Students and teachers:
Hello everyone!
Today's society is a society with developed science and technology. It is an indisputable fact that science and technology are developing continuously, which has promoted social progress and facilitated people's lives. But technology is a double-edged sword, which can crush ignorance and backwardness, and at the same time, it can also harm human beings. One case after another shows us the process that science and technology harm human beings, so we think that the disadvantages of science and technology development outweigh the advantages.
First of all, the biggest drawback brought by the development of science and technology is that our personal safety is increasingly 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 at 8: 00 on August 6, 1945, causing 200,000 casualties among 245,000 people in Hiroshima, and the whole urbanization was in ruins.
1August 9, 945, in the early morning 1 1: 02, after the attack on Hiroshima, the US military carried out the second atomic bomb attack on Japan, targeting Nagasaki. The bombing caused more than 654.38+10,000 people of Nagasaki's population of 230,000 to be killed or missing that day, and 60% of the buildings in the city were destroyed.
The injuries caused by the atomic bombings in Hiroshima and Nagasaki have been left to this day, and survivors have suffered from radiation sequelae such as cancer, leukemia and skin burns. As of August, 2007, according to the statistics of relevant Japanese departments, the number of people who died from atomic bombing in Hiroshima and Nagasaki has exceeded 250,000 and140,000 respectively. At the beginning, the development of nuclear weapons made science and technology advance by leaps and bounds. But now, because of nuclear weapons, many people have lost their lives and families.
Coincidentally. Disadvantages brought 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, especially in developing countries, which has increasingly become one of the common topics of all countries in the world. Because people's negative impact on highly developed industries is not expected to be unfavorable, it has led to three global crises: resource shortage, environmental pollution and ecological destruction.
……
To sum up, the disadvantages of scientific and technological development have deeply hurt us human beings and broken the stable development of society. So we think that the disadvantages of scientific and technological development outweigh the advantages.
They do bring a lot of convenience to our lives, but at the same time they gradually lose the basic abilities of human beings. With computers, people no longer think with their brains, because they can do it with computers; With cars, people are no longer used to walking, walking, but driving for a ride; With the dishwasher, people no longer wash dishes by hand. Maybe one day, people will forget how to wash dishes. The development of science and technology is mixed. Happily, it provides the greatest convenience for our life. What is worrying is that one day computers will replace the human brain and machines will replace the hands. By then, the world will no longer be dominated by people who think they are smart, but machines invented by human beings! So I think the development of science and technology will inhibit the all-round development of people, and support will be very harmful.
