Causes and examples of the great disadvantages of scientific and technological development

Positive argument: As for the debate about whether the development of science and technology is beneficial or harmful, friends agree that the advantages of the development of science and technology outweigh the disadvantages.

Compared with 654.38+ million years ago, the way of human existence will not change much. Compared with before 2000, there will not be much change before 3000; Compared with 500 years ago, there will not be much change 600 years ago. However, today's people are not the people they used to be. Even now, compared with 100 years ago, they are completely different. What has promoted the development of human history? What made mankind start a new way of life? 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 gives mankind this brand-new and beautiful life. Throughout the ages, which dynasty and generation did not attach importance to the development of science and technology? Looking back, the four great inventions are unique; Look at the astronomical calendar and marvel; Look at Zhaozhou Arch Bridge, which is beautifully designed; A glimpse of the oriental masterpiece compendium of materia medica: look at the value of pi, seven decimal places; Overlooking the Silk Road and developing the economy; Blue and white porcelain is very famous overseas. Scientific and technological development is the road to a strong country and the first driving force for the progress of the Chinese nation. How can we live a happy life today without science? Without science and technology, how can we have a comfortable material life and spiritual enjoyment? Without the progress of science and technology, how can you eat hybrid 2? How can I put on cotton-padded jacket and live in a tall building?

There is an argument on the other side: how many amazing changes have taken place in the world since mankind entered the 2 1 century. While people are delighted with the rapid development of science and technology, they have also experienced better anxiety and even disasters. In addition to the panic caused by the development of high technology, especially biotechnology, war and disease seem to directly bring mankind to the door of hell. The invasion of various viruses, the exhaust gas behind cars, the exhaust gas from factories and so on. Don't invade our beautiful home. Why are our homes threatened, why are trees cut down in large numbers, and why is the air not fresh? These are all kinds of criminal evidence brought by science and technology. Modern science and technology have brought us some comfort and convenience, but at the same time, they have also brought about a wide range of influences. How can human beings live comfortably without a beautiful environment? If people don't remedy their mistakes quickly, mankind will eventually be destroyed by science and technology.

There are two kinds of views: the ancient people were superstitious about ghosts and gods, and believed that human life was decided by heaven, and birth, illness and death were controlled by heaven; In modern times, people have proved that superstition is not desirable through the development of science and technology, and they should create their own lives through their own hands. In ancient times, many people were seriously ill, and doctors could do nothing but watch patients die painfully. But now, through the development of science and technology, most intractable diseases have been successfully cured, and people don't have to worry about getting sick. ..... The above example is just the tip of the iceberg of the case that scientific and technological development benefits mankind. The rapid development of science and technology is unimaginable to ancient people. Why do TV and newspapers talk about promoting the development of science and technology almost every day, because how is the dream of flying for thousands of years round? It is the development of science and technology; What makes communication convenient? It is the development of science and technology; Why can seriously ill people live a happy life again? It is the development of science and technology! If the development of science and technology is wrong, then why do inventors and scientists such as Galileo, Newton, Edison, Madame Curie and Einstein dedicate their precious lives to science? Why spend so much precious time on the "wrong" cause? Have they no judgment? Who thinks their death is worthless, and who thinks their contribution to science is meaningless?

Opposing point of view: the development of science and technology has brought benefits to our lives, which we do not deny. However, we believe that the disadvantages brought by technology outweigh the benefits. First of all, although cars are convenient for us to travel, the exhaust gas from archways has caused environmental pollution and affected human health. Second, the appearance of entertainment facilities such as television has brought convenience to people, but it has also virtually blocked the communication between people, which is weak. There is also the emergence of the Internet. There is no denying that some lawless elements have the opportunity to disrupt people's lives and wait for a series of side effects brought by your so-called high technology. How can you just sit back and watch?

Three arguments: of course, the development of science and technology has also caused some negative effects, but these effects should have been very small, but human beings are like a magnifying glass, magnifying these negative effects. If humans can consciously reuse plastic bags instead of littering them, will it cause such serious white pollution? If mankind can exploit resources exhaustively, will it cause the current shortage of resources? If humans can save water and factories don't illegally discharge pollutants, will it cause serious water shortage now? There are many such things. Some people not only don't introspect, but blindly point the responsibility at "technology". I feel ridiculous and desperate for these people.

The three arguments contradict each other: just now, what the other debater said was just a hypothesis. Please come back to reality and ask, if there is no obstruction from science and technology, why should we promote environmental protection now? Besides, the current network problem is exactly what everyone is worried about. Many teenagers who should be happy in the motherland have gone astray and embarked on the road of crime. You said that although the internet can facilitate us to find information, how can such a small advantage be compared with the future of the motherland?

Four arguments: However, the development of science and technology has more benefits. The launch of the rocket has fulfilled the century-old dream of China people, and the completion of the Bird's Nest Water Cube has fulfilled China's Olympic dream. Without technology, how can China people realize their dreams? Why do you want to grasp the problem of network?

Oppose the other side's four arguments: the other side thinks the network problem is very important. Teenagers are the flowers of the motherland, and the future of the motherland depends on teenagers. The internet has made teenagers confused, and how many teenagers can't extricate themselves from it? If the next generation of the motherland is addicted to the internet, how can they realize more dreams of the motherland? Excuse me, another debater.

A positive statement: we are happy, we are lucky, and 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 and progress in evolution, but also includes the unremitting efforts and hard study of all people. How many hard-working scientists have bought it with their wisdom and even their lives today. Because of Faraday, our life is full of all kinds of electrical appliances; Because of Darwin and Mendel, we can know ourselves better and know ourselves; Because of Bian Que, because of Hua Tuo and because of Li Shizhen, our life can be guaranteed. Didn't they buy everything around us? Life is so comfortable, life is so pleasant and life is so wonderful. Our average life expectancy is 30 years higher than that in ancient times, and we don't even have to go out to visit relatives and friends. Isn't this all the benefits of scientific development?

Contrary: In primitive times, human beings only needed resources on the surface of the earth to survive, and only needed biological resources such as streams, fruits on trees and grass seeds to entertain themselves. Later, tools appeared, and then breeding was carried out, and the resources were utilized to a depth of one foot. Later, coal mines, metals and other resources went down to the seabed of 100 meters, and then down to 5000 meters. When people make use of them, they speed up their quest for resources from the depths of the earth.

Argument: As long as we control science and technology, the earth will not be destroyed.

Four theories: science and technology are the primary productive forces, and high-tech and its industries have promoted the development of the national economy. It can be said that high-tech and its industry have become the locomotive of contemporary scientific and technological development. Science and technology have changed people's ideas, improved people's living standards and promoted the development of socialist civilization. Scientific development can reflect a country's economic development level and national economic literacy. Science and technology are the primary productive forces, the concentrated expression and main symbol of advanced productive forces. I said that to develop productive forces and improve economic benefits, we must first rely on the development of science and technology. From the perspective of productive forces, science and technology can constantly improve and update labor tools, improve the quality of workers and make full use of labor objects. In short, the development of science and technology can greatly liberate productive forces, even create new industrial sectors, and lead to the rapid development of the national economy. We must adhere to the strategy of rejuvenating the country through science and education, so that the economic growth mode can get rid of the extensive old road and turn to the track centered on improving economic efficiency. It is indispensable to pay attention to the quality and benefit of economic development TV in life. We can watch the news and learn about things at home and abroad; You can watch cartoons and relax; You can also not go to the scene to watch programs and performances; For example, when the Olympic mascots are announced, we can watch the broadcast at home. A series of technologies have really brought us benefits, so we insist that the development of science and technology has both advantages and disadvantages!

Four arguments against it: in today's society, science is developing rapidly and many high-tech products are constantly emerging. Computers, cars, dishwashers, washing machines ... have entered the lives of ordinary people. They do bring a lot of convenience to our lives, but at the same time they gradually lose the basic abilities of human beings. With computers, people no longer think with their brains, because they can do it with computers; With cars, people are no longer used to walking, walking, but driving for a ride; With the dishwasher, people no longer wash dishes by hand. Maybe one day, people will forget how to wash dishes. The development of science and technology is mixed. Happily, it provides the greatest convenience for our life. What is worrying is that one day computers will replace the human brain and machines will replace the hands. By then, the world will no longer be dominated by people who think they are smart, but machines invented by human beings! So I think: the development of science and technology will inhibit the all-round development of people!

Another example is airplanes, rockets, networks and satellites, which originally appeared for military wars. The same technology is used as an accomplice to the destruction of mankind while benefiting mankind. So we think that the disadvantages of scientific and technological development outweigh the advantages!

The development of atomic physics theory has enabled mankind to master nuclear energy technology, but it has also brought about the nuclear disasters in Hiroshima and Nagasaki, and brought about the "terrible peace" of mankind for 50 years. For the first time, mankind has the ability of self-destruction. In addition, there are endless nuclear accidents, among which Chernobyl in the Soviet Union is the most famous (please search online for specific data). The development of chemistry has given us unprecedented ability to transform nature, but our gunpowder and explosives have also hurt tens of millions of human compatriots. Our chemical synthesis technology has created things that do not exist in nature, but now we are also troubled by white garbage and poisoned by chemical pollution. Why are so many children suffering from leukemia in our country now? Very important factors are chemical adhesives used in home decoration and ozone-destroying freon. The development of petroleum exploration technology has greatly accelerated the pace of human progress. We have been able to fly faster than the speed of sound, but it has also brought too many wars and too much interference, and the earth began to catch a cold and have a fever. The development of biotechnology has given us the power to create life monopolized by God before, but it has also brought about ethical disorder. In short, scientific progress is always accompanied by corresponding drawbacks and dangers. Today, we must face up to these negative effects, otherwise we humans may eventually be destroyed in our own hands. It was found that the harm of freon to the ozone layer did not stop people from using refrigerators, but used other refrigerants. After discovering that carbon dioxide can produce greenhouse effect, human beings did not stop using related fuels, but signed the Kyoto Protocol to limit greenhouse gas emissions. The same examples are numerous, so your point of view is rational criticism. It is precisely because of rational criticism that human beings have survived from self-destruction again and again. This is your argument. The development of human beings always needs some people to play the role of critics, and the core of freedom of speech is to ensure the moral freedom of those critics and the right of human beings to obtain different opinions.

How many amazing changes have taken place in the world since mankind entered 2 1 century. While people are delighted with the rapid development of science and technology, they have also experienced better anxiety and even disasters. In addition to the panic caused by the development of high technology, especially biotechnology, war and disease seem to directly bring mankind to the door of hell.

The epidemic of SARS in 2003, including all the speculations about SARS, is directly related to the global problem that people are paying more and more attention to: biological safety. Biosafety is a scientific and technological system for detecting, evaluating, monitoring, preventing and treating biological hazards. It is a new frontier discipline that studies the influence of various biological factors on human health, and applies existing theoretical knowledge, technology, engineering design and equipment to prevent people, laboratories and the environment engaged in related work from being harmed by potentially infectious substances and biotoxic substances. Biosafety problems are at least manifested in the following aspects:

The great harm of infectious diseases

Infectious diseases, including human, animal and plant infectious diseases, especially human infectious diseases, are the most important biosafety issues. Infectious diseases are still the leading cause of death in the world. In China, infectious diseases still pose a serious threat to people's health and national security. The prevalence of SARS is a strong proof. In addition, infectious diseases such as hepatitis, tuberculosis and influenza are still prevalent 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 made unremitting efforts to ban biological weapons and made some progress. However, in the 2nd/kloc-0th century, the potential threat of biological weapons has greatly increased, and some countries and regions may continue to develop biological weapons. In addition, the rapid development of biotechnology has greatly increased the potential threat of biological weapons, and bioterrorism marked by the "anthrax incident" in the United States poses a real threat to international security. Yuan, head of the Department of Microbiology at the University of Hong Kong, was the first scholar to isolate coronavirus, and found that coronavirus variant was the pathogen of SARS. SARS virus belongs to RNA virus, which is easy to recombine with other virus genes and become a new virus. Moreover, many experimental results also show that the new virus produced in this way will be more toxic than the parent virus. Coronavirus can be found in many animals. This virus is easy to mutate and extremely dangerous. Therefore, Yuan believes that SARS virus has great potential to become the pathogen for manufacturing chemical and biological weapons other than smallpox.

Negative effects of biotechnology

The negative effects of biotechnology are as follows: first, unexpected security problems may occur when people develop and utilize biotechnology. Just as the environmental release of various genetically modified organisms is widely concerned about the harm to biodiversity. In addition, genetically engineered drugs, vaccines, genetically modified foods, gene therapy, etc. There may be similar problems. The misuse and unethical application of biotechnology may also bring great security risks. The study of somatic cell cloning 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 harm to national interests. The environmental release of genetically modified organisms poses a great threat to biodiversity.

Potential safety hazards in microbiology laboratory

Compared with other physical and chemical laboratories or other laboratories, the microbiology and biomedical laboratory is a special laboratory. Everyone who works in it and the surrounding environment in contact with it are at high risk of contracting infectious diseases or affecting health. Omissions and accidents in microbiology laboratory management will not only lead to infection of laboratory staff, but also cause environmental pollution and large-scale population infection. Accidents of accidental infection in laboratories at home and abroad are common. In serious cases, thousands of experimental animals have to be slaughtered, even leading to the death of laboratory staff.

At present, with the rapid development of biotechnology, biosafety has become a major proposition that affects the politics, economy, security and peace of the whole country and even the whole world. In recent years, especially after the "anthrax infection incident" in the United States, biosafety issues have attracted much attention at home and abroad, and biosafety terms often appear 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 biological safety and regard it as an integral part of national security.

With the development of economy, the acceleration of people's life rhythm and the improvement of living standards, the amount of plastics

Increasing day by day. From 65438 to 0996, the consumption of plastic packaging in China reached 2.43 million tons, with an average annual growth rate exceeding.

20%, especially in cities, main traffic routes and tourist attractions, plastic waste is increasing rapidly.

According to the survey, the annual output of domestic waste in Beijing has reached 3 million tons, of which waste plastics account for about 3%, increasing year by year.

The growth rate reached 48%. The content of plastic in garbage in coastal cities is higher, reaching 8- 10%. These wastes

If the proportion of plastic in garbage is calculated by volume, it has reached more than one third, and it has greatly increased.

The difficulty and cost of garbage disposal.

Because waste plastics are difficult to degrade for hundreds of years, if discarded in the natural environment, it will give mosquitoes, flies and

Bacteria provide a hotbed for survival and reproduction; If buried underground, it is easy to pollute groundwater and hinder plant roots.

The growth of strains destroys soil quality and affects crop harvest; If you burn with fire, it will produce a variety of toxic gases.

Body. "White pollution" has become a major public hazard that harms the social environment of China and seriously hinders the development of China.

Sustainable development of economy and environment.

At present, the annual consumption of disposable tableware in China is about10 billion, mainly foam plastic products, which should be banned.

To stop the production and sale of these disposable foamed plastic tableware, it is necessary to develop and produce its substitutes.

Articles and green disposable tableware came into being. Experts believe that the development of green disposable tableware

And production is becoming a new environmental protection industry in China.

In mid-February, the Ministry of Science and Technology, the State Economic and Trade Commission, the State Environmental Protection Administration and the Ministry of Railways jointly held the Green One.

At the second tableware technology development exchange meeting, the reporter interviewed the person in charge of China Rural Technology Development Center.

Wang Zhixue and the managers of several production enterprises.

Wang Zhixue said: At present, the green disposable tableware developed and produced in China can be divided into paper according to the types of raw materials.

Pulp, rice husk, rice straw and starch. At present, there are hundreds of enterprises in China that produce paper disposable tableware.

The annual production capacity is about 3 billion.

The raw materials of paper tableware are seriously polluted in the production process, with high cost, high strength, water resistance and moisture resistance.

Poor sex, therefore, its popularization and application have great limitations, and people naturally look to others.

Department, to benefit from science and technology. If rice husk is used as raw material to produce rice husk tableware, there are more than a dozen such tableware in China.

Enterprise type, the annual production capacity is about 65.438+0.5 billion; Straw tableware is mainly made of crop straw.

Raw materials, at present, there are more than a dozen domestic manufacturers, with an annual production capacity of 75 million; Starch tableware is potatoes.

Starch is the main raw material, which has good biodegradability and can be used as feed after recycling. In a word, this country is very interested in green.

The research and development of recycled tableware is very important, through scientific and technological research, spark plan, torch plan and other scientific and technological development

The exhibition plan gives strong support, and the production technology of green disposable tableware in many enterprises is relatively mature, with

Laid the foundation for industrialization.

Wuhan Far East Green World Group Co., Ltd. takes starch as raw material to tackle scientific and technological problems of green disposable tableware.

Close and develop companies whose economic benefits have begun to take shape. Su Xiaohai, president of the company, had a legendary experience:

Formerly majoring in arts and crafts in Hubei Institute of Light Industry, 1984 entered Wuhan University to study for a master's degree in philosophy.

After studying and working in Germany, environmental protection in Europe touched him greatly, so he went back to China to do it.

The concept of environmental protection industry. Su Xiaohai told reporters: I have studied arts and crafts and am an aesthete.

Tian's commitment to environmental protection such as green tableware stems from my initial understanding of beauty; And the extension of aesthetics

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

From 1992 to 1996, the recycled cardboard disposable tableware and reed pulp developed by Far East Green World Company.

Due to the low technology content, the production scale of molded tableware has not been expanded. 1996 Gong

The company sent staff to inspect the technical situation of biodegradable packaging products in the European market and thought that the production of plant starch should be developed.

Fully degradable disposable tableware may be a way to eliminate "white pollution". 1997, consisting of a batch of food

Specialists in products, chemistry and machinery, the company focuses on the development of fully degradable disposable catering supplies, among which

Included in 1997 national torch plan project.

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

Starch such as sweet potato and corn, which are rich in domestic resources, is used as the main raw material, rather than a single foreign starch with higher price.

Potato starch; 20% natural fiber is added into sweet potato starch raw material, which makes the tableware obviously stronger.

Degree, and then use the processing technology of food expansion to make the products light and soft; Surface spraying to increase strength

Processing and molding equipment makes the produced catering products waterproof, oil-proof and heat-resistant. Xiao Su

The sea made a vivid metaphor: it is like reinforced concrete in building materials, sweet potato starch is cement, and

The root of all kinds of hay and plants is steel bars, so the strength of tableware can be obvious.

Enhance.

The tableware products with starch as raw material produced by Far East Green World are entrusted to SGS in Germany for reference to international food.

According to the packaging standard test, hot water and hot oil stored at 100℃ for more than two hours will not deform at all.

Excellent temperature performance. Because starch and additives are natural plant raw materials, the product has excellent degradation performance. Tested by National Environmental Testing Center, it can degrade more than 90% in about 10 day, and can be completely degraded within one month.

According to reports, because the project uses plant starch and plant fiber, the cost is low, and everyone has rice.

The cost of boxes is about 0. 12 yuan, and the cost of uncovered lunch boxes, bowls and plates is about 0.07 yuan, which has a broad market prospect.

At present, Far East Green World Company plans to invest 654.38+0.6 billion yuan to build a large-scale fully degradable green disposable tableware production base with an annual output of 5 billion pairs of disposable chopsticks and 3.5 billion bowls, plates and boxes. After the completion of the project, the annual output value can be increased by 625 million yuan, and the new profits and taxes will be about 654.38+300 million yuan. The civil engineering of the base started in March this year, and a standard workshop of 20,000 square meters has been built. If the follow-up funds can be guaranteed, the output is expected to reach the end of 1.999. Su Xiaohai said: Our scientific and technological advantages are obvious, and so are the social benefits that can be created in the future: disposable sanitary chopsticks made of starch can completely replace disposable wooden chopsticks, and this alone can save the country nearly 500,000 cubic meters of wood resources every year; If the group can reach its production capacity, it is estimated that it will use more than 200,000 tons of sweet potatoes every year and process them into more than 654.38 million tons of starch raw materials, which will also help more than 654.38 million people get rid of poverty in poor areas and promote the development of agricultural industrialization in old areas.

In the past few years, Shantou Heng Lv Industrial Co., Ltd. began to develop green disposable tableware made of rice husk.

I also had the ability to produce on an industrial scale before. The disposable packaging containers made of rice husk, especially the food packaging utensils used in supermarkets, produced by the company have been put on trial sale in Japan, Taiwan Province Province and the United States.

Land.

The green disposable tableware produced by Heng Lv Company is made by crushing and sieving rice husk and then mixing it with several edible ones.

The organic polymer adhesive is mixed with water, and then made into dishes, bowls and other utensils with different shapes by stamping, drying and spraying.

The general manager of Kyrgyzstan Commercial Co., Ltd. said: Disposable tableware is made of rice husk, which is not only owned by our country.

The source is abundant and inexhaustible, and it can be quickly degraded in the soil after use, killing two birds with one stone.

At present, Heng Lv Company has a production line running, with an investment of about 9.8 million yuan and a production capacity of 400,000 yuan.

Tableware/day, currently reaching 200,000 tableware/day. The annual output value is about 36 million yuan, the expected payback period is about one and a half years, and the investment profit rate is about 30%. The production technology and product quality have passed the technical appraisal organized by Guangdong Science and Technology Commission and the inspection by the food hygiene department. It is reported that in order to better market its products and scale operation, the company plans to set up a group company in the near future and invest in technological transformation to make the production line more automated.

According to the introduction of green tableware technology development exchange conference sponsored by the Ministry of Science and Technology, July 1998, Wen Jia.

Vice Premier Bao specifically proposed to solve the "white pollution" along the Yangtze River, Taihu Lake and railways in one year at the Taihu Lake Basin Water Pollution Prevention and Control Work Conference, and asked the relevant departments in the State Council to focus on three tasks: First, strengthen management and prohibit littering; Second, stop using disposable foamed plastic tableware; The third is to develop and mass-produce substitutes as soon as possible. 165438+1October 14 Vice Premier Li Lanqing also raised the issue of popularization and application of foam plastic tableware substitutes at the 12 national patriotic health campaign committee working conference. It seems that the green disposable tableware has attracted great attention of the central leading comrades and relevant departments of science and technology, environmental protection and so on. As a new environmental protection industry, it can be said that it is born at the right time. Now, we need scientific and technical personnel who can climb the peak of science to continue to engage in research and development, entrepreneurs who know how to operate and manage to intensify technological innovation and market development, and far-sighted financiers and venture capitalists to know this pearl and invest enough money in the industrialization of green disposable tableware.

Most enterprises engaged in the development and industrialization of green disposable tableware in China have small production scale and poor wind resistance.

Inspur's ability is weak, and many of them are private enterprises. It needs the support and guidance of government departments in industrial policies to make a good start and make this emerging green environmental protection industry develop healthily and continuously.

1, on the other hand, the reason why earthquakes occur more and more frequently is not the over-exploitation of human beings, which has changed the original geological material structure, such as the exploitation of oil and groundwater and the burning of coal, which should make the crust lose its due elasticity in motion. Oil, natural gas and coal are all parts of the earth. We pump them out, so the interior of the earth becomes more and more empty. Just like a snowman, the structure of the snowman will change after the snow changes from solid to liquid. Many places in the world, such as Sichuan and Guatemala, have begun to have big holes and large-scale collapse, which is an obvious manifestation. So the 5. 12 earthquake means that the disadvantages of science and technology outweigh the advantages.

Your opponent, you said that the high-rise building we live in is only possible with the development of science and technology, but from a practical point of view, the high-rise building is also worrying. When the airflow passes through the skyscraper, it will produce an airflow vortex, which will make the top of the building slightly shake, make people feel uncomfortable and lead to the damage of the building structure. Judging from its social impact, there will be a "canyon effect" where skyscrapers gather. This effect will make the wind speed on the surface of the building too fast, which will cause the glass curtain wall of the building to be destroyed like an avalanche and seriously endanger the safety of pedestrians. At the same time, the glass curtain wall will also produce light pollution, causing litigation. In addition, due to the elevator height and water pressure restrictions, fire safety is also a problem. Therefore, for the sake of safety, the windows of most skyscrapers are closed all the year round, and the offices in the building rely on air conditioners to adjust the room temperature and air all the year round. In this way, building diseases such as "tall building syndrome" have emerged. The momentum of the development of new buildings to high altitude is declining sharply. The current skyscraper craze can be regarded as the phenomenon of "regional difference" and "time difference" of architectural culture caused by the unbalanced development of the world economy. With the development of science and technology, we live in high-rise buildings, but high-rise buildings make it difficult to return huge investments; The risk factor is higher than that of ordinary buildings; It is not conducive to ecological and environmental protection issues, so can it be said that the disadvantages of scientific and technological development outweigh the advantages?

Today we are discussing whether the disadvantages of scientific and technological development outweigh the advantages or the advantages outweigh the disadvantages. This doesn't mean that we don't use everything related to technology. The development of science and technology does more harm than good, and it does not conflict with eating rice, using pens and notebooks. What's more, there is rice without technology, and there is paper in ancient China.

Then why don't other debaters say that the development of science and technology makes the physical quality of human beings worse than before? With the development of science and technology, cars, trains, planes and other means of transportation have appeared, which has made great changes in human daily life. Humans no longer always rely on their own legs. Therefore, the physical quality of human beings cannot be compared with the past. Xiang Yu in the past, it is impossible to "pull out mountains and rivers" in today's society. If this situation continues to develop, it may make people's limbs atrophy and make human beings appear in new forms. The development of science and technology has brought all kinds of new germs. The lethality of many germs has far exceeded the destructive power of previous germs. This is because the rapid development of medical science and technology has accelerated the mutation of virus, so that the development speed of science and technology can not keep up with the mutation speed of virus. Maybe one day mankind will die of a great plague. Since all the new diseases are brought by the development of science and technology, can we say that the development of science and technology keeps us from waiting for death?

The development of atomic physics theory has enabled mankind to master nuclear energy technology, but it has also brought about the nuclear disasters in Hiroshima and Nagasaki, and brought about the "terrible peace" of mankind for 50 years. For the first time, mankind has the ability of self-destruction. In addition, there are endless nuclear accidents, among which Chernobyl in the Soviet Union is the most famous (please search online for specific data). The development of chemistry has given us unprecedented ability to transform nature, but our gunpowder and explosives have also hurt tens of millions of human compatriots. Our chemical synthesis technology has created things that do not exist in nature, but now we are also troubled by white garbage and poisoned by chemical pollution. Why are so many children suffering from leukemia in our country now? Very important factors are chemical adhesives used in home decoration and ozone-destroying freon. The development of petroleum exploration technology has greatly accelerated the pace of human progress. We have been able to fly faster than the speed of sound, but it has also brought too many wars and too much interference, and the earth began to catch a cold and have a fever. The development of biotechnology has given us the power to create life monopolized by God before, but it has also brought about ethical disorder. In short, scientific progress is always accompanied by corresponding drawbacks and dangers. Today, we must face up to these negative effects, otherwise we humans may eventually be destroyed in our own hands.
