The disadvantages brought by the disadvantages of developing low-carbon science and technology ~ be specific ~ it is best to have examples.

1. Humans rely on scientific achievements without thinking,

making their brains waste,

becoming lazy,

reducing the labor force,

most people are on the verge of being laid off.

1. Environmental pollution. This is the most direct and conspicuous disadvantage.

2. The accelerated extinction of species. This is the

disadvantage of scientific and technological development caused by environmental pollution and human hunting.

3. Personal safety is increasingly insecure. Now there are tens of thousands of criminal acts every day on average. Most of their criminal means are related to current new technologies, especially firearms. It is even more difficult for ordinary people 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 being comparable before and may even lead to the fate of human extinction.

4. The physical quality of human beings is not as good as before. With the development of science and technology, the emergence of various means of transportation such as gas cars, trains and airplanes has greatly changed human daily life. Human beings are no longer always dependent on their own legs, so the physical quality of human beings can't be compared with that of the past. In the past, Xiang Yu's "pulling the mountains and rivers to cover the air" is impossible to appear in today's society. If this situation continues to develop, it may make people's limbs shrink and make human beings

appear a new form.

5. Various emerging germs continue to appear. 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 variation of viruses, so that the development speed of science and technology has failed to keep up with the variation speed of viruses. Perhaps one day mankind will die of a major plague.

2. Environmental pollution is the most direct and conspicuous disadvantage. People always think that the sea, land and air on the earth are endless, so they never worry about sending millions of tons of waste gas into the sky. Everyone thinks that the world is so big, what is this waste? We are wrong. In fact, although the earth is large (with a radius of more than 6,3 kilometers), creatures can only live in the range of 8 kilometers above sea level to 11 kilometers under the sea, and 95% of the creatures can only live in the range of about 3 kilometers in the middle. People have wantonly polluted this limited living environment in three ways. Marine pollution: mainly crude oil leaked from oil tankers and oil wells, pesticides and fertilizers used in farmland, sewage discharged from factories and acidic solutions from mines; They pollute most marine lakes. As a result, not only marine organisms are harmed, but also birds and humans may be poisoned by eating these organisms. Land pollution: garbage cleaning has become an important problem in major cities. Many of the tens of millions of tons of garbage every day cannot be incinerated or decomposed, such as plastic, rubber, glass, aluminum and other wastes, which have become the number one enemy of urban sanitation. Air pollution: this is the most direct and serious, mainly from carbon monoxide and hydrogen sulfide released by factories, automobiles, power plants, etc. Every day, people get sick of respiratory organs or visual organs because of contact with these dirty air. If we still ignore the experts' warnings, we will definitely fall to the point where there is no half an inch of pure land to live in in the future. The extinction of species is accelerating. This is caused by environmental pollution and human hunting. It also belongs to the disadvantages of scientific and technological development. Personal safety is becoming more and more insecure. Now tens of thousands of crimes occur every day on average. Most of their criminal means are related to the current new technology. Especially gun crimes are hard for ordinary people 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. In 1996, the consumption of plastic packaging in China reached 2.43 million tons, with an average annual growth rate of more than < P > 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.

Because waste plastics are difficult to degrade for hundreds of years, if discarded in the natural environment, it will provide a breeding ground for mosquitoes, flies and

bacteria. If buried underground, it will easily pollute groundwater, hinder the growth of plant root system, destroy soil quality and affect crop harvest; If it is incinerated by fire, a variety of poisonous gases < P > will be produced. "White pollution" has become a major public hazard that harms China's social environment and seriously hinders the sustainable development of China's economy and environment.

1. The development of atomic physics theory has enabled mankind to master the nuclear energy technology, but it has also brought about the nuclear disasters in Hiroshima and Changqi, and brought about the "terrible peace" of mankind for 5 years. For the first time, mankind has the ability to destroy itself. In addition, there are endless nuclear accidents, among which Chernobyl in the Soviet Union is the most famous (please search online for specific data). The development of chemistry has enabled us to gain unprecedented ability to transform nature, but our gunpowder and explosives have also hurt tens of millions of human compatriots. Our chemical synthesis technology has created things that do not exist in nature, but now we are also troubled by white garbage and poisoned by chemical pollution. Why do so many children in our country suffer from leukemia now? The very important factors are the chemical binders used in home decoration and Freon that destroys the ozone layer. The development of oil exploration technology has greatly accelerated the pace of human progress. We have been able to fly at a speed exceeding the speed of sound, but it has also brought too many wars and too many disturbances, and the earth has begun to catch a cold and have a fever. The development of biotechnology gives us the power to create life which was monopolized by God before, but it also brings ethical disorder. In a word, the progress of science is always accompanied by corresponding disadvantages and dangers. Today, we must face up to these negative effects or we human beings may eventually be destroyed in our own hands.

2 Personal safety is becoming more and more insecure. Now, tens of thousands of crimes occur every day on average. Most of the criminal methods are related to the new technology. Especially, gun crimes are hard for ordinary people to guard against. From the Second World War, we can already see that with the development of science and technology, The damage and losses caused by the current war are far from comparable. It may even lead to the fate of human extinction.

3 The physical quality of human beings is far from what it used to be. With the development of science and technology, the emergence of various means of transportation such as gas cars, trains and airplanes has greatly changed human daily life, and human beings are no longer always dependent on their own legs. Therefore, the physical quality of human beings can't be compared with that of the past. In the past, Xiang Yu's "pulling the mountains and rivers to cover the air" is impossible to appear again in today's society. If this situation continues to develop, it may make people's limbs shrink and make human beings appear in a new form.

4 Various emerging germs appear constantly. 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 variation of viruses, so that the development speed of science and technology has failed to keep up with the variation speed of viruses. Perhaps one day mankind will perish from a major plague.

5 With the acceleration of people's living pace 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 in the garbage of cities, major traffic routes 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%, with an annual growth rate of 48%. The plastic content of garbage in coastal cities is higher, reaching 8-1%. The proportion of these waste

plastics in garbage has reached more than one third by volume, which greatly increases the difficulty and cost of garbage disposal. Because waste plastics are difficult to degrade for hundreds of years, if discarded in the natural environment, it will provide a hotbed for mosquitoes, flies and bacteria to survive and breed; If buried underground, it will easily pollute groundwater, hinder the growth of plant roots, destroy soil quality and affect crop harvest; If it is burned by fire, it will produce a variety of toxic gases. "White pollution" has become a major public hazard that harms China's social environment and seriously hinders the sustainable development of China's economy and environment.

6 the development of science and technology is based on destruction and continuous summary. Therefore, its development and further deepening will definitely bring some negative impacts on the environment. Looking at the long history, the damage will be more serious with the development of science and technology!

7 In today's society, cars can be seen everywhere, which not only does great harm to people's body and mind, but also pollutes the atmosphere. All the creatures in the world are infringed by this "scientific and technological product" to some extent. It is selfish for human beings to take care of the safety of other creatures on earth for their own convenience. To say the least, cars are also very harmful to human beings. Freon in air conditioners and refrigerators also destroys our precious atmosphere. The so-called high-tech products make the world dirty and rigid. The free land is swallowed up by human beings little by little, the free sky is shrunk by human beings little by little, and the free sea is occupied by human beings little by little.

8 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.

11 Like any industrial product 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 earth's ozone layer by refrigerants, but in recent years, due to the development of refrigerant renewal, this is no longer the main factor. The impact of air conditioning on nature in the future is still reflected in the field of energy consumption, which has accounted for a large proportion of the total energy consumption of our life and industry. The exploitation of energy and the release of a lot of heat to the atmospheric environment have caused a great burden to our natural environment, which is the major problem we have to solve for a long time.

12 the development of science and technology will bring countless industrial workshops. China was originally short of water, and the sewage and exhaust of industrial workshops will not be restored by normal natural restoration. By then, no one in China will have water. Besides, exhaust gas, sulfur dioxide and sulfur monoxide will do great damage to the environment, especially ozone. You still think the ozone hole is too small! ! ! ! ! ! ! ! !

in the 13th 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.

1, transgenic technology, although there is no data that it must be harmful to the body, but it is likely to be harmful!

2. Cloning technology. Dangerous technology.

3. Nuclear fusion and fission technology. Accidentally, the earth perished!

4. chemical technology. The culprit that makes men unable to stand up!

5. medical technology. It's the fault of China's boys and girls.

6. Space technology. Accidentally, the whole alien is extremely dangerous.
