Ask, the development of science and technology benefits or disadvantages? There is no doubt, of course, is the benefit! What is the explanation? There is no need to explain! Chinese civilization eight thousand years of history and civilization is ironclad, history is changing every moment, technology is developing every moment. Human beings have learned to utilize or cook food from the primitive life of drinking blood and hair, from relying on nature to breeding and raising, from unarmed iron to metallurgy and stone smelting, isn't this all progress, isn't this all development? If the disadvantages outweigh the advantages, then why do human beings still coincidentally choose progress? Only progress can make tomorrow better!
A person who does not make progress is pathetic, a country that does not make progress is downtrodden, a world that does not make progress is dark. Only in continuous progress can human life be sublimated. Human beings are small, human beings are fragile, he does not have a huge body, does not have the strength like an ox, does not have the hard shell of a tortoise. But God gave mankind a smart brain, a pair of hard-working hands, mankind did not sit back and enjoy the success, but chose to continue to progress, can only stand in the top of the food chain today.
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 condescending; 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, a little bit of the mouse to know the world.
We are happy, we are lucky, we caught up with a high-speed development of science and technology, an era full of high-tech, it is not only our ancestors in the evolution of the choice of development, choice of progress, but also includes all the unremitting efforts, hard work, how many of us today's day when the hard-working scientists with the wisdom of the even life in exchange.
Because of Faraday, we live around the full of a variety of electrical appliances; because Darwin, because Mendel, we can better understand themselves, cognizant of their own; because of magpies, because of Hua Tuo, because Li Shizhen, our lives can be guaranteed.
Aren't they the ones who gave us everything around us in exchange? Life is so comfortable, life is so cozy, life is so wonderful, our average life expectancy is 30 years higher than in ancient times, we don't even have to leave our homes to visit our friends and relatives, isn't it all because of the benefits brought to us by the development of science and technology?
So, science and technology change history, we explore the development of science and technology benefits or disadvantages is no need to question, because it is the benefits! Lei big! Profit big! Technology changes history, good, without the development of science and technology, our lives are unimaginable, our days are dark, is the development of science and technology to save us, is the science to save us from the age of fire and water. We should respect him with a heart of reverence, how can we say that the development of science and technology is full of disadvantages?
Technology changes history, knowledge changes destiny. We have entered the 21st century, into an era full of high-tech. Science has changed our lives, science has changed our destiny. "Knowledge is power", our Chinese people **** and the country, 1.3 billion people of the great country, why can the world in front of the chest up? Because our technology is constantly developing! Our science and technology in constant progress!
The benefits of technological development outweigh the disadvantages, which is an unchanging theme!
Rebuttal
Opponent, you always list all the disadvantages of science and technology, it seems that the development of science and technology has brought nothing but disaster to mankind, then why do we still emphasize that science and technology is the first productive force? Why do human beings continue to develop science and technology?
If there is no science and technology, maybe we are still in the primitive society, then what is the use of a better environment?
Now people in the research of science and technology, not also in the protection of the environment, then how can we say that the research of science and technology must break the environment?
This does not mean that the harms outweigh the benefits, this is only an individual phenomenon, is that they do not use science and technology correctly, this does not negate the benefits of science and technology to mankind.
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 cannot be perfect, the brighter the place behind the shadow of the darker, but on the basis of these you conclude that the development of science and technology does more harm than good? "The world is different things are different" times are different, the problems encountered are also different, and then say the air pollution, the provinces and cities have launched a preventive plan; white trash, unified treatment; automobile exhaust caused by warming scientists have also developed 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?
While there are drawbacks, but compared to the benefit of mankind, environmental protection homes of the concept of scientific and technological development, irrelevant, as long as there are drawbacks, scientists will likewise find a way to solve, we can not choke on food, the pace of scientific and technological development will not stop for a moment. Scientific and technological development, there is no excuse, is the benefit of the big, the only answer to this question! Just because technology has been progressing, science has been developing, cunning sophistry, generalized words, unreasonable nonsense can not change this truth. If you say that technological advances have done more harm than good, ask, 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 a newspaper, reading a book, or surfing the Internet? Can you go a week without eating the hybrid rice you developed? No pasta? No drinks? Can't can't, you can't and can't be able to, because technology is already closely related to you, already inseparable from you! In ask, if you write a letter to the President, said the proposal to stop all scientific research activities, everyone is to give you flowers, or that board special pat you .
It is the development of science and technology to promote the process of mankind, it is the development of science and technology to make mankind have this new and beautiful life. The development of science and technology is the way to strengthen the country, the development of science and technology is the first impetus for the progress of the Chinese nation, no science, where we are today's happy life? Without science and technology, where we have a comfortable material life and spiritual enjoyment? Without the progress of science and technology, how can we eat the hybrid two? How can we wear cotton clothes, how can we live in high-rise buildings?
Human beings have learned to utilize or cook their food from a primitive life of drinking blood and hair, from relying on nature to breeding and raising, from unarmed iron to metallurgy and refining stone, which is not all progress, which is not all development? If the disadvantages outweigh the advantages, then why do human beings still coincidentally choose progress? Only progress can make tomorrow better!
Human beings are small, human beings are fragile, he does not have a huge body, no ox-like strength, no turtle's hard shell. But God gave mankind a smart brain, a pair of hard-working hands, mankind did not sit back and enjoy the success, but chose to continue to progress, so that today can stand in the top of the food chain.
If you say that technological development does more harm than good, ask, can you not take the bus to class within a week, no neutral pen, no ballpoint pen, no pen? Can you go a week without watching TV, listening to the news, reading the newspaper, reading a book, or surfing the Internet? Can you go a week without eating the hybrid rice you developed? No pasta? No drinks? Can you not use an electric rice cooker . Electric lights? No faucet, no washing machine? Can't can't, you can't and can't be able to, because science and technology have been closely related to you, have been inseparable from you! In ask, if you write a letter to the President, said that the proposal to stop all scientific research activities, people are to give you flowers, or that board exclusively shoot you?
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 ......

Leigh: we can go to the places we want to go, people in the continuous exploration in the future may be back to even the "Solar Center" Society was The center of the sun will be overthrown. In the technological development and progress of the present 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 to accelerate the pace of life and improve the standard of living, the amount of plastic
increasing day by day. 1996, China's use of plastic packaging amounted to 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 garbage disposal.
Because waste plastic is difficult to degrade for hundreds of years, if discarded in the natural environment, will give mosquitoes, flies and
bacteria to provide a breeding ground for survival; if buried in the ground, it is easy to contaminate 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 science and technology to benefit. 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, there are more than a dozen manufacturers in China, with an 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, the economic benefits of the company's beginning to take shape. 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 then 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, and has been able to develop the production of biodegradable 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 the various 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 fiber, 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
Land.
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 kinds of 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., said: disposable tableware with rice husk as raw material, not only in our country
resource-rich, inexhaustible, and it can be used after the soil can be quickly degraded, which can be said to be a two-in-one solution.
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 styrofoam 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, give green disposable tableware industrialization to sufficient
enough capital investment.
China's green disposable tableware development 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....
