What information is there about the disadvantages of technological development 20

1. As mankind enters the 21st century, how many amazing changes have taken place in the world. While people are happy about the rapid development of science and technology, they have also experienced better unrest and even disaster. In addition to the panic caused by the development of high technology, especially biotechnology, war and disease seem to have led humanity directly to the gates of hell.

The invasion of various viruses, the exhaust fumes behind the car, the exhaust fumes of the factory, etc., are infringing on our beautiful home. Why our homes are threatened, why trees are being cut down in large numbers, why the air is not fresh, all of these are the evidence of the crimes brought about by technology. Modern technology has brought us some comfort and convenience, but at the same time, it has also brought a wide range of impacts, how can human beings survive comfortably without a beautiful environment?

If people don't hurry to remedy the mistakes they have made, humanity will eventually be destroyed by technology.

2. The development of science and technology has brought benefits to our lives, which we have not denied. But we believe that the disadvantages of technology outweigh the benefits. First of all, although the car is convenient for us to travel, the exhaust gas of the archway causes environmental pollution and affects human health.

Secondly, the emergence of entertainment facilities such as television, although it has brought convenience to people, has invisibly blocked the communication between people, and it is a weak human relationship. There is also the emergence of the Internet, is that some criminals have the opportunity to disrupt people's lives and so on a series of your so-called high-tech ***, is undeniable, how can we sit idly by?

3. What the opponent's defense friend just mentioned is just a hypothesis Please go back to reality, if there is no obstacle from science and technology, and what is the need to spend so much effort to publicize and protect the environment? Besides, the current problem of the Internet is exactly what everyone is worried about, and the Internet is the reason why many teenagers who are supposed to be the flowers of happiness of the motherland have gone astray and embarked on the road of crime You said that although the Internet can make it easier for us to find information, how can such a small advantage be compared with the future of the motherland?

4. The Internet problem is very important, young people are the flowers of the motherland, the future of the motherland depends on the young people, the Internet leads the teenagers into disorientation, and the Internet has harmed how many teenagers cannot extricate themselves, if the next generation of the motherland is addicted to the Internet, then how can our motherland have more dreams to realize?

5. In the primitive era, human beings only need the resources on the surface of the earth to live, only need streams, fruit on trees, grass seeds and other living resources can also be happy and strong Later, tools appeared, and then breeding, resource utilization to break the ground a foot, and then coal mines, metals and other resources went deep into the bottom 100 meters, and then 5000 meters deeper, human beings accelerated to the deep earth to ask for resources, when human beings use the earth's core resources, the earth will also come to extinction, the other side of the debate, This is enough to show that the development of science and technology will one day destroy the earth, and when the time comes, it will be smart but will be mistaken by cleverness!

Hope it helps.

In 1909, Beckland in the United States synthesized phenolic plastics for the first time. In the thirties of the 20th century, nylon was introduced again, and it was said to be "a fiber made of coal, air and water, thinner than spider silk, harder than steel, and superior to silk". Their appearance laid the foundation for the invention and production of various plastics later.

Due to the development of the petrochemical industry in World War II, the raw material of plastics was replaced by coal, and the plastic manufacturing industry also developed rapidly.

However, less than 100 years after the invention of plastics, if people were ecstatic about their creation, now they have to take great pains to deal with these things that pervade life and pose a great threat to the human environment. In 2008, supermarkets said that plastic bags were chemical petroleum products extracted from petroleum or coal, and once produced, it was difficult to degrade naturally. Plastic buried in the ground for 200 years will not decay and degrade, a large amount of plastic waste buried in the ground, will destroy the permeability of the soil, make the soil compact, affect the growth of plants.

Livestock can also die from digestive tract obstruction if they accidentally ingest plastic that has been mixed with feed or left in the wild.

At present, many countries use incineration (thermal energy regeneration) or reprocessing manufacturing (product recycling) to dispose of waste plastics. These two methods enable waste plastics to be recycled and achieve the purpose of saving resources. However, due to the fact that waste plastics will produce harmful gases to the human body and pollute the environment when they are incinerated or reprocessed, it can be said that the disposal of waste plastics is still a major headache in environmental protection work.
