First of all, the biggest disadvantage of technological development is that it makes our personal safety less and less secure. In World War II, in order to force Japan to surrender quickly, the U.S. dropped a uranium bomb, code-named "Little Boy," on Hiroshima at 8:15 p.m. on Aug. 6, 1945, killing and injuring 200,000 of the city's 245,000 people and reducing the entire city to rubble.
At 11:02 a.m. on Aug. 9, 1945, following the attack on Hiroshima, the U.S. military carried out a second atomic bomb attack on Japan, targeting Nagasaki. The bombing resulted in more than 100,000 same-day casualties and missing persons out of Nagasaki's population of 230,000, and the destruction of 60 percent of the city's buildings.
The legacy of the atomic bombings of Hiroshima and Nagasaki is still being felt today, with survivors suffering from the after-effects of radiation such as cancer, leukemia and skin burns. As of August 2007, according to Japanese authorities, more than 250,000 people had died in Hiroshima and 140,000 in Nagasaki as a result of the atomic bombings. The development of nuclear weapons led to a quantum leap in science and technology. But now, because of nuclear weapons, many people have lost their lives and families.
It is not unique. Scientific and technological development brings disadvantages two: with the development of scientific and technological level and the improvement of people's living standards, environmental pollution is also increasing, especially in developing countries, environmental pollution is increasingly becoming one of the world's countries **** the same subject. Due to the people of the highly developed industry of the negative impact of insufficient anticipation and prevention of unfavorable, resulting in a global three major crises: resource shortages, environmental pollution, ecological damage.
......
Consolidating the above, the disadvantages of scientific and technological development have y hurt us human beings and broken the stable development of society. Therefore, we believe that the disadvantages of scientific and technological development outweigh the advantages.
1The development of atomic physics theory is that mankind has mastered the nuclear energy technology, but also brought the nuclear disaster in Hiroshima, brought mankind fifty years of "horrible peace", mankind for the first time has the ability to destroy itself. In addition to the numerous nuclear accidents, most notably the Chernobyl disaster in the Soviet Union (please search the internet for specific data), the development of chemistry has given us the unprecedented ability to modify nature, but our gunpowder and explosives have also harmed tens of millions of our fellow human beings. Our chemical synthesis technology has allowed us to create things that did not exist in nature, but now we are also plagued by white trash, poisoned by chemical pollution, and why so many children in our country are now suffering from leukemia, a very important factor is the use of chemical binders in home renovation, as well as ozone-destroying Freon. The development of oil exploration technology is the pace of human progress is greatly accelerated we have been able to fly faster than the speed of sound, but this also brought too many wars too much trouble, but also make the earth began to cold fever. The development of biotechnology has given us the power to create life, which was previously monopolized by God, but it has also brought about ethical disorders. In short, scientific progress has always been accompanied by the danger of corresponding drawbacks, and today we must face up to these negative impacts or we may end up destroying the human race at our own hands.
2Personal safety is becoming increasingly insecure. Nowadays there are tens of thousands of crimes occurring on average every day. Most of these crimes are committed by means of new technology. Gun crime, in particular, has become a major concern for the general public. And as we saw in World War II, with the advancement of technology, wars now cause far more damage and loss than ever before. It may even lead to the end of the human race.
3The quality of human body is not as good as before. With the development of science and technology, gas cars, trains, airplanes and other means of transportation to make the human daily life has undergone a major change, human beings are no longer always rely on their own legs, and therefore the physical quality of human beings and the previous compared to the physical quality of human beings has been incomparable. In the past, Xiang Yu's "power to pull mountains and rivers to cover the Ruoxi" is no longer possible in today's society. And this situation continues to develop is likely to make the human limbs atrophy, so that human beings appear a new form.
4 A variety of emerging germs continue to appear, many of which have far exceeded the destructive power of the previous germs. This is due to the rapid development of medical technology to accelerate the mutation of viruses. So much so, that technology is no longer able to keep up with the speed of virus mutation. Perhaps one day the human race will be destroyed by a major plague.
5 the people's pace of life and improve the standard of living, the amount of plastic Increasing day by day. 1996, China's plastic packaging usage amounted to 2.43 million tons, an average annual growth rate of more than 20%, especially in the city, the main transportation routes, tourist attractions in the garbage in the rapid increase in plastic waste. According to the survey, Beijing's annual output of domestic garbage has reached 3 million tons, of which waste plastics accounted for about 3%, with an annual growth rate of 48%. The plastic content in the garbage of cities in coastal areas is even higher, amounting to 8-10%. These waste
Plastic in the proportion of garbage by volume, has reached more than one-third, and greatly increased the difficulty and cost of garbage disposal. Due to the waste plastic hundreds of years are difficult to degrade, if discarded in the natural environment, will give mosquitoes, flies and bacteria to provide a breeding ground; if buried in the ground, it is easy to contaminate the groundwater, hindering the growth of plant roots, destroying the quality of the soil, affecting the crop harvest; if the fire incineration treatment, will produce a variety of toxic gases. "White pollution" has become a major environmental hazard in our society, seriously hindering the sustainable development of our economy and environment.
6The development of science and technology is based on the premise of destruction, based on the continuous summary. So his development and further deepening will certainly bring a certain degree of negative impact on the environment. In view of the long and slow history, this destruction will be more serious with the development of technology!
7Today's society, the automobile is everywhere, not only to the human body and mind caused great harm, but also caused the pollution of the atmosphere. All creatures in the world have been victimized by this "technological product" to a certain extent, and it is selfish for human beings to disregard the safety of other creatures on earth for their own convenience. On the other hand, automobiles are also very harmful to human beings. Freon in air conditioners and refrigerators is destroying our precious atmosphere. The so-called high-tech products have made the world dirty and rigid, and the free earth has been swallowed up by human beings, the free sky has been shrunken by human beings, and the free sea has been encroached upon by human beings.
8At present, with the rapid development of biotechnology, the issue of biosafety has become a big proposition affecting the whole country, the whole world politics, economy, security and peace. In recent years, especially after the "anthrax infection" in the United States, biosafety issues have attracted much attention both at home and abroad, and biosafety terminology is often found in documents of governmental or nongovernmental organizations, and in all kinds of media. The global pandemic of SARS will undoubtedly make countries all over the world pay more attention to biosafety issues and take it as an integral part of national security. The global SARS epidemic will undoubtedly make countries around the world pay more attention to biosecurity and make it an integral part of national security.
9Microbiological and biomedical laboratories are special laboratories compared with other physical and chemical laboratories or other types of laboratories, in which everyone who works in them, and the surrounding environment with which they come into contact, is at high risk of contracting infectious diseases or health effects. Negligence and accidents in the management of microbiological laboratories can lead not only to infections among laboratory workers, but also to environmental contamination and widespread infections in the population. Accidental infections in laboratories at home and abroad are not uncommon, and in serious cases, thousands of laboratory animals have had to be slaughtered, even leading to the death of laboratory workers.
10People in the development and utilization of biotechnology, there may be unexpected safety problems. For example, there is now widespread concern about the harm to biodiversity posed by the environmental release of various types of genetically modified organisms (GMOs). Similar problems may also exist with genetically engineered drugs, vaccines, genetically modified foods and gene therapy. Misuse of biotechnology and unethical application of biotechnology may also pose significant safety risks. The research on human cloning is a prominent example.
So, technology has changed history, and there is no need to question whether the benefits or harms of technological development are greater, because they are! The benefits are great! The benefits are great! You say that the development of science and technology has brought about atmospheric pollution, you say that the development of science and technology has produced white trash, you say that the development of science and technology has formed a warming of the temperature ...... All things can not be perfect, the brighter the place behind the shadows of the darker, but on the basis of these you determine that the development of science and technology has done more harm than good? "The world is different things are different" times are different, the problems encountered are different, say air pollution, provinces and cities have launched a preventive plan; white trash, unified treatment; automobile exhaust caused by warming scientists have developed a solar-powered cars. Look at now, solar water heaters, solar air conditioning, solar batteries ...... environmentally friendly and economical solar energy has been gradually into thousands of households, this is not technology in development?
While there are drawbacks, but compared to the benefit of mankind, environmental protection home of the concept of scientific and technological development, irrelevant, as long as there are drawbacks, scientists will find ways to solve the same, we can not choke on food, the pace of scientific and technological development will not stop for a moment. There is no denying that technological development is the only answer to the question of whether it is beneficial or not! Because technology has been progressing, science has been developing, cunning sophistry, generalized words, unreasonable nonsense can not change this truth. If you say that technology has done more harm than good, can you go a week without taking the bus to class, without using a neutral pen, without using a ballpoint pen, without using a fountain pen? Can you go a week without watching TV, listening to the news, reading newspapers, reading books, or surfing the Internet? Can you go a week without eating the hybrid rice you developed? No pasta? No drinks? You can't, you can't, you can't, because technology has been closely related to you, has been inseparable from you! In the question, if you write a letter to the President, saying that the proposal to stop all scientific research activities, everyone is to give you flowers, or that board special pat you?
Technology changes history, good, no scientific and technological development, our life is unimaginable, our days are dark, is the development of science and technology to save us, is the science of our rescue from the age of hot water. We should respect him with a heart of reverence, how can we say that the development of science and technology is full of shortcomings?
Technology changes history, knowledge changes destiny. We have entered the 21st century, into a high-tech era. Science has changed our lives, science has changed our destiny. "Knowledge is power", our Chinese people **** and the country, 1.3 billion people in a great country, why can the world in front of the chest up? Because our technology is constantly developing! Our technology is constantly progressing!
The benefits of technological development outweighs the disadvantages, which is an unchanging theme!
The advantages and disadvantages of the development of science and technology
Conclusion: the development of science and technology is important, but not in a reasonable and normal use of the premise of the development, the development of first of all must be purified thought, only no personal thought and the mind to get the development and improve the development of high-tech can be developed to permanently benefit the development of mankind, the harmony of nature!
Drawbacks: the above said that each of us look higher and farther away, which makes us see is just far away from the high things, to explore to pursue, ignoring the immediate do, like those in history who want to find the long life of a number of monarchs, drugs are used to treat the disease, the results of their blind investment in order to achieve some of the impossible to achieve something, the results of the harm to themselves and to the people, the result is that they can not be achieved, but also to the people. The result is to harm themselves and the people, there are people now in the movie to see the macro scene, let a person's heart chills the emperor burial and those so-called miracles of the world.
The development of science and technology has brought both convenience and disaster.
We can go wherever we want, people are constantly exploring, and in the future even the "Solar Center" will be overturned. With the advancement of technology, no one can enjoy the things that the historical figures did not, each newcomer has a different understanding of the world, and we are looking farther ahead!
Let's compare today's life with that of 100,000 years ago, we are supreme; compare today with that of thousands of years ago, we are superior; compare today with that of hundreds of years ago, we are happy and comfortable; compare today with that of tomorrow, the future is bright and beautiful. Thousands of years, from the horse-drawn carriage into cars, trains, airplanes; from kerosene lamps into incandescent lamps, neon lamps, energy-saving lamps; from the ends of the earth into the near at hand, video chatting, the mouse a little bit to know the world. This is the power of science and technology!
So, technology has changed history, we explore the development of science and technology is a big advantage or disadvantage is no need to question, because it is a big advantage! The benefits are great! The benefits are great! You say that the development of science and technology has brought about atmospheric pollution, you say that the development of science and technology has produced white trash, you say that the development of science and technology has formed a warming of the temperature ...... All things can not be perfect, the brighter the place behind the shadows of the darker, but on the basis of these you determine that the development of science and technology has done more harm than good? "The world is different things are different" times are different, the problems encountered are different, say air pollution, provinces and cities have launched a preventive plan; white trash, unified treatment; automobile exhaust caused by warming scientists have developed a solar-powered cars. Look at now, solar water heaters, solar air conditioning, solar batteries ...... environmentally friendly and economical solar energy has gradually entered thousands of households, this is not technology in development?
Technological development, there is no excuse, is the benefit of the big, the only answer to this question! Because technology has been progressing, science has been developing, cunning sophistry, generalized words, irrational nonsense can not change this truth. If you say that technology has done more harm than good, can you go a week without taking the bus to class, without using a neutral pen, without using a ballpoint pen, without using a fountain pen? Can you go a week without watching TV, listening to the news, reading newspapers, reading books, or surfing the Internet? Can you go a week without eating the hybrid rice you developed? No pasta? No drinks? You can't, you can't, you can't, you can't, because science and technology have been closely related to you, have been inseparable from you!
May 12, 2008 14:28, I believe we must not be unfamiliar with this time. It was then that a massive earthquake measuring 8.0 on the Richter scale struck Wenchuan County, Sichuan Province, and the story behind it is well known. But think about it, what brought the liberators and soldiers to the disaster area by water? What sent the relief supplies to the disaster area by air drop? What opened the highway to Wenchuan in the first time? What helped people saw through the steel bars to dig out the injured? What helped the doctors bring back the injured from the death line? --It's assault boats, helicopters, excavators, chainsaws and medical equipment. That's the power of technology! We should continue to develop technology and build earthquake-resistant houses so that more people can be spared. This natural disaster reinforces our view that the development of science and technology is beneficial in the future.
Darwin once said, "Survival of the fittest is the law of nature." The panda's ability to reproduce is weaker than that of other animals, and the fact that it is so picky about what it eats and how it lives alone has put it on the brink of extinction. Look at the cockroaches, even if the atomic bomb exploded, the cockroaches there are still "running for prosperity"? Besides, science can help pandas by healing their wounds and delivering babies. How wonderful!
With the development of science and technology, human civilization has taken a big step forward, from the former horse-drawn carriages to automobiles, from the former oil lamps to electric lamps ......
Now, people's lives have changed for the better. With the telephone to speed up communication, with cars, motorcycles to speed up the pace of life, with electric cookers, gas to make delicious meals ......
Television is indispensable in life. We can watch the news, to understand the domestic and foreign affairs; can watch cartoons, relax; also can not go to the scene to see the program, performance; for example, this Olympic Games mascot was unveiled, you can watch the broadcast at home.
Computers are more widely used in all walks of life, we send a letter to Brazil in Haining, as long as the other party can receive in a few seconds. We can chat on the Internet and friends and family from all over the world, games; you can read the news online, watch movies, listen to music; you can listen to the teacher's classes, find information, but also can not leave the house shopping, medical care, first aid ......
We can say that, science and technology and we are closely related. With this developed technology, our life is faster and more convenient, colorful.
We can go where we want to go, people are constantly exploring, in the future may even back to the "solar center" will be overturned. With the advancement of technology, no one can enjoy the things that the historical figures did not enjoy, and every newcomer to the world has a different understanding of the world, and we look farther ahead!
