Poems about the advantages of scientific and technological development outweigh the disadvantages
With the development of human science and technology, people's lives have changed with each passing day
1. Environmental pollution.
2. Various emerging germs are constantly appearing. 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 perish from a major plague.
3. The species extinction is accelerated. This is caused by environmental pollution and human killing, which is also the disadvantage of scientific and technological development.
4. Personal safety is increasingly insecure. Now, Tens of thousands of crimes occur every day, and most of their criminal methods are related to the current new technology. Especially, gun crimes make ordinary people hard 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 comparable. It may even lead to the fate of human extinction.
5. Human physical fitness is not as good as before. With the development of science and technology, gas cars, The appearance of trains, planes and other means of transportation has greatly changed the daily life of human beings. Humans are no longer always dependent on their own two legs, so the physical quality of human beings now can't be compared with that before. In today's society, it is impossible for Xiang Yu to "pull out the mountains and rivers". If this situation continues to develop, it may make people's limbs shrink. Make mankind appear in a new form.
2. Examples of advantages of scientific and technological development outweigh disadvantages
Moderator: Hello, judges, debaters and audience. Today, our topic of debate is scientific and technological development: advantages or disadvantages. The society is developing and science and technology is progressing. Today, we see that scientific and technological development has brought us benefits, and at the same time, we also see that it has brought us some disadvantages. How should we view such advantages and disadvantages, whether they are great or great? Let's ask our debaters to give us a wonderful answer. First of all, let's debate each other's opening statements: regarding the debate on whether scientific and technological development is great or great, our debaters agree that the advantages of scientific and technological development outweigh the disadvantages. Compared with 1, years ago, the way of human existence will not change much; Compared with 2 years ago, there will not be much change before 3; 6 years ago, compared with 5 years ago, there will not be much change. However, today's people are not the same as before, even now, compared with 1 years ago, it is completely different. What promoted the development of human history? What made mankind start a new way of life? I said, this is science and technology. It is the development of science and technology that promotes the progress of mankind, and it is the development of science and technology that makes mankind have this brand-new and beautiful life. Throughout the ages, which 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 at it; Look at Zhaozhou Arch Bridge, with exquisite design; A glimpse of Compendium of Materia Medica, an oriental masterpiece; Look at the value of pi, seven decimal places; Overlooking the Silk Road and developing the economy; Blue-and-white porcelain is famous overseas. The development of science and technology is the road to a strong country, and it is the first driving force for the progress of the Chinese nation. Without science, how could we have a happy life today? Without science and technology, how can we have a comfortable material life and spiritual enjoyment? Without the progress of science and technology, how can we eat hybrid 2? How can we put on cotton clothes and live in tall buildings? The opposing side argues that the world has undergone many amazing changes since mankind entered the 21st century. While people are delighted with the rapid development of science and technology, they have also experienced better uneasiness and even disasters. Besides 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 invasion of various viruses, the exhaust gas behind cars, The waste gas from factories and so on do nothing to harm our beautiful home. Why are our homes threatened, why are trees being cut down in large quantities and why the air is not fresh? All these are all the evidences brought by science and technology. Modern science and technology has brought us some comfort and convenience, but at the same time it has also brought extensive influence. 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. Moderator: Ok, please argue and state your own views in the next section: In ancient times, people were superstitious about ghosts and gods, and thought that people's life was determined by heaven, and life, 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 the patients die painfully. But now, through the development of science and technology, most incurable diseases have been successfully cured, and people don't have to worry about getting sick ......................... It's just the tip of the iceberg of the case that the development of science and technology has benefited mankind. The ancient people couldn't even think about it. Why do people talk about promoting the development of science and technology almost every day on TV and in newspapers, because the dream of flying for thousands of years is so round? Is the development of science and technology; What caused the convenience of communication? 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 should 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? Don't they have judgment? Who thinks that their deaths are worthless, and who thinks that their dedication to science is meaningless at all? Opposing argument: 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 science and technology outweigh the benefits. First, although cars facilitate our travel, the exhaust from archways causes environmental pollution and affects human health. Second, the appearance of entertainment facilities such as television has brought convenience to people, but it has invisibly blocked the communication between people, which is weak. There is also the appearance of the network. It is undeniable that some lawless elements have an opportunity to disrupt people's lives and wait for a series of side effects brought by your so-called high technology. How can we sit idly by? Moderator: Well, both sides have stated their views just now, so we will enter the free debate session. Each side has 3 minutes, so please cherish it! There is a debate on the three sides: the development of science and technology has certainly 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 human beings can consciously reuse plastic bags instead of littering them at will, 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 discharge sewage illegally, will it cause serious water shortage now? There are still many such things going on, and some people not only don't reflect on themselves, but blindly point the blame at "science and technology". I feel ridiculous and hopeless for these people. Three arguments against the other side: what the other debater just said is just a hypothesis. Please come back to reality. If there is no obstruction from science and technology, why do you need to make such great efforts to publicize and protect the environment 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 network 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 China people's dream of flying for a hundred years, and the completion of the Bird's Nest Water Cube has fulfilled China's Olympic dream. Without science and technology, China can't be asked.
3. About the advantages of scientific and technological development outweigh the disadvantages, be brief.
It is true that science and technology have changed history. Without scientific and technological development, our life is unimaginable. Our life is dark. It is scientific and technological development that has saved us, and it is science that has saved us from the hot water age. We should respect him with a heart of awe. How can we say that the development of science and technology is full of drawbacks?
technology changes history, and knowledge changes destiny. We have entered the 21st century and an era full of high technology. Science has changed our lives, and science has changed our destiny. "Knowledge is power". How can we, the Chinese people, a vast country with a population of 1.3 billion, stand tall in front of the world? Because our technology is constantly developing! Our technology is constantly improving!
the advantages of scientific and technological development outweigh the disadvantages, which is an eternal theme!
4. Testimony that the advantages of scientific and technological development outweigh the disadvantages
How many amazing changes have taken place in the world since mankind entered the 21st century. 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 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. It is a new frontier discipline that studies the impact of various biological factors on human health and applies existing theoretical knowledge, technology, engineering design and equipment to prevent people engaged in related work, laboratories and the environment from being harmed by potentially infectious substances and biological toxic substances. Biosafety problems are at least manifested in the following aspects:
Great harm of infectious diseases
Infectious diseases include human, animal and plant infectious diseases, especially human infectious diseases are the most important biosafety problems, and infectious diseases are still the first cause of death in the world. In China, infectious diseases still seriously threaten 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 or erupting in some parts of the country and some countries and regions in the world every year
The potential threat of biological weapons and bioterrorism
In the 2th century, the whole international community made unremitting efforts to ban biological weapons and made some progress. However, in the 21st century, the potential threat of biological weapons has greatly increased, and some countries and regions may continue to research and develop biological weapons. In addition, the rapid development of biotechnology has greatly increased the potential threat of biological weapons, and the bioterrorism marked by the "anthrax incident" in the United States has posed a real threat to international security. Yuan Guoyong, 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, and the characteristic of this virus is that it is easy to recombine with other virus genes and then 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, and this virus is prone to mutation and extremely dangerous. Therefore, Yuan Guoyong believes that SARS virus has great potential to become the pathogen of making chemical and biological weapons except smallpox.
negative effects of biotechnology
the negative effects of biotechnology are mainly manifested as follows: first, when people develop and utilize biotechnology, unexpected security 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.
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 damage to national interests. The environmental release of genetically modified organisms poses a great threat to biodiversity.
Safety hazards of microbiology laboratory
Compared with other physical and chemical laboratories or other laboratories, microbiology and biomedical laboratory is a special laboratory, and 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 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.
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.
With the development of economy, the accelerated pace of people's life 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 the plastic waste in the garbage of cities, major traffic routes and tourist attractions increased 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%, with an annual growth rate of
48%. The plastic content of garbage in coastal cities is higher, reaching 8-1%. The waste
plastics account for more than one-third of the garbage by volume, which greatly increases the difficulty and cost of
garbage disposal.
