I said, this is technology. It is the development of science and technology that promotes the progress of mankind. It is the development of science and technology that enables mankind to have this new and beautiful life. Throughout the ages, which dynasties and generations have not attached great importance to the development of science and technology? Looking back at the past, we can see the four great inventions, which are unique; we can see the astronomical calendar and be amazed by it; we can see the Zhaozhou Arch Bridge, which is exquisitely designed; we can see the "Compendium of Materia Medica", a great oriental classic; we can see the value of pi, which has seven decimal places; and we can see the Silk Road, which has many decimal places. Develop the economy; make blue and white porcelain and become famous overseas. The development of science and technology is the road to a strong country, and the development of science and technology is the first driving force for the progress of the Chinese nation. Without science, how could we have the happy life we ??have today? Without technology, where would we have comfortable material life and spiritual enjoyment? Without the advancement of science and technology, how could we eat Hybrid No. 2? How can we wear pure cotton clothes, how can we live in high-rise buildings?
Ask, does technological development bring more benefits or disadvantages? Needless to say, of course it’s a big win! What's the explanation? No need to explain! The 8,000-year history of Chinese civilization is ironclad evidence. History is changing every moment, and science and technology are developing every moment. Human beings learned to use or cook food from the primitive life of eating hair and drinking blood, from relying on nature to breeding and raising, from being unarmed to metallurgy and stone smelting. Isn't this all progress, isn't this all development? If the disadvantages outweigh the advantages, then why do human beings unanimously choose progress? Only progress can make tomorrow better!
A person who does not progress is sad, a country that does not progress is in decline, and a world that does not progress is dark. Only through continuous progress can human life be sublimated. Human beings are small and fragile. They do not have a huge body, the strength of a cow, or the hard shell of a turtle. But God has given human beings a smart brain and a pair of hard-working hands. Human beings did not sit back and enjoy the fruits of their labor, but chose to continue to make progress, so that they can stand at the top of the food chain today.
Let us compare today’s life with a hundred thousand years ago, we are supreme; compare today with thousands of years ago, we are condescending; compare today with hundreds of years ago , we are happy and comfortable; comparing today with tomorrow, the future is beautiful and bright. Over the past few thousand years, carriages have transformed into cars, trains, and airplanes; kerosene lamps have transformed into incandescent lamps, neon lamps, and energy-saving lamps; from far and near to being within easy reach, video chatting, and knowing everything about the world with just a click of a mouse. .
We are happy, we are lucky. We have caught up with an era of rapid development of science and technology, an era full of high technology. This is not only because our ancestors chose development during evolution. Progress also includes everyone's unremitting efforts and hard work. How many hard-working scientists we have today have exchanged their wisdom and even their lives for it.
Because of Faraday, our lives are surrounded by various electrical appliances; because of Darwin and Mendel, we can better understand and recognize ourselves; because of Bian Que, because of Hua Tuo, because of Li Shizhen, our lives can be protected.
Isn’t everything around us bought by them for us? Life is so comfortable, life is so pleasant, life is so wonderful, our average life span is 30 years longer than in ancient times, and we don’t even have to leave home to visit relatives and friends. Aren’t these all benefits brought to us by scientific development?
So, technology changes history. When we discuss whether the development of science and technology has greater benefits or greater harms, there is no need to question it, because it is beneficial! Great profit! Great profit! Science and technology change history, yes, without the development of science and technology, our lives are unimaginable. Our days are dark and dark. It is the development of science and technology that saves us. It is science that saves us from the age of water and fire. We should respect him with awe. How can we duplicity say that scientific and technological development has many drawbacks?
Technology changes history, and knowledge changes destiny. We have entered the 21st century and an era full of high technology. Science has changed our lives, and science has changed our destiny.
"Knowledge is power." Why can we, the People's Republic of China, a huge country with a population of 1.3 billion, stand tall in front of the world? Because our technology is constantly developing! Our technology is constantly improving!
The benefits of technological development outweigh the disadvantages. This is an eternal theme!
Rebuttal
Friends on the other side of the debate, you always list the various disadvantages of science and technology. It seems that the development of science and technology only brings disasters to mankind, so why do we still emphasize that science and technology are The primary productive force? Why do humans continue to develop science and technology?
If there was no technology, we might still be in a primitive society. So what’s the use of a good environment?
When people are researching technology now, aren’t they also protecting the environment? So how can we say that researching technology will definitely damage the environment?
This does not mean that the harm is greater than the harm. Li, this is just an isolated phenomenon, because they did not use science and technology correctly. This does not deny the benefits that science and technology bring to mankind.
You said that the development of science and technology has brought about air pollution, you said that the development of science and technology has produced white garbage, you said that the development of science and technology has caused temperature warming... all things cannot be perfect, the brighter the The shadows become darker behind the place, but based on this, you conclude that technological development will do more harm than good? "Everything is different, everything is different." Times are different, and the problems encountered are also different. When it comes to air pollution, all provinces and cities have launched prevention plans; white garbage is treated in a unified way; car exhaust causes temperatures to rise. Scientists have also developed solar cars. . Look at now, solar water heaters, solar air conditioners, solar cells... environmentally friendly and economical solar energy has gradually entered thousands of households. Isn't this the development of science and technology?
Although there are disadvantages, compared with benefiting mankind, the concept of scientific and technological development of environmentally friendly homes is insignificant. As long as there are disadvantages, scientists will also find ways to solve them. We cannot stop eating because of choking, and the pace of scientific and technological development will not slow down for a moment. will stop. There is nothing wrong with the development of science and technology. It is beneficial to society. It is the only answer to this question! Just because technology has been advancing and science has been developing, cunning sophistry, general remarks, and unreasonable nonsense cannot change this truth. If you say that technological development does more harm than good, may I ask you, can you come to class within a week without taking a car, using gel pens, ballpoint pens, or fountain pens? Can you not watch TV, listen to the news, read newspapers, read books, or surf the Internet for a week? Can you go without eating the developed hybrid rice for a week? Don’t eat pasta? No drinks? You can't, you can't and you can't, because technology is closely related to you and inseparable from you! Let me ask you, if you write a letter to the chairman saying that it is recommended to stop all scientific research activities, will everyone send you flowers or just take photos of you?

Lee: We can go where we want to go, people are constantly exploring, and in the future the "Solar Center" society may be overturned. Nowadays, with the development and progress of science and technology, no one can enjoy what those historical figures cannot enjoy. Every new person is interested in this world. With the development of economy, the acceleration of people's life rhythm and the improvement of living standards, the amount of plastic used
Increased 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 by 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 It can then 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 in weight and soft; the surface spraying and shaping equipment to increase the strength make the produced catering supplies waterproof, oil-proof, and heat-resistant. 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 will 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 relatively low. The cost of each rice box is about 0.12 yuan, and the rice box without rice box and bowl costs about 0.12 yuan. , 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 is completed, 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.
20,000 square meters of standard factory buildings have 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 for 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, adding 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 resource
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 foamed 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 The government departments should provide sufficient industrial policy support and guidance, and get a good start, so that this emerging green environmental protection industry can develop healthily and sustainably. The industry has a different understanding, and we Look further 1: Benefit greatly
Scientific development that is in line with the scientific outlook on development still has more benefits than disadvantages
“One generation has its own ideas and ways of doing things, no matter what Old experience or new ideas, each has its own advantages and disadvantages. Whatever can stand the test of practice and conforms to the scientific outlook on development is correct and reasonable!"
Look at history, from printing to papermaking, from From word processors to the enjoyment of network information, people's intelligence can be deepened, which is the driving force of humanities; from the perspective of human spiritual value, technology has freed people from the shadow of poverty, and network technology information has brought about the fourth Thinking about democracy and human rights in Poland, from antibiotics to organ transplantation, from water conservancy and irrigation to the improvement of biological species, has alleviated crisis after crisis for mankind. When the development of science and technology brings about the deepening of human physiological, psychological and spiritual values , generalization and optimization, can we still say that the development of science and technology has inhibited the all-round development of people~
The most direct manifestation is medical treatment. Of course, we are now healthy people standing here and we can certainly say that there is no need to look back. Scientific development is harmful because it destroys the environment and loads the earth with a lot of unnecessary things. But for those patients who are struggling in pain, because there is no scientific development and no more advanced medical measures, how can we still face them? Do you say environmental protection comes first? Is life more important or environmental protection more important? . .
