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?
Q: Is the development of science and technology beneficial or harmful? Without a doubt, of course it is Lida! What is the explanation? No need to explain! China's 8,000-year history of civilization is irrefutable evidence. History has been changing and technology has been developing. Humans learn to use or cook food from primitive life, from relying on nature to thriving, from unarmed to metallurgical smelting. This is not progress, this is not development? If the disadvantages outweigh the advantages, then why do human beings choose progress in unison? Only progress can make tomorrow better!
It is sad for a person not to make progress, a country is declining without progress, and a world is dark without progress. Only by continuous progress can human life be sublimated. Man is small and fragile. He has no huge body, no strength like an ox, and no hard shell like a turtle. However, God has given mankind a clever brain and a pair of hard-working hands. Instead of enjoying success, human beings have chosen to make continuous progress and stand at the top of today's food chain.
Let's compare today's life with that of 10 million years ago, and 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; Comparing today with tomorrow, the future is bright. For thousands of years, it has changed from a carriage to a car, train and plane; From kerosene lamps to incandescent lamps, neon lights and energy-saving lamps; From the ends of the earth to close at hand, video chat and mouse know everything about the world.
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 lives 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?
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! 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. There is nothing wrong with the development of science and technology, that is, to benefit greatly. This is the only answer to this argument! Just because science and technology have been advancing and science has been developing, cunning sophistry, generalization and unreasonable entanglement can't change this truth. If you say that the development of science and technology does more harm than good, can you come to class without a car, gel pen, ballpoint pen and pen within a week? Can you stop watching TV, listening to the news, reading newspapers, reading books and surfing the Internet for a week? Can the developed hybrid rice not be eaten for a week? No spaghetti? Don't drink? No, no and no, because technology is closely related to you and inseparable from you! Now if you write to the chairman and suggest stopping all scientific research activities, will everyone send you flowers or the board of directors shoot you exclusively?
It is true that technology has changed history. Without the development of science and technology, our life is unimaginable. Our days are dark. It was the development of science and technology that saved us, and it was science that saved us from the age of hydrothermal. We should respect him with awe. How can we say that the development of science and technology is full of drawbacks?
Science and technology change history, and knowledge changes destiny. We have entered the 2 1 century, an era full of high technology. Science has changed our lives, and science has changed our destiny. "Knowledge is power". Why do we, the people of China, a vast country with a population of 65.438+0.3 billion, stand tall in front of the world? Because our technology is constantly developing! Our technology is constantly improving!
The advantages of scientific and technological development outweigh the disadvantages, which is an eternal theme.
The development of science and technology has great disadvantages-science and technology not only brings convenience to mankind, but also sows the seeds of destruction.
Everything has advantages and disadvantages. I don't need to waste my breath on the benefits of technology. However, we often think that what is diluted or even ignored is its negative effects. Different from other things, the opposite of technology is as sharp as a blade and as sharp as a sword, which is what we often call a double-edged sword. Third, the high dependence on science and technology makes human beings eager to move. The subjective dependence caused by human's high trust in science and technology makes the sword wield its power at will, which directly leads to the power of science and technology to destroy human beings. When human beings sing a song of triumph for science and technology, please don't forget that science and technology can also give evil spirits the power of the devil.
1. computer: because of the computer and the network, there will be online games. So teenagers can't extricate themselves, neglect their studies and do nothing. Computers and television have caused our myopia. Without TV and computer, we might not be nearsighted.
2. Automobile: Although its arrival has brought great convenience to people, it has also brought great losses to people. Car noise, exhaust pollution and car accidents in cities have caused countless deaths and injuries. People still want to invent some cars that don't pollute the environment, but at the same time they waste resources. With the population expanding, if everyone has a car, is there still room for human beings to live? A man wrote an article. He simulated the future. Nowadays people only rely on high technology but are too lazy to do it. They got many diseases and caused human death. Some people may say, what should I do if I get sick without high technology? Then let me tell you, more people die from car accidents than from diseases every year. The emission of automobile exhaust has caused environmental pollution and seriously affected people's health.
3. Air conditioning: Like the industrial products 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 ozone layer by refrigerants, but in recent years, due to the development of refrigerant renewal, this is no longer the main factor. Reduce people's adaptability to the natural environment and reduce immunity.
4. Nuclear energy technology (atomic bomb): The development of atomic physics theory means that human beings have mastered nuclear energy technology. As we all know, the nuclear disasters in Hiroshima and Nagasaki in Japan have brought "terrible peace" to mankind for 50 years, and mankind has the ability of self-destruction for the first time. Nuclear accidents emerge one after another, among which Chernobyl in the Soviet Union is the most famous. With the development of chemistry, we have gained unprecedented ability to transform nature, but our gunpowder and explosives have also hurt tens of millions of human compatriots.
The appearance of entertainment facilities such as television makes the communication between people less and less, and human feelings are weak.
6. The physical quality of human beings is not as good as before. With the development of science and technology, the emergence of vehicles such as air cars, trains and planes has brought great changes to human daily life. Humans no longer always rely on their own legs, so the physical quality of human beings can't be compared with before. 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 technology has accelerated the mutation of the virus. So that the development speed of science and technology can't keep up with the speed of virus mutation.
7. Harm to nature: For nature, the development of science and technology is almost harmful. First of all, from the perspective of human beings, it has been very harmful since human beings came to this world, because human beings are selfish and have destroyed the natural ecological balance. Nowadays, the development of science and technology has brought convenience to human beings, but it is also harmful to human beings and nature, leading to the extinction of precious animals; Although cloning technology can save those endangered animals, it is still human beings, or human technology, that makes those animals endangered. In my opinion, the technology of cloning is just that human beings are making up for their mistakes.
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 more disasters. War and disease seem to directly lead mankind into the gates of hell.
Thanks to mobile phones, users' brains are often irradiated, which is very harmful to people's brains. According to statistics, when people use their mobile phones for more than 1 hour a day, their instantaneous memory will drop by 30%.
We have to argue about the pros and cons, not all the pros and cons, so some benefits in the development of science and technology can still be utilized. 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 by ourselves.
Another debater talked about the benefits of technology, but we don't deny the benefits of technology. Is it just that the other debater really thinks that water can carry a boat and also overturn it? Technology has brought convenience to mankind, but it has also planted the seeds of destruction. Science and technology 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. The so-called good medicine is good for the disease, because thinking about science and technology rationally and comprehensively can keep science and technology under the control of human beings all the time and will not harm human beings in turn. We must face up to these negative effects, otherwise we humans may eventually be destroyed by ourselves.
Through modern science and technology, some dirty information has been widely spread, which has brought terrible shadows to people. Isn't this the disadvantage of technological development? It is precisely because of the development of science and technology that the pure heart of human beings will be covered by interests. Isn't this the disadvantage of technological development? How good the technology will be in the future, but the word "will" in today's debate tells us to look at tomorrow from today, not from tomorrow.
To sum up our views, first of all, technology has brought convenience to mankind, but it has also planted the seeds of destruction. Now everyone dares to say that science and technology are people-oriented. Is serving the people people people-oriented? Secondly, technology is deified, but people are instrumentalized, and everything is dominated by technology. Such examples abound around us. Technology was originally just a tool, but when it is deified and people are instrumentalized, such people are a kind of destruction. Third, science and technology are dominating the destiny of mankind with unprecedented power. The independence of scientific and technological development has long been beyond human control, which in turn dominates human beings. Technology is just a means, not an end. Only when we dare to admit the existence of this destructive trend can we tell you that the road is long, Xiu Yuan is Xi, and I will pursue it up and down.
1 The rapid development of science leads to the extinction of animals. Without animals, the food chain will break, human beings will not survive, and they will become extinct like dinosaurs.
Scientific development has damaged the earth and led to more and more natural disasters.
Although 20 12 is only a prediction, it is still true. Because of the destruction of the ozone layer, human beings can't live normally.
The natural environment was destroyed. Trees are thought to purify the air. If trees are destroyed, there will be no fresh air.

Hello, teachers and students. 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.

Our technology is constantly improving!
The advantages of scientific and technological development outweigh the disadvantages, which is an eternal theme.
Disadvantages:
1: Environmental pollution. This is the most direct and obvious disadvantage.
2. Species extinction is accelerating. This is caused by environmental pollution and human hunting. It also belongs to the disadvantages of scientific and technological development.
3. Personal safety is increasingly insecure. Now tens of thousands of crimes occur on average every day. Most of their criminal methods are related to the current new technology. Especially gun-related crimes, ordinary people can't prevent them. 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 emergence of vehicles such as air cars, trains and planes has greatly changed human daily life. Human beings are no longer always dependent on their own legs, so the physical quality of human beings is not comparable to that in the past. In today's society, it is impossible for Xiang Yu to "pull out mountains and rivers". If this situation continues to develop, it may make people's limbs atrophy and make people appear.
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 virus, so that the development speed of science and technology has not kept up with the mutation speed of virus. Maybe one day mankind will die of a great plague. With the development of economy, the acceleration of people's life rhythm and the improvement of living standards, the amount of plastic used by each newcomer is 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 of more than 20%, especially in the garbage of cities, main traffic arteries 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%, increasing year by year.
The growth rate reached 48%. The content of plastic in garbage in coastal cities is higher, reaching 8- 10%. The volume ratio of these waste plastics in garbage is more than one third, which greatly increases the difficulty and cost of garbage disposal.

With the development of science and technology, human civilization has taken a big step forward, from the previous carriage to the car, from the previous oil lamp to the electric light. ...
Now, people's lives are getting better and better. Use the telephone to speed up communication, use cars and motorcycles to speed up the pace of life, and use electric cookers and gas to cook delicious meals. ...
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.
Since the first computer appeared in the United States, people have given computers a glorious mission.
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. It seems to be the driving force to accelerate social development, weaving a net around the world with invisible chains, trapping development and life.
Science and technology is a weapon for human beings to overcome and transform nature and an important force to promote the development of social productive forces. Every development of science and technology is a leap in the history of human civilization and an epoch-making victory for human beings to conquer nature and self. In the early days of primitive society and slave society, it was precisely because of the casting of bronzes and the use of ironware that social wealth doubled and caused changes in social form. In the industrial revolution in the18th century, it was precisely because of the wide application of steam engine technology that the industrial revolution entered a new stage, thus doubling the wealth of the capitalist world. After the Second World War, it was precisely because of the influence of the third scientific and technological revolution, which mainly focused on electrical appliances, that it greatly promoted the economic recovery of post-war capitalist countries and the substantial economic growth of socialist countries, and promoted the rapid increase of social wealth and the fundamental improvement of people's lives. So the advantages of scientific and technological development are obvious.
Whether people realize it or not, science and technology have deeply influenced our daily life and played an indispensable role in economic and social development. Especially since the 20th century, with the rapid development of science and technology, especially computer network technology and electronic information technology, expensive luxuries such as mobile phones and computers have entered the homes of ordinary people and become necessities of our lives. Imagine how we can keep in touch with our relatives at will without mobile phones. If there is no internet, how can we talk with friends in foreign countries? Without HDTV technology, how can you enjoy gorgeous Hollywood movies? Of course, we must also admit that science and technology have changed our way of life and culture to some extent. Nowadays, more and more young people have accepted fashionable lifestyles such as e-commerce and distance education, and even online dating has become a trend.
It is precisely because of the importance of science and technology that our national leaders have repeatedly proposed to vigorously develop science and technology. Comrade Deng Xiaoping once pointed out that science and technology are the primary productive forces, thus establishing the important position of science and technology, taking the development of science and technology as a basic national policy of our country, increasing the capital investment in scientific and technological development, improving the hard and soft environment for scientific and technological development, and making our country make great progress after the reform and opening up and step into the forest of powerful countries in science and technology. However, we should also be soberly aware that there is still a big gap compared with developed countries such as the United States, Germany and France, and many technologies are restricted by developed countries. Therefore, we must catch up and catch up.
As a member of the current society, we should not only realize the importance of science and technology, but also study science and technology hard, arm our minds with science and technology, have the courage and determination to devote ourselves to science, and use science and technology to develop the broad mind of all mankind. More importantly, we should also educate our future generations to love and respect science.
What exists at present has its rationality.
Science is so important to people's lives. Not only the TV sets, computers, cars and mobile phones that accompany us day and night are closely related to science, that is, the food we eat, the water we drink, the clothes we wear and the electricity we use, but also the instruments and medicines used to see and treat diseases. What has nothing to do with science? If we want to live, we can't leave science for a moment.
People can't live without science, and development can't live without science. Without the word "science", we can't move forward well and quickly.
Our understanding of the law of development has a deepening process. Since the reform and opening up, we have vigorously promoted the rapid economic development, which has brought about significant changes in urban and rural areas and improved people's living standards. However, on the road of rapid development, the constraints of population, resources and environment, the imbalance of urban and rural, regional, economic and social development, and the contradiction between social resources and wealth distribution are all kinds of problems before us. Therefore, at the critical stage, the CPC Central Committee inherited and developed the important thoughts of the three generations of central leading collective of the Party on development, put forward Scientific Outlook on Development, and further answered the questions of "for whom", "on whom" and "how". From "development" to "scientific development" and from "sound and rapid development" to "sound and rapid development" is a qualitative leap in understanding the law of development, which will not only determine our tomorrow, but also have an impact on the future of the world.
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, and earnestly pay attention to the quality and efficiency of economic development.
The essence of today's world competition is economic and technological competition. Economy is the foundation and technology is the leader. Economic development is conducive to enhancing China's comprehensive national strength and enabling China to participate in international competition on a larger scale and at a higher level.
I think the most important thing in this debate is not to list all kinds of disadvantages brought by science and technology to mankind, because if your eyes are only fixed on the disadvantages, then the other party is likely to seize this point and attack you: your opponent, you always list all kinds of disadvantages of science and technology, as if the development of science and technology has only brought disasters to mankind, so why are we still emphasizing that science and technology is the primary productive force now? Why should mankind continue to develop science and technology?
