The benefits of science and technology to the environment

It can improve the environment, for example, scientific irrigation can prevent the salinization of land in North China.

Using scientific farming can prevent soil erosion.

Scientific development can promote the development of new energy and reduce air pollution.

Technology-A Double-edged Sword

Of course, there are too few technological achievements in the transformation of scientific knowledge, and we can only do evil. Most of them can not only benefit society, but also harm society and harm others and themselves. Therefore, "double-edged sword" is their most accurate metaphor.

Using scientific inventions to dominate the world is an example of a "double-edged sword". Verne was the first person to describe a scientific madman. In "Lord of the World", he described a madman Robil hiding in the crater. He invented amphibious vehicles as a hegemonic means. However, Verne is a loyal elder, and it is always inappropriate to write bad people. The image of "world master Robert" is also very funny.

In Wells' Invisible Man, Griffin became furious after he became invisible and called himself "Invisible Man I". However, he didn't even rule a remote English village, so he was rounded up by the villagers as a monster and died.

In The Great Dictator, the former Soviet writer Beliaev created a typical image of a scientific madman. German psychologist Steiner studied the information transmission between animals for a long time, and finally invented a device that directly controls other people's thinking with brainwaves. He left the scientific community and joined the financier gottlieb. First, he controlled gottlieb and his main assistant, then his business rivals, and even created stock market turmoil for his profits. Finally, Steiner's plot was discovered. He used this weapon to confront the armies of several countries, leaving the attacking troops at a loss and fleeing in panic. Steiner's plot failed only when his Soviet counterparts attacked him with the same weapon. Soviet scientists have transformed the instrument that controls others' thinking into a tool for the benefit of mankind: it has greatly accelerated the information transmission between human individuals, coordinated collective labor, and even made a band no longer have a conductor.

Zhao Nanyuan once said: The disasters and calamities caused by moral lunatics and religious lunatics are endless in history, and also abound in reality. Science madman only appears in Hollywood science fiction horror movies. Therefore, in recent years, the people who use science to do evil in science fiction writers' works are no longer the lunatics who always want to control the world. These villains want to achieve some more specific, less influential but more realistic goals through the new technology at hand.

Robin cook is good at "medical horror novels". Death Hormone is one of his sci-fi medical horror novels. Death hormone is an inherent hormone in human body, which is secreted by pituitary gland like growth hormone, but it will only appear after the secretion of sex hormones stops. Doctor Hayes was inspired by Pacific salmon, which died immediately after spawning. Hayes finally extracted the inducer of death hormone from salmon head. When injected into an organism, death hormone can be released immediately in large quantities.

Hayes works in a large membership health care center. Some successful middle-aged people join this health care center in order to get lifelong health care treatment. However, for some time, there have always been some middle-aged people who died suddenly. They all have bad habits of smoking and drinking, but their experiences before entering the health care center show that their physical condition is still normal. When they die, their cardiovascular system is extremely aging. Hayes himself was finally included in this death list. These seemingly normal deaths aroused the suspicion of Dr. Jason. After repeated investigations, he finally found out that Shirley and others in the health care center secretly gave these people the death hormone inducer extracted by Hayes, so that they would die early, so as to avoid being forced to provide a large number of free drugs after aging.

At the end of the novel, several characters in the book directly discuss the good and evil of science and technology on the issue of death hormone, and whether it is necessary to set up laws to restrain scientists from inventing at will. This shows that the author has a conscious understanding of the good and evil of science when creating.

/kloc-at the end of 0/9 century, skyscrapers were born in the United States, which soon became a symbol of the combination of technology and wealth. In the second half of the 20th century, many countries and regions in East Asia joined the competition of skyscrapers, and the speed at which high-rise buildings sprang up cannot be described as "mushrooming". And the high cost burden and disaster hidden danger brought by skyscrapers have also become the focus of people's attention. The novel "The Burning Skyscraper" takes this as its theme.

When the novel came out, the tallest building in the world was the Sears Tower in Chicago. In the story, the author fictionalizes the new first floor of the world, which is located opposite the Sears Tower, so that at the end of the novel, the rescue team can set up a steel rope between the Sears Tower and the "first floor of the world" to save people. The boss on the first floor of the world cut corners in order to catch up with the construction period, which led to excessive circuit load and a dark fire on the opening day. The unique "stack effect" of skyscrapers makes the dark fire go up layer by layer until the top floor. There, hundreds of dignitaries are holding a celebration ceremony. Due to safety negligence and other reasons, when people find a fire, it can't be put out.

The concern about the fire hazard of skyscrapers is expressed through the mouth of the fire chief. After the fire broke out, the fire chief came to the scene, met the architect and asked the latter, "You know that fire fighting technology can't do anything for fires over seven floors. Why do you want to build such a high building?" Finally, he said something even more horrible: Today was not bad, only 200 people died. In the future, similar fires will cause thousands of deaths. Only in this way will you know what kind of building you should build! The film was shot in the 1980s, and ten years later, this terrible prediction came to the Twin Towers of the World Trade Center. In the 9 1 1 attack, the casualties of the Pentagon were far less than those of the World Trade Center. 9 1 1 attack If there were no "cheers" from tall buildings, it might just be an enlarged Lockerbie air crash.

This novel was later adapted into a film, with a large number of celebrities participating in it, which was quite influential. Only at the end of the novel, many people, including the governor, did not escape from the fire. The film added a brighter ending: rescuers blew up the water tank on the roof and put out the fire. But that's not reality. The water in the water tower on the roof is really a drop in the bucket for the raging flame like the 9 1 1 incident.

1972, mankind crossed the threshold of transgenic technology in Stanford University. It releases an almost infinite possibility: according to human needs, the genes of different species are mixed together to create new species that are not found in nature. As soon as gene technology was born, it was immediately applied to agricultural science and technology, creating a large number of new species. While providing high-yield crops, they also created a big storm against accepting and resisting genetically modified crops. Not long ago, a storm that farmers destroyed genetically modified experimental fields in Wuhan showed that this wave of resistance has now blown to China. The short science fiction "Doing Good for Heaven" is set in genetically modified crops.

In this novel, American MSD Biological Company invested 2 billion dollars to successfully cultivate "devil strain" wheat. It has high yield, disease resistance and good quality. In order to prevent farmers from storing the harvested wheat, MSD company mixed the toxic protein gene that caused infertility into the gene of devil wheat. In this way, the second generation of wheat seeds would not grow without the special solvent that the company secretly mastered to inhibit the toxic protein gene. This is understandable for the means of protecting intellectual property rights. A junior employee of MSD Company is responsible for marketing it to Shaanxi, China. In the first year, the harvest was excellent. In the second year, some farmers secretly stored seeds, resulting in the loss of large areas of wheat fields. Although MSD has done a lot of preventive research, this suicide gene has spread to other wheat varieties because of the carrying function of some special viruses. Black dead wheat spread like a plague.

In the "bad science" works about grain, immortal grain is also a very interesting example. Blay, a scientist in Beliaev, is not only harmless, but also has no commercial purpose like MSD. He cultivated a single-celled organism, which can directly obtain nutrition from the air, expand itself, can be eaten directly, and become an "eternal food". However, this "eternal food" not only failed to solve the hunger problem, but also led to the bankruptcy of farmers and aggravated the economic crisis. Finally, with the arrival of summer, the appropriate temperature makes the "eternal grain" multiply rapidly, covering one piece of land after another, becoming a man-made disaster.

Network technology has spread to the whole world with the trend of blowout since it appeared in 1970s. Among the people I know, no one who has been online will choose not to contact the internet from now on. It has become the work and life style of many people. But the internet has also made many people addicted and become its prisoners. Nowadays, the problem of Internet addiction has become a new educational problem. According to the author's observation, adults have a large number of Internet addiction patients, but they are independent and responsible, unlike teenagers who have guardians to reflect this problem to public opinion.

In the short science fiction novel Pink-purple Dandelion, Xinghe describes a future world where Internet addiction is widespread. In this era not far from now, Internet addiction has become a serious social problem, and even requires compulsory withdrawal. Like today's drug rehabilitation centers, the judicial system has also seen a net-free prison. The novel describes the reaction of internet addicts: they are upside down day and night, unable to work, difficult to communicate with others, stubbornly looking for internet tools everywhere, and even using prison riots to resist compulsive addiction. And because the author uses the first person, from the perspective of an internet addict, this story shows the harm of internet addiction. The serious physiological reaction described in the novel has already existed in some Internet addiction patients.

The author also conceives the specific measures of compulsory abstinence from Internet addiction in the future: First, it is mandatory to let addicts basically leave the network, which is backed by law. Of course, in order not to have a nervous breakdown, they will surf the Internet with restrictions under supervision. Then force addicts to participate in high-intensity activities. A person who has been sitting in front of a computer for many years is in rather bad health. In addition, addicts are forced to read printed books and gradually get rid of their dependence on computers.

1928, an accidental phenomenon in the laboratory, coupled with the prepared mind of British medical scientist Fleming, helped mankind enter the era of antibiotics. Nowadays, antibiotics have become a common weapon for doctors. However, the abuse of antibiotics leads to the increase of bacterial drug resistance, which also forms new medical problems. The novel Life and Death Balance describes this theme. Although the author Wang Jinkang has long been a minor celebrity in the sci-fi circle, he can attract public attention outside the sci-fi circle, largely because of this novel, because it involves a thorny issue at the forefront of science and technology today.

Set in the Middle East, the novel describes the story of a military madman launching a germ war against neighboring countries. A parallel clue is the Huangfu family's research on "balanced medicine". As a fictional element in the novel, balanced medicine itself is not important. It is important that the author tells his concern about antibiotic abuse through this element. Through the mouth of the medical madman Huangfu Youshan, the author wrote: "Drug-resistant strains have developed like floods, even common bacteria such as Escherichia coli and Shigella dysenteriae have drug-resistant strains, and antibiotics can do nothing. The amount of penicillin used to treat sepsis has increased from tens of thousands of units to tens of millions of units, but the mortality rate has still risen to the level before the emergence of antibiotics. " Science fiction world, 97, 5, 15.

The author even invented a case of renal failure. This is a member of Gao Qian's family. It is because of her position that she can use a lot of new drugs and good drugs, and has been caught in the trap of abusing antibiotics for more than 20 years. The author used a long medical record to describe how she gradually recovered from a minor illness and was finally surrounded by drugs.

■ Fang: While human beings are singing a song of triumph for science and technology, please don't forget that science and technology can also give evil spirits demonic power.

The destruction of mankind by science and technology is also based on the all-round distortion of human development by modern science and technology, which is concentrated in three aspects: social relations, spiritual field and ethics.

On the contrary: technology is the strongest shield to protect mankind. We believe that the continuous progress of technology will surely bring mankind into a more beautiful and mysterious realm.

Mankind will not be destroyed by science and technology, because the development of science and technology has proved that the magic height is one foot and the Tao height is ten feet. The problems brought by science and technology to mankind can be solved through the further development of science and technology itself.

Wu Tian (positive statement): First of all, everything has two sides. I don't need to waste my breath on the benefits of technology. Later, other debaters will talk a lot. However, we often think that what is diluted or even ignored is its negative impact. 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. However, if you think that human beings have clearly realized the existence of double-edged swords, then you are somewhat naive. When humans proudly say time and time again that new technologies are being applied at the fastest speed, which shows how efficient we are, have you ever thought that it also means that it is too late to understand the negative effects of technology, or you don't want to know at all? The destruction of science and technology reflects an irreversible trend, which is the beginning of disaster.

Second, the uncertainty of the development of modern science and technology makes the double-edged sword of science and technology become the sword of Damocles. Humans have long been impatient with the use of science and technology. After years of accumulation, the negative effects of science and technology break out on a global scale at any time, which is a deeper crisis of the destructive trend of science and technology.

Third, the high dependence on science and technology makes the sword of Damocles ready 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.

Kevin·Z (Objection): First of all, we should point out that the negative effects of science and technology cannot be attributed to science and technology. On the contrary, it is the evil result of mankind's failure to scientifically understand the world as a whole and unreasonable use of science and technology.

Second, the debater overestimated the difficulties brought by science and technology, but underestimated the ability of human beings to solve these difficulties. Scientific and technological problems that cannot be solved at present do not mean that they cannot be solved in the future. We believe that mankind will not be destroyed by science and technology, because the course of scientific and technological development has proved that the magic height is one foot and the Tao height is one foot, and the problems brought by science and technology to mankind can be solved through the further development of science and technology itself. In 1970s, scientists predicted that mankind would face an energy crisis at the beginning of 2 1 century due to the excessive consumption of natural resources by scientific and technological products. Now with the development of energy and micro solar energy, this panic has disappeared.

Third, science and technology are in the hands of human beings, who can create a scientific prevention system through ethics and legal norms, so that the negative effects brought by individual technological inventions can be restricted in the whole system.

Jane (debating): Another debater said that human beings have moral laws, but can moral laws control technology? Scientists copy people on the high seas, which is beyond the control of moral law. We believe that mankind will be destroyed by science and technology, and it is also based on the all-round distortion of human development by modern science and technology, which is concentrated in three aspects: social relations, spiritual field and ethics. First of all, the development trend of science and technology may destroy human social life. Secondly, the destructive power of science and technology is also reflected in its constant impact and destruction on human life, which is concentrated in the Internet and gene technology, the two new favorites of human science and technology. The warriors of the Internet have long announced that they want to turn the Internet into a kind of life. However, when the virtual replaces the real, people's existence as a society disappears. As the saying goes, skin does not exist, how can hair be attached? Look at gene technology, life technology cures diseases, but on the other hand, it interferes with nature and creates a more perfect human being. But is the perfect genetically modified person human or a high-tech product? Today, the change of gene technology to human nature directly impacts the last line of defense of human spiritual home-ethics. The all-round distortion of human society by science and technology is destroying our social foundation and spiritual world.

First of all, science and technology are the driving force of human progress.

Secondly, without science and technology, human beings would have died long ago. Science and technology are the strongest shields to protect mankind. We believe that the continuous progress of science and technology will bring mankind into a more beautiful and mysterious realm, so we believe that mankind will not be destroyed by 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?

■

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!
