With the rapid development of science and technology, the advantages and disadvantages of science and technology have become a hot topic. It can benefit mankind and make the future of mankind brighter, but at the same time it is a double-edged sword. In recent years, some people have been saved by it, and others have been deeply hurt by it. How to make use of scientific and technological achievements has obviously become a big problem. The times are changing with each passing day, science and technology are advancing by leaps and bounds, and the world is undergoing earth-shaking changes. Technology has brought people too much thinking.
In ancient times, if people were not together, it was difficult to get in touch. If people are thousands of miles away, communication will be very troublesome. However, with the rapid development of the Internet, the earth has become a small village, and you can keep in touch with your relatives thousands of miles away anytime and anywhere. Not only that, there are various ways of communication now, such as sending messages, making phone calls, voice chatting and video calling, but in the past there was only one way to write letters.
In ancient times, human lighting was very troublesome, and there were always many hidden dangers, because candles were open flames, and if they were placed near flammable materials, they would bring endless trouble if they fell. Since Edison invented the electric light, light has been everywhere, and all kinds of lights are beautiful. Brightly lit and never extinguished, it has become a unique night scene of modern cities.
In the past, people living at the bottom of society were not only underfed and clothed, but also sick. At that time, people were weak, not as tall as they are now, not to mention weight, and even the maternal and infant mortality rate at birth was very high. The poor live in fear of diseases and incurable diseases. Now medicine is very developed, and only a few diseases can't be solved, and I believe that in the near future, people will definitely break through the remaining medical difficulties.
Of course, the harm brought by technology is not small. Weapons are very developed now. If war really breaks out, the consequences will be unimaginable, and mankind is likely to perish.
Even without lethal weapons, the survival and security of human society are very worrying. In the modern society with advanced science and technology, many people are reluctant to take part in activities with the convenience of take-away and express delivery, and their physical fitness is getting worse and worse. When the physical quality is poor, the external environment is destroyed, which objectively threatens people's health again. We also know that industrial pollution, automobile exhaust and other factors are ultimately caused by scientific and technological development.
The harm brought by science and technology goes far beyond these. If humans continue to use chemicals indiscriminately, it will be an inevitable outcome to go to extinction.
Einstein once said: "Science is a powerful tool. How to use it, whether it brings happiness or disaster, depends on people themselves, not tools. " I think human beings should make good use of the power of science and technology to improve the sense of security and happiness in modern society; If the power of science and technology is not used properly, the earth will be destroyed.
Shenzhou spaceship is coming to us leisurely, and its smile is filled with our confidence and joy in China. The flight of "Shenzhou 5" tells the world that we China people can fly and explore in space by our own efforts and realize the beautiful dream of "the Goddess Chang'e flying to the moon".
China people's dream of flying for thousands of years has finally come true. Shouldn't we be confident? Although, at present, China's space technology can't travel in the sky like the United States. But I believe that with the unremitting efforts and exploration of scientists, the dream of "flying freely" in the sky will definitely come true in the near future.
The maglev train played its cheerful "song" like an arrow leaving the string. Now that we have highways, planes and maglev trains to choose from, who will feel the hardship of getting involved in long-distance travel? Not to mention the maglev train. Take the plane we are familiar with as an example. Everyone will sincerely thank it for its great convenience.
I remember that the 5 12 Wenchuan earthquake suffered heavy casualties and the situation was critical. If emergency medicine and daily necessities were not transported by plane, who knows how many dead people would float into the sky? Yes, airplanes give us hope to survive in times of crisis. Besides, you were just planning to go somewhere, got on that train and woke up to find that you had reached your destination, which made us wonder if you were dreaming. However, this is the reality, and the development of science and technology has given us a fantastic reality.
Look again, turn on the networked computer, and we can roam freely in this information society. As long as you are gentle, all kinds of service information will be presented to you, and you will see a clear correlation diagram. You no longer have to swim in the ocean of books for some difficult problems like before, looking at thick information books and not knowing where to start.
Now as long as you turn on the computer video, you can chat with friends and relatives far away, just like being around. Tightening the vast land in the network really feels like "scholars don't go out, and the world knows it." I can't help but say softly, "Oh, this is the convenience brought by scientific and technological progress."
And all this is not enough to show that the development of science and technology has brought great progress to our society? Greatly improved our living standards.
Science and technology are developing and society is progressing! Our world is more wonderful because of the development of science and technology.
