Advantages and disadvantages of science and technology to national development
Now, people's lives are getting better and better. Speed up communication by telephone, speed up the pace of life by cars and motorcycles, and cook delicious meals with rice cookers and gas ...? Television is indispensable 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, you can watch the broadcast at home. ? Computers are more and more widely used in all walks of life. We sent a letter to Brazil in Haining, and it only took a few seconds for the other party to receive it. We can chat and play games with friends and relatives all over the world online. You can watch news, movies and listen to music online. You can listen to the teacher in class, find information, shop at home, have medical treatment and give first aid. ...
It can be said that technology is closely related to us. With this advanced technology, our life is faster, more convenient and more colorful.
So the advantages of scientific and technological development are obvious.
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? 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?
Therefore, science and technology change history, and we don't need to question whether the development of science and technology is beneficial or harmful, because it is beneficial! Rita! You said that the development of science and technology has brought air pollution, you said that the development of science and technology has produced white garbage, and you said that the development of science and technology has caused the warming of the temperature ... Everything can't be perfect, and the darker the shadow behind the brighter place, but on this basis, you can draw the conclusion that the disadvantages of science and technology development outweigh the advantages? Different times lead to different problems. Except air pollution, all provinces and cities have put forward prevention plans. White garbage, unified treatment; Automobile exhaust causes the temperature to warm, and scientists have also developed solar-powered cars. Look at now, solar water heaters, solar air conditioners, solar cells ... environmental protection and energy-saving solar energy are gradually entering thousands of households. Isn't this the development of science and technology?
Although there are disadvantages, it is irrelevant compared with the scientific and technological development concept of benefiting mankind and protecting home. As long as there are drawbacks, scientists will try to solve them. We can't stop eating because of choking, and the pace of scientific and technological development will not stop for a moment. ? From the perspective of "benefits", some reasons may be put forward: (1) The invention of these means of transportation, such as cars, makes people travel more convenient and saves time and effort. (2) The invention of telephone and mobile phone makes people's communication more convenient. (3) Computers and faxes have liberated people from heavy work, and the emergence of the Internet has broadened people's horizons. ...
You see, people's lives are getting better and better now. Speed up communication by telephone, speed up the pace of life with cars and motorcycles, and cook delicious meals with rice cookers and gas. Can you say that this is not due to technology?
Besides, TV is indispensable in life. We can watch TV news and learn about domestic and international affairs. You can watch cartoons and relax; You can also not go to the scene to watch programs and performances; For example, the Olympic mascot has been announced, and you can watch the broadcast at home. Where else did you get the extra-curricular knowledge? ? l？ Computers are more and more widely used in all walks of life. We sent an email from Shilong to other places, and it only took a few seconds for the other party to receive it. We can chat and play games with friends and relatives all over the world online. You can watch news, movies and listen to music online. We can listen to the teacher's class, look up information and shop at home ... It can be said that technology is closely related to us. With this advanced technology, our life is faster, more convenient and more colorful. Facts have proved that the appearance of this modern tool not only proves that science and technology have entered a new platform, but also proves that communication between different regions of the world cannot be separated from it.
Against: Species extinction is accelerating. This is caused by environmental pollution and human hunting. It also belongs to the disadvantages of scientific and technological development. In that case, the kitchen knife will hurt people. We don't need a kitchen knife Let's learn karate and cut vegetables! The indiscriminate killing of human beings has nothing to do with technology, but the chief culprit is human greed. After all, guns don't kill animals by themselves. You can't blame everything on technology. Just want to compare the carrier to a horse, people are coachmen, and the carriage behind them is loaded with goods, that is, technology. If the horse goes in the wrong direction, that is, people develop technology in a bad direction, will the coachman whip the horse or play with technology? This is a simple example, but it shows that the quality of the environment has nothing to do with technology, but with where human beings use technology. It is a double-edged sword, on the one hand, it can crush ignorance and backwardness, on the other hand, it may bring endless disasters to mankind. It is good for you to do good, but if you do bad, the result will be different. In addition, if there is no hybrid rice, everyone will eat bark for half a year. Without penicillin, everyone will get tuberculosis? Will the development of science and technology destroy the environment?
On the contrary, all kinds of new germs appear constantly, and 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 perish because of a great plague.
Of course, the advantages outweigh the disadvantages; The reasons are manifested in many aspects: from the medical point of view, the emergence of various modern technologies and laser surgery has saved many people's lives; Astronomy: the invention of artificial earth satellites and spacecraft, such as meteorological satellites, can accurately predict future weather changes and provide convenience for human production and life; In terms of human life, various electrical appliances make people's lives very comfortable, such as air conditioning, which is warm in winter and cool in summer. Of course, scientific progress is inevitably accompanied by negative effects, but the positive side accounts for the vast majority after all.
Grandpa Deng said that "science and technology are the primary productive forces", and President Jiang and President Hu repeatedly stressed the need to vigorously develop science and technology and build China into a powerful country in science and technology.
1. greatly improved social productivity. 2. Promote the harmonious development of society. 3. Promoted the development of human civilization.
4. Improve people's living standards and quality of life. 5. It promotes economic and social development and improves material quality.
6. Make the country more prosperous and the people richer and happier.
Disadvantages:
Computer: Because of computers and networks, there are online games. So teenagers can't extricate themselves, neglect their studies and do nothing.
Car: Because of the population expansion, if everyone has a car, is there still room for human beings to live? Nowadays, cars can be seen everywhere, which not only does great harm to people's body and mind, but also pollutes the atmosphere. All living things 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.
1, environmental pollution. This is the most direct and obvious disadvantage. The extinction of species is accelerating. This is caused by environmental pollution and human hunting. It is also a disadvantage of scientific and technological development. 3. Personal safety is increasingly insecure. There are now tens of thousands of crimes on average every day. Most of their criminal methods are related to the current new technology. Especially gun-related crimes, ordinary people are even more difficult 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. Human's physical quality is not as good as before. With the development of science and technology, the appearance of vehicles such as air cars, trains and planes has greatly changed human daily life, and human beings no longer always rely on their own legs. Therefore, the physical quality of human beings cannot be compared with the past. In today's society, it is impossible for Xiang Yu to "pull out mountains and rivers". However, if this situation continues to develop, it may make people's limbs atrophy and make people appear new forms. 5. All kinds of emerging germs appear constantly, and 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 the virus, so that the development speed of science and technology has reached.
From the perspective of "great harm", some reasons may be put forward: (1) The emission of automobile exhaust has caused environmental pollution and seriously affected people's health. (2) The appearance of entertainment facilities such as TV makes the communication between people less and less, and the human feelings are weak. (3) The emergence of the Internet has given some people the opportunity to disrupt people's production and life ...)
Just now, the other debater made two mistakes: first, the other debater did talk about the benefits of technology, but we don't deny the benefits of technology. It's just that the other debater really thinks that water can carry a boat and overturn it? Second, the other debater said that human beings are rational, but rationality does not mean that they will not perish. Below I will demonstrate our proposition from the development trend of modern science and technology. First, the development of science and technology is moving from individual trend to national trend and social trend. Personal pursuit and dependence on scientific and technological life is not a big problem. The problem is that this pursuit and dependence is becoming a national trend and social trend in a unique form of value. Science and technology have become the only correct direction in the world, and all ideas that run counter to it must make way for it. ? Second, the destructive trend of science and technology is manifested in the deification of science and technology and the instrumentalization of nature. It is technology that makes people no longer feel that they are part of nature. It is science and technology that makes human beings feel that they have a new god in their hands and constantly tool nature. However, when the natural order is broken, where will mankind stand?
(Counterparty): Just now, another debater blamed all the mistakes on science and technology, which was one-sided and did not really understand the relationship between science and technology and human beings. Technology is not water, and human beings can control it. Everything has its negative side. ? Next, I will explain our views from a realistic perspective. First, the development of high technology has made mankind gain unexpected gains. According to Zhongxin. Com, the robot assisted minimally invasive surgery for the first time in China; Nature magazine reported that a cell-sized nano-cow was finally born. All these achievements brought by science and technology have pushed mankind to a more prosperous starting point. Secondly, to solve our existing problems with high technology, there is no doubt that with the continuous development of science and technology, many problems will be solved, from garbage to energy crisis. Third, the level of scientific and technological development of mankind in a few years is believed to be unimaginable to all of us here. Just like the people who drilled fires in the Stone Age, they couldn't imagine. Now our world has natural gas and electricity. Human beings will not be destroyed by science and technology. On the contrary, science will only make human beings progress more and more.
