The development of science and technology has great advantages and disadvantages

The biggest drawback brought about by the development of science and technology is that our personal safety is becoming more and more insecure. In World War II, in order to force Japan to surrender quickly, the United States dropped a uranium bomb codenamed "Little Boy" on Hiroshima City at 8:15 on August 6, 1945, killing and injuring 200,000 of Hiroshima's 2450,000 people, and the entire city was reduced to rubble.

At 11:02 a.m. on August 9, 1945, following the attack on Hiroshima, the U.S. military carried out a second atomic bomb attack on Japan, targeting Nagasaki. More than 100,000 people out of a population of 230,000 in Nagasaki City were bombed and disappeared on the same day, and 60 buildings in the city were destroyed.

The damage caused by the atomic bombings of Hiroshima and Nagasaki remains to this day, and survivors suffer from the after-effects of radiation such as cancer, leukemia and burns. As of August 2007, according to statistics from the relevant Japanese authorities, the number of deaths in Hiroshima and Nagasaki as a result of atomic bombs** exceeded 250,000 and 140,000 respectively. At the beginning, the nuclear ** was developed, which made a leap forward in science and technology.

But now, because of nuclear **, many people have lost their lives and families.

Drawbacks brought about by the development of science and technology: With the development of science and technology and the improvement of people's living standards, environmental pollution is also increasing, and the problem of environmental pollution has increasingly become one of the common issues of all countries in the world. The negative impact of highly developed industry was not anticipated enough to prevent adverse effects, leading to three major global crises:

Resource shortage, environmental pollution, ecological destruction.

They do bring a lot of convenience to our lives, but at the same time, they also cause the gradual loss of basic human capabilities. With computers, people no longer use their human brains to think about things, because they can do it with just a computer; With cars, people are no longer used to walking and walking, but instead drive around; With dishwashers, people no longer use their hands to wash dishes, and maybe one day humans will forget how to wash dishes.

Bottom line: Which of you didn't have information through technology?? I'm also in 6th grade.

It must be Lida, you're in the sixth grade, we're all out, and you're in the same grade.

I don't have your information @ on the other side

It's a philosophical question :

The reason why science is developing is that human beings are progressing, and this is a good thing that should be used correctly. On the contrary, if you want to develop, you will produce things that conflict with development, such as the environment, ****, etc., depending on how you use it and where you use it. This can also be said to be a contradiction.

--Original. Absorb everyone's opinions.

The way of life of the class, 200,000 years ago compared to 100,000 years ago

Of course, the advantages outweigh the disadvantages, the rapid development of science and technology, our daily life is accompanied by technology products everywhere, we use mobile phones, computers, including the skyscraper you are in now, these are not all scientific and technological products, imagine that if there is no electric light invented by Edison, then the night is pitch black, people have half of the time to do nothing, wasted, no cars, trains, planes, ships, you want to eat a fresh green vegetable in winter, and when it is shipped from the south, isn't it all rotten, Don't say you can grow in a greenhouse, isn't that also an accessory product of technology! Technology is not only "high" technology such as space shuttles, rockets, atomic bombs, etc., but also has a side that is close to life. If the development of science and technology really does more harm than good, will the country still advocate the rejuvenation of the country through science and technology?

If it really does more harm than good, and no longer develops science and technology, China will not be as backward and beaten as the Qing Dynasty! If it really does more harm than good, then why are you surrounded by tech ancillary products! The reason why human society has grown and prospered now is not the development of society driven by science and technology.

If you say that the development of science and technology has brought environmental pollution and endangered human health, it can only mean that the development of science and technology has not been completely removed, so we must develop science and technology until all the *** completely disappears. If you say that the Internet pollutes people's eyes, but why do you say that computers should start from the baby! That is, to tell us that there are things we want in the network, and those bad things on the network are not the fault of technology, but the fault of people!

If you don't put it on, he won't synthesize it himself! Don't say that technology brings this bad and that bad! Isn't that what people do to break the law and make huge profits?

When we say that the development of science and technology has brought us a lot of drawbacks, then we must seriously think about whether the people who use it have a clear conscience! Don't blame all the mistakes on technological development!

There are pros and cons to each other, such as ***: it is convenient to use it to transport goods, but people on the ground feel very noisy (noise pollution): the plane used for the performance:

So that the performance is no longer monotonous, but there is too much smoke coming out. Car: Traveling long distances is time-saving and labor-saving.

It emits exhaust fumes. So, there are pros and cons to each.

We all agree that the benefits of scientific and technological development outweigh the disadvantages.
