The disadvantages that the development of science and technology has brought to mankind

Disadvantages: 1. Environmental pollution, the invention of the automobile has caused air pollution. The invention of mobile phones has caused electronic pollution and nuclear leakage of a large number of discarded mobile phones, causing serious nuclear radiation pollution to the local area.

2. People no longer communicate face-to-face, and the invention of mobile phones has brought great convenience to human communication, but it has reduced human face-to-face communication in real life.

3. The myopic population is increasing rapidly, and computers and mobile phones undoubtedly bring great convenience to people, but their popularity has made more and more myopia patients, and some children are myopic at a young age.

4. Human physical fitness is not as good as before, with the development of science and technology, the emergence of various means of transportation such as automobiles, trains, airplanes and other means of transportation has made major changes in the daily life of human beings, and human beings are no longer always dependent on their two legs, so the physical fitness of human beings is now incomparable with before.

Benefits: 1. The development of science and technology has promoted the process of human beings, and it is the development of science and technology that has enabled human beings to have this new and beautiful life. Throughout the ages, which dynasty and which generation did not attach importance to the development of science and technology, looking back on the past, looking at the four major inventions, unique;Look at the astronomical calendar and be amazed;View Zhaozhou arch bridge, exquisite design;A peek at the Compendium of Materia Medica, Oriental Classics;Look-ahead pi value, seven decimal places;Overlooking the Silk Road, developing the economy;End blue and white porcelain, famous overseas.

2. The development of science and technology is the road to a strong country, and the development of science and technology is the first driving force for the progress of the Chinese nation.

3. The 8,000-year-old history of Chinese civilization is ironclad evidence, history is changing all the time, and science and technology are developing all the time. Human beings learn to use or cook food from the primitive life of drinking blood, from relying on nature to breeding and breeding, from defenseless to metallurgical smelting, this is not all progress, this is not all development, if the disadvantages outweigh the advantages, then why do human beings still choose progress, only progress can make tomorrow better!

With the development of science and technology, the demand for natural resources of human beings is increasing, which makes large areas of forests and grasslands disappear, the land is rapid, and the amount of natural resources of desertification is drastically reduced.

It doesn't allow us to see reality.

Nucleus**. Regarding the disadvantages, Japan** is an example.

Examples of the benefits and disadvantages of technological development:

1. The invention of the automobile has facilitated people's travel, but it has caused air pollution and frequent diseases due to lack of exercise.

2. The invention of mobile phones has brought great convenience to human communication, but it has caused a large number of electronic pollution of discarded mobile phones, as well as the reduction of face-to-face communication in reality.

3. The invention of air conditioning uses people's lives to be more comfortable, but it makes human beings more and more unsuitable for the outside environment.

4. Rational use of nuclear energy to generate electricity for the benefit of mankind, and the Fukushima nuclear leakage has caused serious nuclear radiation pollution to the local area, and the atomic bomb can destroy the earth.

5. Computers have made many file processing more convenient and computing faster, but the popularity of computers has increased the number of myopia patients suddenly.

6. The construction technology is becoming more and more developed, and people are building higher and higher houses, but once natural and man-made disasters (**, fire, etc.) occur, it is more difficult to escape.
