Human beings have mastered nuclear energy technology, but it has also brought about the nuclear disasters in Hiroshima and Changqi, and brought about the "terrible peace" of human beings for 51 years. For the first time, human beings have the ability to destroy themselves. 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.

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.

Environmental pollution. This is the most direct and conspicuous disadvantage. 2. The extinction of species is accelerating. This is caused by environmental pollution and human hunting. It also belongs to the disadvantage of scientific and technological development. 3. Personal safety is increasingly insecure. Now there are tens of thousands of criminal acts every day on average. Most of its criminal means are related to the current new technology. Especially gun crimes, 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. It 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 air cars, trains, planes and other means of transportation 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 today can't be compared with that of the past. In the past, Xiang Yu's "pulling out the mountains and rivers" is impossible to appear again in today's society. If this situation continues to develop, it may shrink people's limbs and make human beings appear in 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 perish from a major plague.

With the development of science and technology, let's talk about oil! Oil was originally the painstaking efforts of the earth, so human beings have drained the painstaking efforts of the earth, which is the end. Oil is also used to lubricate the center of the earth. If there is less oil, there will be more earthquakes, just like machines.

When human beings entered the 21th century, how many amazing changes have taken place in the world. 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 invasion of all kinds of viruses, the exhaust gas behind cars, the exhaust gas from factories, etc. do not help to infringe on our beautiful home. Why is our home threatened, why are trees cut down in large numbers, and why the air is not fresh? All these are all kinds of criminal evidence brought by science and technology. Modern science and technology has brought us some comfort and convenience, but at the same time it has brought about 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.

The development of science and technology has brought benefits to our lives, which we don't deny. However, we think 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. Secondly, the appearance of entertainment facilities such as television has brought convenience to people. However, it invisibly blocks the communication between people, which is indifferent to human feelings. There is also the emergence of the internet, which gives some lawless elements an opportunity to disrupt people's lives and a series of side effects brought by your so-called high technology. It is undeniable. How can we sit idly by?

Although scientific development has made great progress in society and promoted the improvement of our living standards, it is precisely because we overemphasize development and neglect environmental problems. In the process of development, the damage to the environment caused by our pursuit of interests has made our home miserable, and the death of wild animals has caused him to be endangered or even extinct. Industrial wastewater has caused water pollution, resulting in a large reduction of potable water.

Industrial waste gas has caused air pollution, and the hole of ozone has caused the glaciers in the North and South poles to melt and the sea level to rise. This is all brought about by scientific development.

2. Scientific development makes us over-exploit the earth's energy, but those non-renewable resources are seriously lacking. At present, we are exploiting the resources of our descendants for decades or even hundreds of years. Then, when there is no new energy to provide, what will they use to live?

The development of science has brought the shadow of war. Every country wants its own country to be the most powerful, so for this purpose, they must develop those powerful scientific weapons. The research and development of these weapons first needs money. Where does the money come from? Of course, we have to bear this pressure, and the development of weapons needs experiments. Where to experiment? Some unmanned areas, so the experiments of weapons have caused serious damage to that area, so that the land can not be used. And the radiation it produces remains for a long time, then the land will be completely abandoned, which is a big waste for our society now.

4 when a country is strong, people will have ambitions. What will happen if they have ambitions? Of course, they will wage war, although there are not many people in the war now, just a few missiles. But it is these missiles that can cause a country or a region's economy to fall back for decades, and how much financial resources are needed at this stage of development.

1: environmental pollution. This is the most direct and conspicuous disadvantage.

2: species extinction is accelerating. This is caused by environmental pollution and human hunting. It also belongs to the disadvantage of scientific and technological development.

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 the current new technology. Especially gun crimes, 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. It 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 before. 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.

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 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.

1. Computer: Because of computers, there is a network and online games. Therefore, teenagers cannot extricate themselves, neglect their studies and do nothing. Computer and TV have caused our myopia. If there were no 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. Urban car noise, exhaust pollution and car accidents 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 any living space for human beings? There is a man who wrote an article. He simulated the future. Now people only rely on high technology but are lazy to do it. They get many diseases and lead to human death. Some people may say, without high technology, what should we do if we get sick? Then I tell you, more people die from car accidents than from illness 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 earth's ozone layer by refrigerants, but in recent years, due to the development of refrigerant renewal, this is no longer the main factor. It reduces people's adaptability to the natural environment and reduces 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 Changqi, Japan, have brought 51 years of "terrible peace" to human beings, and for the first time, human beings have the ability to destroy themselves. There are endless nuclear accidents, 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.

5. The appearance of TV and other entertainment facilities 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 air cars, trains, airplanes and other means of transportation has made great changes in human daily life. Humans no longer always rely on their own legs, so the physical quality of human beings now can not be compared with before. Various 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 variation 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, causing precious animals to be endangered; Although cloning technology can save those endangered animals, it is still human beings and human technology that make those animals endangered. In my opinion, the technology of cloning is just that human beings are making up for their own mistakes.

How many amazing changes have taken place in the world when human beings entered the 21th century. While people are delighted with the rapid development of science and technology, they have experienced more disasters. War and disease seem to directly bring mankind into the gates of hell.

thanks to the mobile phone, the user's brain is often exposed to radiation, which is very harmful to the human brain. According to statistics, people's instantaneous memory will drop by 31% if they use mobile phones for more than one hour in a day.

SARS virus in 2113

There was no such word before

Singapore will lower its economic growth forecast in 2113 due to the SARS virus incident

2113-14-19 11: 52

The Singapore government is preparing to lower its economic growth forecast in 2113 because of the spread of severe acute respiratory syndrome (SARS).

Prime Minister Goh Chok Tong of Singapore said that the government could not confirm the full impact of the SARS virus incident on the country, but admitted that the official forecast of Singapore's economic growth of 2%-5% in 2113 would be affected. Goh Chok Tong said a few days ago: "I can say now that the economic growth rate will have to be lowered this year."

severe acute respiratory syndrome (SARS) virus has killed 8 people and infected 116 people in Singapore.

According to Singapore Retailers' Association, the shopping centers were unusually deserted last weekend, although the degree of SARS affected them was different due to different types of goods and locations.

folk analysts revised down their growth forecast for this year by about 1 percentage points on average, considering the double blow of war and SARS to the industry. In the survey of 11 financial institutions in Reuters, the average growth rate is expected to be 2.7% this year compared with last year, while in the survey conducted before the outbreak of the Iraqi war and SARS in October, the expected growth rate was 3.8%.

White pollution mainly refers to two negative

effects of "visual pollution" and "potential harm" to the environment.

"visual pollution" refers to the destruction of the city appearance and landscape by plastic waste scattered in cities. For example, a large number of polystyrene foamed plastic tableware scattered on both sides of railways, rivers and lakes and ultra-thin plastic bags flying all over the sky or hanging on branches have brought bad visual stimulation to people, and people have strongly reacted to it.

"potential crisis" refers to the environmental problems caused by plastic waste entering the natural environment and being difficult to degrade.

Its harm mainly includes the following points:

It is difficult to recycle, because the cost of recycling is high, but the utilization rate is low, so businesses can be said to be unprofitable, and it is difficult to attract the general public to carry out "white recycling" because of its low recycling price. Therefore, it is difficult to recycle.

difficult to degrade. The recovered white waste is not easy to treat. At present, the main treatment methods are incineration and landfill. If it is burned, it will produce a lot of toxic smoke, pollute the atmosphere and promote the formation of acid rain. As for landfill, it will remain intact for 111 years, and it will not be absorbed by nature and will do great harm to the land. Changing its pH value will affect the absorption of nutrients and moisture by crops and lead to the reduction of agricultural production. As for plastic products abandoned in water or land, it will not only affect the environment, but also be passive.
