Disadvantages: environmental pollution. This is the most direct and obvious disadvantage.
2. Species extinction is accelerating. This is caused by environmental pollution and human hunting. It also belongs to the disadvantages of scientific and technological development.
3. Personal safety is increasingly insecure. Now tens of thousands of crimes occur on average every day. Most of their criminal methods are related to the current new technology. Especially gun-related crimes, ordinary people can't prevent them. From the Second World War, we can already see that with the development of science and technology, the damage and losses caused by the current war are far from comparable. It may even lead to the fate of human extinction.
Human's physical quality is not as good as before. With the development of science and technology, the emergence of vehicles such as air cars, trains and planes has greatly changed human daily life. Human beings are no longer always dependent on their own legs, so the physical quality of human beings is not comparable to that in the past. In today's society, it is impossible for Xiang Yu to "pull out mountains and rivers". If this situation continues to develop, it may make people's limbs atrophy and make people appear.
5. All kinds of emerging germs appear constantly, and the lethality of many germs has far exceeded the destructive power of previous germs. This is because the rapid development of medical science and technology has accelerated the mutation of virus, so that the development speed of science and technology can not keep up with the mutation speed of virus. Maybe one day mankind will perish because of a great plague.
6. Cloning technology has appeared in today's society. There is a lot of controversy about human cloning now. First of all, human cloning itself violates human morality, which is not only bad for human beings, but also bad for the whole society. Secondly, if the bill of human cloning is passed, what will this society become? The problem can be imagined. seven
7. With the development of science and technology, human beings have been liberated and computers have gradually become popular. Although it brings convenience to people, it also has many shortcomings. Humans become lazy, have no motivation to live, have redundant information and a lot of junk information. At the same time, personal privacy has nowhere to hide, and account passwords are leaked. ...
8. While developing science and technology, it is also destroying nature and bringing a lot of trouble and harm to mankind. The United States has developed science and technology, but there are still many problems left for them to solve. This is an invisible disaster, sometimes at the cost of human life.
9. The negative effects of biotechnology are mainly manifested in the following aspects: First, when people develop and use biotechnology, unexpected security problems may occur. Just as the environmental release of various genetically modified organisms is widely concerned about the harm to biodiversity. In addition, genetically engineered drugs, vaccines, genetically modified foods, gene therapy, etc. There may be similar problems. The misuse and unethical application of biotechnology may also bring great security risks. From the perspective of biosafety, the invasion of alien species and the loss of biological resources may cause great harm to national interests. The environmental release of genetically modified organisms poses a great threat to biodiversity.
10; The negative impact of the Internet on teenagers' ideological and moral quality is mainly reflected in the following aspects: the flood of online information may cause the lack of teenagers' beliefs or the diversification of values, which will affect the formation of teenagers' correct outlook on life and values; The concealment of network information reception and dissemination may lead to the weakening of teenagers' moral consciousness and the decline of social responsibility. Internet communication is hidden and unconstrained, and it is easy for teenagers to do some unconventional things and even embark on the road of crime.
