The injury cases caused by science and technology should be real cases.

Advantages and disadvantages of scientific and technological development

Conclusion: Although the development of science and technology is important, it cannot be developed on the premise of reasonable and normal use. Development must first purify the mind. Only when no one's mind and soul are developed and improved can the development of high technology be beneficial to human development and the harmony of nature forever!

Disadvantages: As mentioned above, everyone's eyes are higher and farther, which makes us only see higher things in the distance, explore and pursue, and ignore what we should do at present. Just like some monarchs in history who want to live forever, they use drugs to treat diseases, and as a result, they blindly invest to realize some impossible things. As a result, they hurt others and themselves, and the macro scene that people see in movies now appears.

The development of science and technology not only brings convenience to people, but also brings disaster. Benefits: We can go where we want to go, people are constantly exploring, and the association of the Sun Center may be overthrown in the future. Nowadays, with the development of science and technology, no one can enjoy those things that historical figures can't enjoy, but every new person is interested in this world with the development of economy, the acceleration of people's living pace, the improvement of living standards and the amount of plastic.

Increasing day by day. 1996, China's plastic packaging consumption reached 2.43 million tons, with an average annual growth rate exceeding.

20%, especially in cities, major traffic routes and tourist attractions, plastic waste is increasing 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%, increasing year by year.

The growth rate is 48%. The plastic content of garbage in coastal cities is higher, reaching 8- 10%. These wastes

If the proportion of plastic in garbage is calculated by volume, it has reached more than one third, and it has greatly increased.

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 give mosquitoes, flies and

Bacteria provide a hotbed for survival and reproduction; If buried underground, it is easy to pollute groundwater and hinder plant roots.

The growth of strains destroys soil quality and affects crop harvest; If you burn with fire, it will produce a variety of toxic gases.

Body. "White pollution" has become a major public hazard that harms the social environment of China and seriously hinders the development of China.

Sustainable development of economy and environment.

At present, the annual consumption of disposable tableware in China is about10 billion, mainly foam plastic products, which should be banned.

To stop the production and sale of these disposable foamed plastic tableware, it is necessary to develop and produce its substitutes.

Articles, green disposable tableware came into being. Experts believe that the development of green disposable tableware

And production is becoming a new environmental protection industry in China.

In mid-February, the Ministry of Science and Technology, the State Economic and Trade Commission, the State Environmental Protection Administration and the Ministry of Railways jointly held the Green One.

At the second tableware technology development exchange meeting, the reporter interviewed the person in charge of China Rural Technology Development Center.

Wang Zhixue and the managers of several production enterprises.

Wang Zhixue said: At present, the green disposable tableware developed and produced in China can be divided into paper according to the types of raw materials.

Pulp, rice husk, rice straw and starch. There are hundreds of enterprises producing paper disposable tableware in China.

The annual production capacity is about 3 billion.

The raw materials of paper tableware are seriously polluted in the production process, with high cost, high strength, water resistance and moisture resistance.

Poor sex, therefore, its popularization and application have great limitations, and people naturally look to others.

For example, there are more than a dozen rice husk tableware made of rice husk in China.

Enterprise type, the annual production capacity is about 65.438+0.5 billion; Straw tableware is mainly made of crop straw.

Raw materials, at present, there are more than a dozen domestic manufacturers, with an annual production capacity of 75 million; Starch tableware is potatoes.

Starch is the main raw material, which has good biodegradability and can be used as feed after recovery. In a word, the state cares about environmental protection.

The research and development of recycled tableware is very important, through scientific and technological research, spark plan, torch plan and other scientific and technological development

The exhibition plan gives strong support, and the production technology of green disposable tableware in many enterprises is relatively mature, with

Laid the foundation for industrialization.

Wuhan Far East Green World Group Co., Ltd. takes starch as raw material to tackle scientific and technological problems of green disposable tableware.

Close and develop companies whose economic benefits have begun to take shape. Su Xiaohai, the president of this company, has a legendary experience:

Formerly majoring in arts and crafts in Hubei Institute of Light Industry, 1984 entered Wuhan University to study for a master's degree in philosophy.

After studying and working in Germany, environmental protection in Europe touched him greatly, so he went back to China to do it.

The concept of environmental protection industry. Su Xiaohai told reporters: I have studied arts and crafts and am an aesthete.

Tian's commitment to environmental protection such as green tableware stems from my initial understanding of beauty; And the extension of aesthetics

Extension, in the final analysis, is also a philosophy.

From 1992 to 1996, the recycled cardboard disposable tableware and reed pulp developed by Far East Green World Company.

Due to the low technical content, the production scale of molded tableware has not been expanded. 46860 . 6868686866 1

The company sent staff to inspect the technical situation of biodegradable packaging products in the European market and thought that the production of plant starch should be developed.

The complete degradation of disposable tableware may be a way to eliminate the "white pollution" .4438+0997, a batch of food

Specialists in products, chemistry and machinery, the company focuses on the development of fully degradable disposable catering supplies, among which

Included in 1997 national torch plan project.

They absorbed foreign advanced technology and combined with domestic paper tableware production technology to carry out a series of innovations: efficiency

Starch such as sweet potato and corn, which are rich in domestic resources, is used as the main raw material, rather than a single foreign starch with higher price.

Potato starch; 20% natural fiber is added into sweet potato starch raw material, which makes the tableware obviously stronger.

Degree, and then use the processing technology of food expansion to make the products light and soft; Surface spraying to increase strength

Processing and molding equipment makes the produced catering products waterproof, oil-proof and heat-resistant. Xiao Su

The sea made a vivid metaphor: it is like reinforced concrete in building materials, sweet potato starch is cement, and

The root of all kinds of hay and plants is steel bars, so the strength of tableware can be obvious.

Enhance.

The tableware products with starch as raw material produced by Far East Green World are entrusted to SGS in Germany for reference to international food.

According to the packaging standard test, hot water and hot oil stored at 100℃ for more than two hours will not deform at all.

Excellent temperature performance. Because starch and additives are natural plant raw materials, the product has excellent degradation performance and has been approved by the state

Environmental testing center shows that it can degrade more than 90% in about 10 day, and it can be completely degraded within one month.

According to reports, because the project uses plant starch and plant fiber, the cost is low, and everyone has rice.

The cost of boxes is about 0. 12 yuan, and the cost of uncovered lunch boxes, bowls and plates is about 0.07 yuan, which has a broad market prospect.

At present, Far East Green World Company plans to invest 65.438+0.6 billion yuan to build an annual output of 5 billion pairs of disposable chopsticks and 3.5 billion pairs of chopsticks.

A large-scale fully degradable green disposable tableware production base for bowls, plates, boxes and other products can be used every year after the project is completed.

The new output value is 625 million yuan, and the new profit and tax is about 65.438+300 million yuan. The civil engineering of the base started in March this year.

A standard factory building of 20,000 square meters has been built. If the follow-up funds can be guaranteed, it is estimated that 1999 will be put into production by the end of this year.

Su Xiaohai said: Our scientific and technological advantages are obvious, and the social benefits we can create in the future are also obvious: using starch.

The functional index of disposable sanitary chopsticks can completely replace disposable wooden chopsticks, with only one item per year.

Can save nearly 500 thousand cubic meters of wood resources for the country; If the group can produce, it is estimated that it will use 200,000 tons per year.

More than 654.38 million+tons of sweet potatoes can be processed into starch raw materials, and more than 654.38 million+people in poverty-stricken areas can be lifted out of poverty and promoted.

Enter the development of agricultural industrialization in the old areas.

In the past few years, Shantou Heng Lv Industrial Co., Ltd. began to develop green disposable tableware made of rice husk.

I also had the ability to produce on an industrial scale before. The disposable packaging container of rice husk produced by this company is special.

In particular, products such as food packaging appliances used in supermarkets have been tried out in Japan, Taiwan Province Province and the United States.

Land.

The green disposable tableware produced by Heng Lv Company is made by crushing and sieving rice husk and then mixing it with several edible ones.

Organic polymer adhesive is mixed with water, and then processed into different shapes by stamping, drying and spraying.

Plates, bowls, etc 。

The general manager of Kyrgyzstan Commercial Co., Ltd. said: Disposable tableware is made of rice husk, which is not only owned by our country.

The source is abundant and inexhaustible, and it can be quickly degraded in the soil after use, killing two birds with one stone.

At present, Heng Lv Company has a production line running, with an investment of about 9.8 million yuan and a production capacity of 400,000 yuan.

Tableware/day, currently reaching 200,000 tableware/day. The annual output value is about 36 million yuan, and the estimated payback period is about.

In one and a half years, the investment profit is about 30%, and the production technology and product quality have passed the Guangdong Provincial Science and Technology Commission.

Technical appraisal and inspection of food hygiene department. According to reports, in order to better market products, the company has standardized

Mode management, plans to set up a group company in the near future, and invest in technical transformation to make production.

The production line is more automated.

According to the introduction of green tableware technology development exchange conference sponsored by the Ministry of Science and Technology, July 1998, Wen Jia.

At the meeting on water pollution prevention and control in Taihu Lake Basin, Vice Premier Bao made it clear that,

The "white pollution" along the railway requires the relevant departments in the State Council to focus on three tasks: first, strengthen management,

No littering; Second, stop using disposable foamed plastic tableware; Third, develop mass production substitution as soon as possible.

Products. 165438+1October 14, vice premier Li Lanqing at 12 national patriotic health campaign committee working conference, also

This paper puts forward the popularization and application of foam plastic tableware substitutes. It seems that green disposable tableware has attracted the attention of the central government.

Leading comrades, science and technology, environmental protection and other relevant departments attach great importance to it. As a new environmental protection industry, it can be described as

Born at the right time, now, we need scientific and technological personnel who can climb the peak of science to continue to engage in research and development.

Hair, we need entrepreneurs who know how to operate and manage to increase the intensity of technological innovation and market development, and we also need me.

Our far-sighted financiers and venture capitalists have a vision, which gives enough space for the industrialization of green disposable tableware.

Sufficient capital investment.

Most enterprises engaged in the development and industrialization of green disposable tableware in China have small production scale and poor wind resistance.

Inspur's ability is weak, and many of them are private enterprises, which need government departments to give enough industrial policies.

With the support and guidance, we will have a good start and make this emerging green environmental protection industry develop healthily and continuously. With a different understanding of the world, we look further: Lida.

In line with the scientific development of Scientific Outlook on Development, the advantages outweigh the disadvantages.

"A generation has a generation of ideas and ways of doing things. Both old experience and new ideas have their advantages and disadvantages. It can stand the test of practice, conforms to Scientific Outlook on Development, and is correct and reasonable! "

Throughout history, from printing to papermaking, from word processor to network consultation, human intelligence has been deepened, which is the humanistic motivation; In terms of human spiritual values, science and technology have helped people get rid of poverty, and network scientific and technological information has brought the fourth wave of thinking about democracy and human rights. Physiologically, from antibiotics to organ transplantation, from irrigation to the improvement of biological varieties, it has solved the crisis for mankind again and again. When the development of science and technology deepens, broadens and optimizes people's physiological, psychological and spiritual values, can it be said that the development of science and technology inhibits people's all-round development?

The most direct embodiment is medical treatment. We are a healthy person standing here now. Of course, we can say that scientific development is harmful because it destroys the environment and adds many unnecessary things to the earth. But those struggling patients, because there is no scientific development and no more advanced medical means, can we still say that environmental protection comes first? Is life important or environmental protection important?

2. Great shortcomings

Damage to nature:

Like any industrial product we use, air conditioning will inevitably bring a certain burden to our environment. In the past few years, the impact of air conditioning on nature mainly focused on the destruction of the earth's ozone layer by refrigerants, but these years, due to the development of refrigerant renewal, this is no longer the main factor. In the future, the impact of air conditioning on nature will still be reflected in the field of energy consumption, which has accounted for a large proportion of our total energy consumption in life and industry. The development of energy and the release of a large amount of heat into the atmosphere.

Computer: Because of computers, with the internet and online games, teenagers can't extricate themselves, neglect their studies and do nothing.

Car: With the population expanding, if everyone has a car, can human beings still have living space?

Air conditioning: it reduces people's adaptability to the natural environment and reduces immunity.

I think the most important thing in this debate is not to list all kinds of disadvantages brought by science and technology to mankind, because if your eyes are only fixed on the disadvantages, then the other party is likely to seize this point and attack you: your opponent, you always list all kinds of disadvantages of science and technology, as if the development of science and technology has only brought disasters to mankind, so why are we still emphasizing that science and technology is the primary productive force now? Why should mankind continue to develop science and technology?

The key to answering this question lies in your understanding of the debate. The essence of this understanding lies in: Why should we find out the disadvantages brought by technology? This is the key to your point of view. Why? I remember a saying: technology is a double-edged sword. On the one hand, it can crush ignorance and backwardness, on the other hand, it may bring endless disasters to mankind. At this time, we emphasize the pain and disaster that technology has brought to mankind, precisely for this double-edged sword to maximize its positive role in benefiting mankind, not the other way around. The so-called good medicine is good for the disease, because rational and comprehensive thinking on technology can always keep it under the control of human beings and will not harm human beings in turn.

After the viewpoint is established, some necessary examples are naturally indispensable. In fact, the example is very good: the development of atomic physics theory has enabled mankind to master nuclear energy technology, but it has also brought about nuclear disasters in Hiroshima and Nagasaki, which has brought "terrible peace" to mankind for 50 years. For the first time, human beings have the ability of self-destruction. In addition, there are endless nuclear accidents, the most famous of which is Chernobyl in the Soviet Union (please search online for specific data). The development of chemistry has given us 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 are so many children suffering from leukemia in our country now? A very important factor is the chemical adhesive used in home improvement. Some fluoride ions will destroy the ozone layer. The development of petroleum exploration technology has greatly accelerated the pace of human progress. We have been able to fly faster than the speed of sound, but it has also brought too many wars and too many disturbances, and it has also made the earth catch a cold and have a fever. The development of biotechnology has given us the power to create life that was monopolized by God before, but it has also brought about ethical disorder. In short, scientific progress is always accompanied by corresponding disadvantages and dangers. Today, we must face up to these negative effects, otherwise we humans may eventually be destroyed by ourselves.

The above answer is my answer to "the disadvantages brought by technology". These two debates are basically the same. I wonder if your debate is accurate. If so, then the key point of this debate is how to treat the disadvantages of technology. If there are disadvantages, we will not develop, or in order to avoid the disadvantages brought by scientific development, we would rather return to the primitive society. This is of course incorrect, so we discover and expose the disadvantages of science and technology in order to play the role of a rational critic. For example, it was found that the harm of freon to the ozone layer did not stop people from using refrigerators, but used other refrigerants. After people discovered that carbon dioxide would have a greenhouse effect, they did not stop using related fuels. However, the Kyoto Protocol was signed to limit greenhouse gas emissions. There are countless similar examples, so your point of view is rational criticism. It is precisely because of rational criticism that human beings have survived from self-destruction again and again. This is your argument. The development of human beings always needs some people to play the role of critics, and the core of freedom of speech is to ensure the freedom of those critics and the right of human beings to obtain different opinions.
