On the development of science and technology cons big information

The pros and cons of scientific and technological development

Conclusion: the development of science and technology is important, but can not be reasonable and normal use of the premise of the development, the development of first of all must purify the mind, only no personal thought and mind to get the development and improve the development of high technology can be permanently beneficial to the development of mankind, the harmony of nature!

Cons: the above said that each of us look higher and farther away, which makes us see is just far away from the higher things to explore to pursue, ignoring the immediate do, like those in history who want to find a long life can not be some of the monarchs, drugs are used to manage the disease, the results of their blind investment to go in order to achieve some of the impossible to achieve something, and as a result, the harm to themselves and to the people, as well as the public. The result is that they have harmed themselves and the people, and there are the macro scenes that the people now see in the movies, the chilling burials of the emperors and the so-called wonders of the world.

The development of science and technology has brought convenience and disaster to people at the same time. The first is that we can go where we want to go, people are constantly exploring, in the future may even back to the "Sun Center" will be overturned. In the development and progress of science and technology now no one can enjoy those historical figures can not enjoy things, each newcomer to this world with the development of the economy, the people's pace of life and the improvement of living standards, the amount of plastic

increasing day by day. 1996, China's plastic packaging usage of 2.43 million tons, with an average annual growth rate of more than

20%, especially in the city, Plastic waste in the garbage along the main transportation routes and tourist attractions is increasing rapidly.

According to the survey, the annual output of domestic garbage in Beijing has reached 3 million tons, of which waste plastics account for about 3%, with an annual growth rate of

48%. Coastal cities in the garbage in the plastic component is higher, up to 8-10%. These waste

Plastic in the proportion of garbage if calculated by volume, has reached more than one-third, and greatly increased

The difficulty and cost of waste disposal.

Because waste plastic is difficult to degrade for hundreds of years, if discarded in the natural environment, mosquitoes, flies and

bacteria to provide a breeding ground for survival; if buried in the ground, it is easy to pollute the groundwater, impede the growth of plant roots

Systems, destroying the quality of the soil, affecting the crop yield; if incineration by fire, will produce a variety of toxic gases

Body. "White pollution" has become a major environmental hazard in our society, seriously hampering the sustainable development of our country's

economy and environment.

Currently, the annual consumption of disposable tableware in China is about 10 billion, mainly foamed plastic products, to prohibit

stop the production and sales of these large quantities of disposable foamed plastic tableware, we need to develop and produce alternative

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

and production of green disposable tableware is becoming China's new environmental protection industry.

In mid-December, the Ministry of Science and Technology, in conjunction with the State Economic and Trade Commission, the State Environmental Protection Administration, the Ministry of Railways jointly convened a green disposable tableware technology development and exchange meetings, at which the reporter interviewed the head of the China Rural Technology Development Center

Wang Zhixue, as well as several producers of business managers.

Wang Zhixue said: China's development and production of green disposable tableware according to the type of raw materials, can be divided into paper

pulp, rice husk, straw and starch. China's existing hundreds of enterprises to produce paper disposable tableware,

Annual production capacity of about 3 billion.

Paper tableware raw materials in the production process of serious pollution, high cost, and its own strength and waterproof and wet

poor, therefore, its popularization and application of greater limitations, people will naturally look elsewhere

place, to the benefits of science and technology. Such as rice husk as raw materials for the production of rice husk tableware, China now has more than a dozen of this

type of enterprise, the annual production capacity of about 150 million; straw tableware to crop straw as the main

raw materials, China now also has more than a dozen manufacturers, the annual production capacity of 75 million; starch tableware to potato

starch as the main raw material, it is good degradation, the recovery can do feed. Recycling can be done after the feed. In a word, the country attaches great importance to the research and development of green disposable tableware, through scientific and technological research, Spark Plan, Torch Plan and other scientific and technological development

Development plan to give strong support, many enterprises of the production of green disposable tableware technology has been relatively mature, with

prepared for the foundation of industrialization.

Wuhan Far East Green World Group is to starch as raw material, green disposable tableware technology

Technological research and development, economic benefits of the company's first signs. The company's president Su Xiaohai's experience is quite legendary:

He originally studied arts and crafts in Hubei Light Industry Institute, Wuhan University in 1984 to read a master's degree in philosophy

degree, and then study and work in Germany, Europe's environmental protection has touched him a great deal, and gave birth to return to China to engage in

environmental protection industry idea. Su Xiaohai told reporters: I studied arts and crafts, is a bit of aesthetics, I today

day into the green tableware such as environmental protection business, is the beginning of my initial understanding of the beauty; and aesthetics of the extension

extension of the end of the day is also a philosophy.

Between 1992 and 1996, the Far East Green World Company developed recycled cardboard disposable tableware and reed pulp

molded food and beverage utensils due to the lower technological content and other reasons, the scale of production has not been able to expand. 1996, the company

sent officers to study the European market biodegradable packaging supplies technology, that the development of plant starch production

The company has been working to develop the production of fully degradable packaging products.

Total degradation of disposable tableware products may be a way to eliminate "white pollution". 1997, by a group of food

products, chemical, mechanical experts, the company focuses on investment in the development of a total degradation of disposable food and beverage products, the project

included in the 1997 National Torch Plan project. project.

They absorbed foreign advanced technology, combined with the domestic production process of paper tableware for a series of innovations: the use of

with domestic resources of sweet potatoes, corn and other starch as the main raw material, instead of a single foreign higher-priced

Potato starch; in the raw materials of sweet potato starch increased by 20% of natural fibers, so that catering products increase the strength of the obvious

The company also used foodstuffs and food products to develop a new product line, which was developed by the company.

degree, and then the use of food puffing processing technology to make products with light weight and softness; increase the strength of the surface spraying

processing and shaping equipment, so that the production of food and beverage supplies with waterproof, oil, heat-resistant features and so on. Su Xiaoxiao

Hai made a vivid analogy: it is like the reinforced concrete in the building materials, sweet potato starch is that cement, and

chopped and stirred into a variety of hay and plant roots and stems is that reinforced steel, so as to make the tableware strength obviously

enhanced.

The starch-based tableware products produced by Far East Green World, commissioned by the German SGS organization with reference to the international food

packaging standards for testing, filling in hot water at 100 degrees Celsius and hot oil for more than two hours without deformation, keep

temperature performance is excellent. Because the starch and additives are natural plant materials, the product degradation performance is excellent, by the National Environmental

Environmental Testing Center test shows that about 10 days can be degraded by more than 90%, within a month can be completely degraded.

It is reported that because the project uses plant starch and plant fibers, the cost is low, each with a lid lunch

box cost about 0.12 yuan, no lid lunch boxes and bowls, trays cost about 0.07 yuan, has a broad market prospects.

At present, the Far East Green World Company intends to invest 160 million yuan to build a large-scale fully degradable green disposable tableware production base with an annual output of 5 billion pairs of disposable chopsticks, 3.5 billion various types of

bowls, trays, boxes and other products, and the project, when it reaches production, will be able to

add an annual output of 625 million yuan, and new profits and taxes of about 130 million yuan. The civil engineering of the base has been started in March this year,

has built a standard workshop of 20,000 square meters, if the follow-up funds can be guaranteed, it is expected that the end of 1999 can reach production.

Su Xiaohai said: our scientific and technological advantages are obvious, the future can create the social benefits are also obvious: with starch

made disposable hygiene chopsticks, its functional indicators can completely replace the disposable wooden chopsticks, and only this one, that is

could be the country each year, saving nearly 500,000 cubic meters of timber resources; the group if you can reach the production, it is estimated that each year, we need to use 200,000 tons!

More than 200,000 tons of sweet potatoes are processed into more than 100,000 tons of starch raw materials, which can also lift more than 100,000 people out of poverty in poor areas and promote

the development of agricultural industrialization in old areas.

Shantou Green Heng Industrial Co., Ltd. from the previous few years, the rice husk system of green disposable tableware development, at present

previously also has a preliminary industrial scale production capacity, the company produces a disposable packaging containers made of rice husk, especially

particularly to provide the use of supermarkets and other products such as food packaging containers, has begun to test market Japan, Taiwan, the United States and so on

The company has also started a trial run in the United States and other countries.

The company has already begun trial sales in Japan, Taiwan, and the United States.

The green disposable tableware produced by Green Heng is made by crushing and sifting rice husk, then mixing it with several edible organic

macromolecule bonding agents and water, and then going through the process of stamping and molding, drying, and spraying to produce different shapes of

plates, bowls and other utensils.

Ji Xiaopeng, general manager of Green Heng Business Co. Ltd, said: disposable tableware made from rice husk is not only inexhaustible in our country's rich

resources, but also can be quickly degraded in the soil after it is used, which can be said to be two birds with one stone.

Green Heng has a production line in operation, its investment is about 9.8 million yuan, production capacity of 400,000

tableware/day, currently up to 200,000 tableware/day. Annual output value of about 36 million yuan, the expected payback period of about

one and a half years, investment profit of about 30%, production technology and product quality has passed the Guangdong Provincial Science and Technology Commission organized

Technical appraisal and food hygiene departments of the test. According to reports, the company in order to better market the product, regulation

model operation, intends to set up a group of companies in the near future, and to invest in technological transformation, with a view to making the production

line of higher degree of automation.

According to the Ministry of Science and Technology held under the auspices of the green tableware technology development exchanges, July 18, 1998, Wen Jiabao

Vice Premier of the Taihu Lake Basin Water Pollution Prevention and Control Conference, specifically to solve the Yangtze River, Taihu Lake,

Railway along the "white pollution", and asked the relevant departments of the State Council to focus on three key areas of work. The relevant departments of the State Council were asked to focus on three tasks, one is to strengthen the management,

prohibit littering; the second is to stop the use of disposable foamed plastic tableware; and the third is to develop and mass produce alternatives as soon as possible

Products. The issue of promoting the application of alternatives. It seems that the green disposable tableware has caused the central leadership

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

born and just in time, now, both the need to climb the peak of science and technology personnel to continue to engage in research and development

Development, the need for us to understand the business, good management of entrepreneurs to increase Technological innovation and market development, but also need me

the visionary financiers, venture capitalists to see the pearls, to give the industrialization of green disposable tableware to sufficient

enough capital investment.

China engaged in the development of green disposable tableware and industrialization of most of the enterprises are currently smaller production scale, the ability to resist the wind

Weak, and many of them are private enterprises, the need for government departments to give enough industrial policy

Support and guidance, a better start, so that this emerging green industry can be healthy and sustainable development. The world has a different understanding of our vision farther 1: the benefits of large

In line with the scientific concept of development of scientific development or the benefits outweigh the disadvantages

"A generation of people have a generation of ideological concepts, ways of thinking, regardless of the old experience, or new ideas, each with its own advantages and disadvantages, and can withstand the test of practice, in line with the scientific concept of development, is the right and reasonable! "

Look at the history, from printing to papermaking, from word processors to network consulting **** enjoy, so that the human intellect can be deepened, this is the humanistic power; from the human spiritual value, science and technology to get rid of the poverty of the shroud, the network of scientific and technological information has brought the fourth wave of democracy and human rights to think about the physiological from antibiotics to organ transplants, from water irrigation to biological varieties of the improvement of the human race, all for the Human beings to ease the crisis again and again, when the development of science and technology to bring the deepening of human physiological, psychological and spiritual values, broaden and optimize the time, can still say that the development of science and technology inhibit the overall development of human beings ~

The most direct embodiment of the medical treatment, we are now a healthy person standing here of course, you can rightly say that the scientific development of the disadvantages of the big, because it destroys the environment, so that the earth loaded with a lot of Unnecessary things, but those patients struggling in pain, because there is no scientific development, there is no more advanced medical measures, in the face of them, we can still say environmental protection first? Is life or environmental protection important....

2:Cons

Harm to nature:

Like any industrial product we use, air-conditioning is bound to put a certain burden on our environment. A few years ago, the discussion of the impact of air conditioning on nature was mainly focused on the destruction of the earth's ozone layer by refrigerants, but over the years this is no longer a major factor due to the development of refrigerant renewal trips. The future impact of air conditioning on nature is still reflected in the area of energy consumption, which already accounts for a large share of our total energy consumption in life and industry. Energy consumption and the release of a large amount of heat to the atmosphere, to our natural environment has been a great burden, which is the major problem we have long to solve.

Computer: because of the computer, there is a network, there are online games. Therefore, teenagers can not help themselves, deserting their studies and doing nothing.

Automobile: the population is expanding, if each person has an automobile, do human beings still have room to live?

Air conditioning: reduces the ability of people to adapt to the natural environment and diminishes immunity.

This debate I think the most important thing is not to list all the bad things that science and technology bring to human beings, because if your eyes only focus on the bad things, then the other side is likely to seize this point to attack you: the other side of the debate, you always list all the bad things about science and technology, it seems that science and technology development has brought to human beings only a disaster, so why do we still emphasize that science and technology is the first productive force? Why do we still emphasize that science and technology is the first productive force? Why do human beings continue to develop science and technology?

The key to answering this question lies in your understanding of the topic of the debate, and the essence of this understanding is: why do we need to find out why science and technology bring bad things to people. That's the key to your side's argument, why? Remember there is a saying: technology is a double-edged sword, on the one hand, it can smash ignorance and backwardness, on the other hand, it may also bring endless disasters to human beings. At this time, we emphasize the pain and disaster brought by science and technology to human beings precisely in order to maximize the positive effects of this double-edged sword for the benefit of human beings, rather than the opposite. The so-called "good medicine is better than bad medicine," which is because rational and comprehensive thinking about science and technology can make it always under the control of human beings and will not in turn harm human beings.

After the establishment of the point of view, some necessary examples are naturally to have, in fact, examples are very good to cite: the development of the theory of atomic physics is that mankind has mastered the technology of nuclear energy, but it also brought the Hiroshima and Nagasaki nuclear disaster, brought mankind fifty years of "horrible peace", mankind for the first time with their own destruction of their own ability. For the first time, mankind had the ability to destroy itself. In addition, there have been numerous nuclear accidents, most notably the Chernobyl disaster in the Soviet Union (please search the Internet for specific data). The development of chemistry has allowed us to gain an 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 enabled 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 is due to 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 greatly accelerated we have been able to fly faster than the speed of sound, but this also brought too many wars and too much turmoil, 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, the progress of science is always 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 in our own hands.

The above answer is my answer to the question "What are the disadvantages of science and technology for human beings? These two questions are basically the same, and I don't know if you're describing the question accurately, but if you are, the key point is still how to look at the disadvantages of technology. Is it that there are drawbacks so we don't develop it, or that we would rather return to a primitive society in order to avoid the drawbacks of scientific development. Of course, this is not true, so we find and expose the disadvantages of science and technology in order to play the role of a rational critic, for example, some people found out that Freon is harmful to the ozone layer and did not make human beings stop using refrigerators but use other refrigerants. The discovery of the greenhouse effect of carbon dioxide did not stop the use of the fuel, but the Kyoto Protocol was signed to limit greenhouse gas emissions. The list goes on and on, so your argument is that a rational critic is a rational critic, and it is because of rational critics that mankind has survived self-destruction time and time again. That is your argument. Humanity has always needed some people to play the role of critics, and the core of freedom of speech is to ensure the freedom of those critics, and to guarantee the right of human beings to have different opinions.

I hope this helps you~

Okay!

The most important thing in this debate is not to list the bad things that science and technology have brought to human beings, because if your eyes only focus on the bad things, then the other side is very likely to seize this point to attack you: the other side of the debate, you are always listing all the bad things about science and technology, it seems that science and technology has brought nothing but disaster to human beings, so why do we still emphasize that science and technology is the first productive force?
