There is going to be a debate in my sister's school: whether the development of science and technology is beneficial or harmful, my sister is in favor (supporting the development of science and technology), but there are no examples to fully explain it. Counterpart:

Although the development of science and technology is important, it can't be developed on the premise of reasonable and normal use. The development must first purify the mind. Only when no one's mind and soul are developed and improved, the high-tech development can be beneficial to human development and natural harmony forever!

It is said that each of us has set our sights higher and farther, which makes us see what is higher in the distance, explore and pursue, and ignore what we should do in front of us. Just like some monarchs in history who want to live forever, drugs are used to treat diseases, and as a result, they blindly invest in something impossible, which harms themselves and the people, and there is a macro scene that people see in movies now. For example, if every

technological development brings convenience to people, it also brings disaster. Leon: We can go where we want to go. People are constantly exploring, and in the future, the association of Sun Center may be overthrown. With the development of science and technology, no one can enjoy what those historical figures can't. Every new person has a different understanding of the world, and our eyes are farther!

Examples of the disadvantages of scientific and technological development outweigh the advantages

1. Environmental pollution. This is the most direct and obvious disadvantage.

2. The accelerated extinction of species. This is caused by environmental pollution and human killing. It also belongs to the disadvantages of scientific and technological development.

3. Personal safety is increasingly insecure. Now there are tens of thousands of criminal acts every day on average. Most of their criminal means are related to. It is even more difficult for ordinary people to prevent. From the Second World War, we can already see that with the development of science and technology, the damage and losses caused by the current war are far from being comparable. It may even lead to the fate of human extinction.

4. The physical quality of human beings is not as good as before. With the development of science and technology, the emergence of various means of transportation such as gas cars, trains and airplanes has greatly changed human daily life. Human beings are no longer always dependent on their own legs, so the physical quality of human beings can't be compared with before. In the past, Xiang Yu's "pulling the mountains and rivers to cover the air" is impossible to appear again in today's society. If this situation continues to develop, it may make people's limbs shrink and make human beings appear in a new form.

5. Various emerging germs continue to appear. 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 variation of viruses, so that the development speed of science and technology has failed to keep up with the variation speed of viruses. Perhaps one day mankind will perish from a major plague. < P > You said that the development of science and technology has led to the high-rise buildings where we live, but from the practical point of view, high-rise buildings are also worrying. When the airflow passes through the skyscraper, it will produce airflow vortex, which will cause the top of the building to shake slightly, which will make people feel uncomfortable, and will lead to the damage of the building structure. Judging from its social impact, there will be a "canyon effect" where skyscrapers cluster. 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, which will seriously endanger the safety of pedestrians. At the same time, the glass curtain wall will also produce light pollution, which will cause litigation. In addition, fire safety is also a difficult problem due to the limitation of elevator height and water pressure limit. Therefore, for the sake of safety, the windows of most skyscrapers are closed all year round, and the offices in the building rely on air conditioners to adjust the room temperature and air all year round. In this way, building diseases such as "tall building syndrome" came into being. The momentum of new buildings developing to high altitude is declining sharply. At present, the skyscraper craze can be regarded as a phenomenon of "regional difference" and "time difference" in architectural culture due to the imbalance of world economic development. 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 problems such as ecology and environmental protection, so can it be said that the development of science and technology does not do more harm than good?

3. Debate friends of the other side Today, we are discussing whether the development of science and technology does more harm than good or does more harm than good. It doesn't mean that we don't need everything related to science and technology. The development of science and technology does more harm than good, and it doesn't conflict with eating rice, using pens and notebooks. What's more, rice existed without science and technology, and paper existed in ancient China.

4 Why didn't the other debater say that it was the development of science and technology that made the physical quality of human beings worse than before? With the development of science and technology, the appearance of cars, trains, planes and other means of transportation has greatly changed human daily life, and human beings no longer always rely on their own legs. Therefore, the physical quality of human beings can't be compared with that of the past. In the past, it was impossible for Xiang Yu to "pull out the mountains and rivers" in today's society. If this situation continues to develop, it may shrink people's limbs and make human beings appear in a new form. The development of science and technology has brought about various emerging 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 viruses, so that the development speed of science and technology has failed to keep up with the mutation speed of viruses. Perhaps one day mankind will die of a major plague. Since the new diseases are brought about by the development of science and technology, can it be said that the development of science and technology has kept us from waiting for death?

Let's compare today's life with that of 1, years ago. We are supreme. Comparing today with thousands of years ago, we are condescending; Comparing today with hundreds of years ago, we are happy and comfortable; Let's argue with each other today that the reason why earthquakes occur more and more frequently is not that human overexploitation has changed the original geological material structure, such as the extraction of oil, groundwater and the burning of coal, which should make the crust lose its due elasticity during the movement. It is oil, natural gas and coal that are all components of the earth. We pump them out, so that the interior of the earth becomes more and more empty. Just like a snowman, the structure of the snowman will change after the snow turns from solid to liquid. In many places in the world, such as Sichuan and Guatemala, big holes and large-scale collapses began to appear, which is an obvious manifestation. Therefore, the 5.12 earthquake means that the disadvantages of science and technology outweigh the advantages.

1 The rapid development of science leads to the extinction of animals. Without animals, the food chain will be broken, and human beings will not survive, and will become extinct like dinosaurs.

2 scientific development has harmed the earth, resulting in more and more natural disasters.

3 Although 212 is only a prediction, it is still true. Because the ozone layer does not destroy human beings, they cannot live normally.

4 The natural environment is destroyed. Trees are supposed to purify the air. If trees are destroyed, there will be no fresh air.

1 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 Changqi, and brought about the "terrible peace" of mankind for 5 years. For the first time, mankind has the ability to destroy itself. 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 enabled us to gain 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 do so many children in our country suffer from leukemia now? The very important factors are the chemical binders used in home decoration and Freon that destroys the ozone layer. The development of oil exploration technology has greatly accelerated the pace of human progress. We have been able to fly at a speed exceeding the speed of sound, but it has also brought too many wars and too many disturbances, and the earth has begun to catch a cold and have a fever. The development of biotechnology gives us the power to create life which was monopolized by God before, but it also brings ethical disorder. In a word, the progress of science is always accompanied by corresponding disadvantages and dangers. Today, we must face up to these negative effects or we human beings may eventually be destroyed in our own hands.

2 Personal safety is becoming more and more insecure. Now, tens of thousands of crimes occur every day on average. Most of the criminal methods are related to the new technology. Especially, gun crimes are hard for ordinary people to guard against. From the Second World War, we can already see that with the development of science and technology, The damage and losses caused by the current war are far from comparable. It may even lead to the fate of human extinction.

3 The physical quality of human beings is far from what it used to be. With the development of science and technology, the emergence of various means of transportation such as gas cars, trains and airplanes has greatly changed human daily life, and human beings are no longer always dependent on their own legs. Therefore, the physical quality of human beings can't be compared with that of the past. In the past, Xiang Yu's "pulling the mountains and rivers to cover the air" is impossible to appear again in today's society. If this situation continues to develop, it may make people's limbs shrink and make human beings appear in a new form.

4 Various emerging germs appear constantly. 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 variation of viruses, so that the development speed of science and technology has failed to keep up with the variation speed of viruses. Perhaps one day mankind will perish from a major plague.

5 With the acceleration of people's living pace and the improvement of living standards, the amount of plastics is increasing day by day. In 1996, the consumption of plastic packaging in China reached 2.43 million tons, with an average annual growth rate of more than 2%, especially in the garbage of cities, major traffic routes and tourist attractions. 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%, with an annual growth rate of 48%. The plastic content of garbage in coastal cities is higher, reaching 8-1%. The proportion of these waste

plastics in garbage has reached more than one third by volume, which greatly increases 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 provide a hotbed for mosquitoes, flies and bacteria to survive and breed; If buried underground, it will easily pollute groundwater, hinder the growth of plant roots, destroy soil quality and affect crop harvest; If it is burned by fire, it will produce a variety of toxic gases. "White pollution" has become a major public hazard that harms China's social environment and seriously hinders the sustainable development of China's economy and environment.

6 the development of science and technology is based on destruction and continuous summary. Therefore, its development and further deepening will definitely bring some negative impacts on the environment. Looking at the long history, the damage will be more serious with the development of science and technology!

7 In today's society, cars can be seen everywhere, which not only does great harm to people's body and mind, but also pollutes the atmosphere. All the creatures in the world are infringed by this "scientific and technological product" to some extent. It is selfish for human beings to take care of the safety of other creatures on earth for their own convenience. To say the least, cars are also very harmful to human beings. Freon in air conditioners and refrigerators also destroys our precious atmosphere. The so-called high-tech products make the world dirty and rigid. The free land is swallowed up by human beings little by little, the free sky is shrunk by human beings little by little, and the free sea is occupied by human beings little by little.

8 At present, with the rapid development of biotechnology, biosafety has become a big proposition that affects the politics, economy, security and peace of the whole country and 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 are often seen in government or non-governmental organization documents and in various media. The global epidemic of SARS will undoubtedly make countries all over the world pay more attention to biosafety and regard it as an integral part of national security.

9 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 their health. Omissions and accidents in the management of microbiology laboratory can not only lead to the 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 not uncommon. In severe cases, thousands of experimental animals have to be slaughtered, even leading to the death of laboratory staff.

1 when people develop and utilize biotechnology, unexpected safety problems may occur. Just as the harm to biodiversity caused by the environmental release of various genetically modified living organisms is widely concerned at present. In addition, genetically engineered drugs, vaccines, genetically modified foods, gene therapy, etc. may have similar problems. The misuse and unethical application of biotechnology may also bring great security risks. The research of somatic cell cloning is a prominent example.

11 Like any industrial product we use, air conditioning will inevitably bring a certain burden to our environment. A few years ago, the impact of air conditioning on nature mainly focused on the destruction of the earth's ozone layer by refrigerants, but in recent years, due to the development of refrigerant renewal, this is no longer the main factor. The impact of air conditioning on nature in the future is still reflected in the field of energy consumption, which has accounted for a large proportion of the total energy consumption of our life and industry. The exploitation of energy and the release of a lot of heat to the atmospheric environment have caused a great burden to our natural environment, which is the major problem we have to solve for a long time.

12 Challenges to ethics: Up to now, the issue of cloning has not been beneficial to human beings, such as the advantages of treating diseases, but on the contrary, the issue of cloning has brought great challenges to human ethics; There is also damage to human security: science and technology are accompanied by high risks, and large-scale tragedies often occur in the process of scientific and technological development, such as Hiroshima atomic bomb and Chernobyl nuclear leakage

13 from scientific development to globalization, from globalization to globalization, such as cultural loss and cultural aggression under economic strength; From globalization to the change of ideas, it is best to give some examples, such as the lost generation in the United States, which consumes a lot of limited material resources on the earth.

As mankind enters the 21st century, the world has undergone many amazing changes. While people are delighted with the rapid development of science and technology, they have experienced better uneasiness 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 gate of hell.

The epidemic of SARS in p>23, including all the speculations about SARS, is directly related to the global issue that people are increasingly concerned about: biosafety. Biosafety is a scientific and technological system for the detection, evaluation, monitoring, prevention and treatment of biological hazards, and it is to study the effects of various biological factors on human health.
