Technology is like a double-edged sword? And bring us the gospel? And got into some trouble? Like environmental pollution? Ecological destruction? Social problems such as resource shortage. Nuclear energy can be used to generate electricity? Can also be used to make atomic bombs? Can genetic engineering be used to treat diseases? It can also be used to destroy mankind. If you are engaged in scientific and technological work and lack humanistic care? You may get lost. There are two aspects to the development of technology. It is like a double-edged sword. It can not only benefit mankind by promoting economic and social development, but also bring negative consequences to human survival and development to a certain extent. Science and technology itself is neutral, and its application and development have two sides. On the one hand, because science is perfect in continuous development, it will inevitably bring some bad effects. We can't completely deny science because of this. Is the invention of the car that important? In the developed countries of the world? Cars are essential for almost everyone. However, is this sharp "double-edged sword"? Not only caused frequent traffic jams and traffic accidents? It is also a bottomless pit that consumes energy and a mobile source of air pollution. Even so, we can't deny that it does bring a lot of convenience to mankind. Just because people haven't found better technology to develop it. Freon has made the dream of sitting comfortably come true? But ironically? Freon was first invented as a refrigerant? On the one hand, it has raised human life to a higher level? At the same time, it has also brought about a growing hole in the ozone layer? Even if we stop using freon now? It was not until the middle of this century that the damaged ozone layer was restored. DDT used to be the darling of farmers all over the world? Even after World War II, it showed magical effects in controlling diseases? But it is this so-called precious wealth of mankind, an epoch-making DDT invention? In fact, it has become the chief culprit in destroying ecological chain, destroying animal and plant populations and endangering human health. Now? Although DDT is banned all over the world? But its residual poison still stubbornly stays in the circulation of nature? Even penguins in the Antarctic are born to die. Is the battery really an important invention of mankind? It can meet people's needs. Bring light and strength to mankind anytime and anywhere. However? Is it the fact that batteries pollute the environment that makes more and more people have to pay attention to it? Humans may enjoy the benefits of batteries for more than 200 years? But it will take more and longer! The invention of mobile phones has undoubtedly brought more convenience to this rapidly changing information society? However, just when mobile phones are popular with people? Can the radiation of mobile phone radio waves harm human DNA and kill the cell repair system of tumor? Inconsistent rumors are flying everywhere? It makes people wonder who to trust. Just like everything has two sides, modern science and technology also has negative effects on the human social environment, which is mainly manifested in the unity of utilization and destruction of environmental resources. For a long time, people only pay attention to the functional role of science and technology in development and application, which can provide people with great energy and high efficiency in the process of transforming resources into wealth, so they hail the victory of science and technology in conquering nature ... With the development of modern science and technology? The duality of science and technology has been paid more and more attention by academic circles. When people use chemical pesticides without restriction in order to achieve high yield of crops? The singing of birds in nature and the fish, shrimp and shellfish swimming back in the stream? But away from us? When we enjoy cheap and inexhaustible nuclear energy. Our lives are threatened by radioactive pollution? When people can easily isolate, splice and recombine genes? We are faced with changing the genes of living things, changing species? Even change the mutant race? When we advocate the dignity of death. It is also possible that some people use euthanasia to murder patients for their own benefit? When network technology greatly shortens people's communication distance? The virtuality of the network leads to the proliferation of pornography, hatred and information pollution? People's sense of right and wrong, sense of responsibility and dignity have all been forgotten. High-tech ethical issues that we always thought had nothing to do with? But directly exposed to every ordinary person. The development of science and technology has promoted the progress of mankind? It is the development of science and technology that gives mankind this brand-new and beautiful life. [1] Throughout the ages? Which generation doesn't pay attention to the development of science and technology? Look back? See the four great inventions? Unique? Look at the astronomical calendar? Is Marvel Comics here? Browse Zhaozhou Arch Bridge? Exquisite design A glimpse of Compendium of Materia Medica? Oriental canon? What is the value of pi? Seven decimal places? Overlooking the Silk Road? Develop the economy? Blue and white porcelain? Famous overseas scientific and technological development is the road to a strong country? Scientific and technological development is the first driving force for the progress of the Chinese nation? No science? Where did our happy life come from today? No technology? Where do we get comfortable material life and spiritual enjoyment? Although we humans can't put an end to the negative effects brought by science and technology? But in a way? Human beings can develop through scientific development and technological innovation? Reduce the negative impact of science and technology. So what? We have the technology? We should try our best to reduce the negative effects of science and technology. Just respect nature, okay? Act according to the laws of nature? I think we humans can still develop in harmony with nature.
