The development of 1 sub-physics theory has not only enabled mankind to master nuclear energy technology, but also brought about the nuclear disasters in Hiroshima and Nagasaki, and brought about the "terrible peace" of mankind for 50 years. For the first time, mankind has the ability of self-destruction. In addition, there are endless nuclear accidents, among which Chernobyl in the Soviet Union is the most famous (please search online for specific data). The development of chemistry has given us unprecedented ability to transform nature, but our gunpowder and explosives have also hurt tens of millions of human compatriots. Our chemical synthesis technology has created things that do not exist in nature, but now we are also troubled by white garbage and poisoned by chemical pollution. Why are so many children suffering from leukemia in our country now? Very important factors are chemical adhesives used in home decoration and ozone-destroying freon. The development of petroleum exploration technology has greatly accelerated the pace of human progress. We have been able to fly faster than the speed of sound, but it has also brought too many wars and too much interference, and the earth began to catch a cold and have a fever. The development of biotechnology has given us the power to create life monopolized by God before, but it has also brought about ethical disorder. In short, scientific progress is always accompanied by corresponding drawbacks and dangers. Today, we must face up to these negative effects, otherwise we humans may eventually be destroyed in our own hands.
Personal safety is becoming more and more insecure. Now tens of thousands of crimes occur on average every day. Most of their criminal methods are related to new technologies. 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.
With the development of science and technology, the appearance of vehicles such as air cars, trains and airplanes has greatly changed the daily life of human beings. Humans no longer always rely on their own legs, so the physical quality of human beings can't be compared with before. It is impossible for Xiang Yu to "cover the sky with mountains and rivers" in today's society. If this situation continues to develop, it may make people's limbs atrophy and a new one appear.
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 die of a great plague.
With the acceleration of people's life rhythm and the improvement of living standards, the amount of plastic is increasing day by day. From 65438 to 0996, the consumption of plastic packaging in China reached 2.43 million tons, with an average annual growth rate of more than 20%, especially in the garbage of cities, main traffic arteries and tourist attractions. According to the survey, the annual output of domestic waste in Beijing has reached 3 million tons, of which waste plastics account for about 3%, with an annual growth rate of 48%. The content of plastic in garbage in coastal cities is higher, reaching 8- 10%. These wastes
If calculated by volume, the proportion of plastic in garbage has reached more than one third, which greatly increases the difficulty and cost of garbage disposal. Because waste plastics are difficult to degrade for hundreds of years, if discarded in the natural environment, it will provide a hotbed for mosquitoes, flies and bacteria to survive and reproduce; If buried underground, it is easy to pollute groundwater, hinder the growth of plant roots, destroy soil quality and affect crop harvest; If you burn with fire, it will produce a variety of toxic gases. "White pollution" has become a major public hazard to China's social environment, which has seriously hindered the sustainable development of China's economy and environment.
The development of science and technology is based on destruction and continuous summarization. Therefore, its development and further deepening will certainly bring some negative effects to the environment. Throughout the long history, with the development of science and technology, the damage will be more serious!
In today's society, cars can be seen everywhere, which not only does great harm to people's body and mind, but also pollutes the atmosphere. All living things in the world are infringed by this "scientific and technological product" to some extent. It is selfish for human beings to take care of the safety of other creatures on earth for their own convenience. To say the least, cars are also very harmful to human beings. Freon in air conditioners and refrigerators also destroys our precious atmosphere. The so-called high-tech products make the world dirty and rigid. The land of freedom is swallowed up bit by bit by human beings, the sky of freedom is shrunk bit by bit by human beings, and the ocean of freedom is occupied bit by bit by human beings.
At present, with the rapid development of biotechnology, biosafety has become a major proposition that affects the politics, economy, security and peace of the whole country and even the whole world. In recent years, especially after the "anthrax infection incident" in the United States, biosafety issues have attracted much attention at home and abroad, and biosafety terms often appear in government or non-governmental organization documents and in various media. The global epidemic of SARS will undoubtedly make countries around the world pay more attention to biological safety and regard it as an integral part of national security.
Compared with other physical and chemical laboratories or other laboratories, the Microbiology and Biomedical Laboratory is a special laboratory. Everyone who works in it and the surrounding environment in contact with it are high-risk people who are infected with infectious diseases or affect their health. Omissions and accidents in microbiology laboratory management will not only lead to infection of laboratory staff, but also cause environmental pollution and large-scale population infection. Accidents of accidental infection in laboratories at home and abroad are common. In serious cases, thousands of experimental animals have to be slaughtered, even leading to the death of laboratory staff.
10 When people develop and utilize 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. The study of somatic cell cloning is a prominent example.
1 1 Like any industrial products we use, air conditioning will inevitably bring a certain burden to our environment. A few years ago, the impact of air conditioning on nature mainly focused on the destruction of the ozone layer by refrigerants, but in recent years, due to the development of refrigerant renewal, this is no longer the main factor. The impact of air conditioning on nature in the future is still reflected in the field of energy consumption, which has accounted for a large proportion of the total energy consumption in our life and industry. The development of energy and the release of a large amount of heat to the atmospheric environment have caused a huge burden to our natural environment, which is the main problem we must solve for a long time.
12 challenges to ethics: so far, the issue of cloning has not seen any benefits to human beings, such as the benefits of treating diseases. On the contrary, the issue of cloning has brought great challenges to human ethics; There is also harm to human security: technology is accompanied by high risks, and large-scale tragedies often occur in the development of science and technology, such as Hiroshima atomic bomb and Chernobyl nuclear leakage.
13 Disadvantages from scientific development to globalization and from globalization to globalization, such as cultural loss and cultural aggression under economic strength; From globalization to the change of ideas, it is best to give some examples, such as the lost generation in the United States, which consumes a lot of limited material resources on the earth; Some modern scientific products will be harmful to human health.
