "white pollution" along the Yangtze River, Taihu Lake and

railway within one year, requiring relevant departments of the State Council to focus on three tasks. First, strengthen management,

prohibit Littering; second, stop using disposable foam plastic tableware; third, develop and mass-produce alternatives as soon as possible. On November 14, Vice Premier Li Lanqing also raised the issue of the promotion and application of foam plastic tableware alternatives at the 12th National Patriotic Health Campaign Committee working meeting. It seems that green disposable tableware has attracted great attention from central leaders and relevant departments such as science and technology and environmental protection. As an emerging environmental protection industry, it can be said that it is born. It's just the right time. Now, we need our scientific and technological personnel who can climb the peak of science to continue to engage in research and development. We need our entrepreneurs who know business and are good at management to increase technological innovation and market development. , we also need our far-sighted financiers and venture capitalists to provide sufficient capital investment for the industrialization of green disposable tableware.

Most of the enterprises in my country engaged in the development and industrialization of green disposable tableware currently have small production scales and weak ability to withstand the storm

And many of them are private enterprises and need Government departments should provide sufficient industrial policy support and guidance and get off to a good start, allowing this emerging green environmental protection industry to develop healthily and sustainably.
