Disadvantages: 1: Environmental pollution. This is the most direct and prominent disadvantages.
2: acceleration, which is caused by environmental pollution and species extinction of human hunting. The harm also belongs to scientific and technological development.
3: Personal safety is less and less safe. Now every day, on average, tens of thousands of crimes occur. The means of crime at all times with new technologies, especially gun crime, is to catch people off guard, as we can already see from the Second World War, the war brought about by the development of technology, damage and loss is far from being comparable to the previous one, and may even lead to the doom of mankind.
4: human physique and before, with the development of science and technology, gas cars, trains, airplanes and other various means of transportation appear significant changes in human daily life, humans no longer always rely on their own two legs, and thus more than human physique and incomparable. The former Xiang Yu power to pull mountains and rivers and gas cover refueling in today's society no longer appear this situation continues to develop, may lead to atrophy of the limbs, the man appeared, a new form
5: emerging pathogens continue to emerge, a large number of bacterial lethality has far exceeded the previous destructive bacteria, this is due to the rapid development of medical technology, accelerated the virus mutation, the viral variant of the speed has been unable to keep up with the pace of development. Perhaps one day the human race will die out, a specific plague.
And so on and so forth...
For example, we often use computers in our daily lives, but some people don't utilize them properly and wisely, leading to all the failures of the computer talent community at hand. Myopia, addiction, addiction, impact on learning, impact on learning, impact on people's future, the social impact of tomorrow's huge loss! We have seen in the news that some people addicted to computer games, reducing the lead to partners on the street! They were too late after he was arrested ...... In addition to computers, like television and the like can cause people to be nearsighted, nearsightedness can not see what can not be found with the loss of glasses, the consequences can be imagined. Myopia can cause damage to the eyes, and in severe cases can lead to blindness, will be disabled, we so sit back and watch you? Therefore, the disadvantages of developing science and technology! ! !
Invented the plastic bag, but the development of technology, it brings white pollution, it can not be broken, polluting the environment. Specifically as follows:
A plastic bag with low recycling value, in addition to the use of the process of scattering in the city streets, tourist areas, bodies of water, roads and railroads on both sides of the pollution caused by "visual pollution" pollution, but also potentially dangerous. Plastic is structurally stable and not easy to separate in the natural environment for a long time is a natural microbial degradation. This means that if not recycled, waste plastic waste will become pollutants in the environment for a long time and accumulate, causing serious environmental damage.
I, affecting agricultural development. The accumulation of mixed waste plastic products in the soil will affect the absorption of nutrients and water by crops, resulting in crop yields.
Two, the survival of animals poses a threat. Abandoned on land or water waste plastic products, animals as food intake, resulting in animal death. Qinghai Lake last year 20*** there are nearly 1,000 sheep herders thus to, economic losses of about 30 million yuan. Sheep like to eat greasy residue folder wrapped in a plastic bag, but often even plastic bags to eat together, because for a long time to live in the stomach to eat plastic is difficult to digest, these sheep's stomach is crowded, can no longer eat, and finally can only be hungry. Such things are not in the zoo, pasture, rural areas, the ocean is commonplace.
Waste plastics, not only occupy a large amount of land, occupying land can not be recycled in the long term, the impact of sustainable use of landfill land. Waste plastic products into landfills, 200 years without degradation.
The speed of automobile life" or aircraft basically call is to continuously improve the efficiency of people's lives, in this pursuit of efficiency caused by the psychosocial aspects of the anxiety refers to the society has become more impetuous <BR / from the scientific development of the ancient good, to cite some examples such as the United States of America, the Beat Generation from the globalization of globalization of globalization of globalization of the shortcomings of globalization such as the loss of culture under the powerful economic and cultural aggression
consume a lot of the earth's limited material resources, the products of modern science harmful to human health I think the most important bad of this debate
than a list of the various drawbacks that technology has brought to mankind, because if your eyes are only focused on the bad, then the other may catch this to you: the other side of the debate, you always list the various drawbacks of science and technology It seems to be that the development of science and technology has brought nothing but disasters to mankind, why do we still emphasize that science and technology is the first productive force? Why do human beings need to continue the development of science and technology?
Today's society, the rapid development of science, many high-tech products continue to emerge, computers, automobiles, dishwashers, washing machines into the lives of ordinary people, they do a lot of convenience of our lives, but at the same time, they also make the basic human ability to gradually lost. The development of science and technology, let a person happy and sad, happy is that it gives us the greatest convenience of life, sad is that it will one day, instead of letting the computer human brain, the machine instead of hand, the domination of the world is no longer what we think of as a smart person, but human invention of the machine! So, I think: the development of science and technology will inhibit the full development of the human being! Another example, airplanes, rockets, satellites, networks were initially for military wars the same technology to benefit mankind at the same time was used as an accomplice to the destruction of mankind, so we think: mankind enters the 21st century scientific and technological development and shortcomings! How many amazing changes there are in the world, in which people are excited about the rapid development of science and technology, but also experienced better uneasiness and even disaster. In addition to the panic brought about by the development of high technology, especially biotechnology, wars and diseases seem to direct humanity to the gates of hell. The invasion of various viruses, behind the car exhaust, factory exhaust will not help on our beautiful homes to ask why our homes are threatened, why the trees are cut down, why not in the fresh air, it is all that technology can put all the evidence on modern technology to bring us a certain amount of comfort and convenience, but also can be used in a format that I ask them how they intend to be comfortable without a better environment for the Humanity if people don? Hurry up to commit also belongs to the development of science and technology, the wrong remedies, mankind will eventually destroy the technology
: environmental pollution, which is the most direct 2: accelerate the extinction of species, which is caused by the environment when new pollutants and human hunting and killing, harming the most prominent shortcomings.
3: Personal safety and no job security. On average, every day, dozens of thousands of crimes are committed, and most of their crimes are committed by means that are at all times letting the people are very hard from the detection techniques of the Second World War. Gun crime, we have seen the damage caused by war losses now, with the development of science and technology, far more comparable than last year may even cause the doom of mankind.
4: human physique in the human daily life significant changes with the development of science and technology, gas cars, trains, airplanes and other means of transportation came into being, human beings are not so always rely on their own two legs, the human physique than before is not comparable to the previous Xiang Yu force to pull the aerial cover of the mountains and rivers to come in today's society, it is impossible to re-emerge in such a situation to continue to play the role of human beings. Atrophy of the limbs, a new form of human
5. : The emergence of new pathogens continue to emerge, a large number of bacterial lethality has been far more than the destruction of the bacterial team, which is due to the rapid development of medical technology to accelerate the virus mutation, so the pace of scientific development, technology has not kept pace with the speed of the virus mutation. Perhaps one day, the human race will be extinct, especially the plague.
In the primitive era, just the surface of human resources can live, only need to flow of fruit trees, grass seeds and other biological resources, its music thick ah. Later appeared tools and agricultural resources to use the ground to break a foot, and then later coal mines, metals and other resources, at a depth of 100 meters in the end, and then later the depth of up to 5,000 meters, mankind accelerated access to resources to the deep part of the earth, when human beings use the core resources of the earth, the earth will become extinct when the other debates, which is reflected in the development of science and technology will be 1 day to return to the destruction of the ground, that time! It's also smart to be smart!
Science and technology development brings benefits to our lives, we do not deny, but we believe that technology does more harm than good first car is for our travel convenience, arch exhaust caused by pollution of the environment affect human health. Secondly, the emergence of entertainment facilities such as television, to bring convenience to people, communication between people, but the invisible barrier, the advent of the thinning of human feelings. Internet, some unscrupulous elements have the opportunity to disrupt people's lives, bringing a series of so-called high-tech, so the side effects, is undeniable, and requires us how can we turn a blind eye to it?
