the advantages and disadvantages of science and technology
With the development of science and technology, people's lives have been greatly changed. There is no doubt that we benefit a lot from the scientific advancements in many different ways. For instance, the invention of computers dramatically increases work efficiency and helps complete many difficult tasks that were impossible in the past. Apart from this, new discoveries and technology in medicine improve people's health, which allows them to enjoy a longer life. The progress of science also enlarges human's ablilities to explore the world around them, from up into space to deep under the sea. Thanks to the development of science and technology, human society has enjoyed continuous prosperity and more convenience.
However, just like a double-edged sword, science can cause problems too. It is known to all that the nuclear power, an environmentally friendly source of energy, can also be developed into a weapon of mass destruction. In addition, human cloning, which is expected to cure many serious diseases and save lives, may bring disasters of social morality. As a matter of fact, most of the improvements in science are made at the cost of our precious natural resources and have done great harm to the environment where we live in.
Therefore, how to deal with the progress of science and technology properly is worth our careful consideration.
Nowadays,more and more hi-tech tools,such as calculator,computer,etc,appear in our daily life.we use them wherever and whenever we are,so that our life becomes easier and more comfortable than before.
However,does anyone think about what problems science and technology have caused to happen in this world?To some degree,it's more serious than that we consider.We human indeed use them to improve our living standard,but on the other hand,we are becoming lazier,more reliable than we used to be.All day long those hi-tech products accompany us,then we have either no space or time to think,as well,communication between each other decreases,and what takes place of it is the huge indifference and gap among human. To solve these problems,we should in no time take measures to do with them.Firstly,communicate with others and think on your own more.Secondly,decrease the times you use hi-tech tools.For the advantages of technology,we should absorb,at the meantime,be independent and abandon the short-comings.Thus,we could combine technology and human progress much closer and not lose ourselves in this modern society.
Improvement in science and technology is a double-edged sword, offering comfort and convenience to life, while simultaneously bringing harm and pain to people.
When the development of science and technology brings mankind plenty of profits, it also brings us severely negative effects.
New scientific discovery and technical revolution are changing the social mode of production, promoting the development of the social productivity
With the rapid development of science and technology,people's material and spiritual life have been greatly improved
Modern scientific and technological achievements are widely used to make people's leisure life rich and colorful, such as online games, listening to music, watching movies, etc.
3、极大地开阔了人类的视野和对物质世界的认识水平。improve human's cognitive ability and knowledge
Science and technology has greatly broadened our vision and understanding of the material world level
With the advance of the science and technology, the power of human being to conquer natural disasters is so increasingly improved that the confidence of human is greatly strengthened.
Science and technology make human enjoy better medical conditions
Man's life span has been increased with the advance of the medical science.
1、it can cause global warming,the damage of ecological balance,the
acceleration of species extinction rate and more frequent extreme weather
Technology has widened the gap between rich and poor countries
Modern technology challenges the traditional culture
Modern technology challenges our ethics and morality.
The improvement of science and technology causes negative impacts on human security and peace
Is Science Dangerous
The rapid development of science and technology has brought about great changes to human life, including great harms and disasters .Then people enter into endless argument about whether science is dangerous or not.
So many examples can be figured out to prove the danger of science. Advanced technology can be easily manipulated by irresponsible persons as well as terrorist. Such as the Disaster 911, airplanes fly into buildings, fire burning, huge structures collapse, a lot of victims such as intellectual and business elites were sacrificed. Besides, As technology becomes more powerful day by day , we'll be complacent and lazy. Increased dependency on modern tools like calculators has reduced on our creativity. Students can’t solve a very simple mathematical equation without using a calculator. This affects the way these students uses their brains and reduces on the level of creativity.
Just like the saying goes that every coin has two sides. However, it ‘s obvious that we make the decision to choose which side. After 911, people condemn the terrorist not airplays. Student who got low marks should rethink his carelessness and laziness but not pass the buck to the calculator.
Any way, There is no dangerous science, but dangerous and irresponsible people. We are working very hard to solve such problems that come along with advances in science and technology, but the efforts are not sufficient and not very successful. Actually, the key lies in the user. Moralities such as responsibility, diligence and goodness should never be lost in our heart. Otherwise , the world would be full of danger even we turn back to the stone age.
