Humanity across the 21st century, the world has undergone more or less amazing changes. In the people for the rapid development of science and technology to rejoice, but also experienced better uneasiness and even disaster. In addition to the panic brought about by the development of high technology, especially biotechnology, wars and diseases seem to bring mankind directly to the gates of hell.
The 2003 SARS epidemic, including all the speculation about SARS, is directly linked to a growing global concern: biosafety. Biosafety is a scientific and technological system of detection, evaluation, monitoring, prevention and management of biological hazards, is the study of various biological factors on human health, the application of existing theoretical knowledge, technology, engineering design and equipment, etc., to prevent personnel engaged in related work, laboratories and the environment from being potentially infectious substances and biotoxic substances of the hazards of an emerging fringe discipline. Biosecurity issues are manifested in at least the following aspects:
The great danger of infectious diseases
Infectious diseases, including human, animal and plant infectious diseases, especially human infectious diseases is the most important biosafety issues, infectious diseases are still the first cause of death in the world, in our country, infectious diseases are still a serious threat to the health of the people and national security. the SARS epidemic is a strong proof of this The SARS epidemic is a strong proof. In addition hepatitis, tuberculosis, influenza and other infectious diseases are still prevalent or outbreaks in some parts of the country and some countries and regions of the world every year
Potential Threats of Biological Weapons and Biological Terrorism
The entire international community has made unremitting efforts to prohibit biological weapons in the 20th century, and some progress has been made. However, in the 21st century, the potential threat of biological weapons has greatly increased, and some countries and regions may still continue to research and develop biological weapons. In addition, the rapid development of biotechnology has greatly increased the potential threat of biological weapons, and bioterrorism, symbolized by the U.S. anthrax incident, has posed a real threat to international security. The anthrax incident in the United States is a real threat to international security. Yuen Kwok-yung, head of the Department of Microbiology at the University of Hong Kong, was the first scholar to isolate a coronavirus and to discover that a variant of the coronavirus was the pathogen of SARS, an RNA virus that can easily recombine with other viral genes to become a new virus. Many experiments have shown that new viruses produced in this way are more virulent than their parent viruses. Coronaviruses can be found in many animals, and they can easily mutate, making them extremely dangerous. Yuan therefore believes that the SARS virus has great potential to become a pathogen for making biochemical weapons in addition to smallpox.
Technological development has brought convenience to people's lives ``
For example, cell phones, computers, and other devices that can facilitate the transfer of information, as well as many other things.
But while technological development has brought convenience, factories are constantly destroying the environment with the production of wastewater, waste gas, and waste products
And there is also the white pollution of plastics that will not decompose for 10,000 years in soil.
And because of environmental pollution, penguins have been found to have chemicals in their bodies at both poles of the Earth.
1 Environmental pollution. This is the most immediate and obvious bad thing.
2:Accelerated extinction of species. This is caused by environmental pollution and human killing. It is also the bad side of technological development.
3:The safety of human beings is getting more and more insecure. Nowadays, there are tens of thousands of crimes occurring every day. Most of these crimes are related to the latest technology. Gun crime, in particular, has become a major concern for the general public. As we have seen in World War II, with the advancement of technology, wars now cause far more damage and loss than ever before. It may even lead to the end of the human race.
4: The physical quality of human beings is not as good as before. With the development of science and technology, gas cars, trains, airplanes and other modes of transportation to make the human daily life has undergone a major change, human beings are no longer always rely on their own two legs, and therefore the physical quality of human beings and the previous compared to the physical quality of human beings has been incomparable. In the past, Xiang Yu's "power to pull mountains and rivers to cover the Ruoxi" is no longer possible in today's society. And this situation continues to develop is likely to make the human limbs atrophy, so that human beings appear a new form.
5: A variety of emerging germs continue to appear, many of which have far exceeded the destructive power of the previous germs. This is due to the rapid development of medical technology has accelerated the mutation of viruses. So much so, that technology is no longer able to keep up with the speed of virus mutation. Perhaps one day the human race will be destroyed by a major plague.
Lee: Science and technology are the weapons of mankind to overcome nature and transform nature, and are the important force to promote the development of social productivity. Every development of science and technology is a leap in the history of human civilization and an epoch-making victory for mankind to conquer nature and itself. In the primitive society and the early stage of slave society, it is because of the casting of bronze and the use of iron, which makes the social wealth grow exponentially, causing changes in the social form; in the 18th century, it is because of the wide application of steam engine technology, which makes the industrial revolution enter a new stage, thus doubling the wealth of the capitalist world; after the Second World War, it is due to the use of of electrical appliances as the mainstay of the third scientific and technological revolution, which greatly contributed to the economic recovery of the post-war capitalist countries and the substantial growth of the economies of the socialist countries, and to the rapid increase in the wealth of the society and the fundamental improvement in the lives of the people. Therefore, the favorable aspects of scientific and technological development are obvious.
Disadvantages: 1:Environmental pollution. This is the most direct and conspicuous bad. 2:Acceleration of species extinction. This is caused by environmental pollution and human hunting. Also belongs to the bad side of the development of science and technology. 3:The safety of human beings is getting more and more insecure. There are tens of thousands of crimes every day. Most of these crimes are committed with the latest technology. Gun crime, in particular, is a major threat to the general population. As we have seen in World War II, with the advancement of technology, wars now cause far more damage and loss than ever before. It may even cause the fate of the human race. 4:The physical quality of human beings is not as good as before. With the development of science and technology, gas cars, trains, airplanes and other means of transportation to make the human daily life has changed significantly, human beings are no longer always rely on their own two legs, and therefore the physical quality of human beings and the previous compared to the physical quality of human beings has been incomparable. In the past, Xiang Yu's "power to pull mountains and rivers to cover the Ruoxi" is no longer possible in today's society. And this situation continues to develop it is possible to make people's limbs atrophy, so that human beings appear a new form. 5: The emergence of new germs, many of which have far exceeded the destructive power of the previous germs. This is due to the fact that the rapid development of medical technology has accelerated the mutation of viruses. So much so, that technology is no longer able to keep up with the speed of virus mutation. Perhaps one day the human race will die in a major plague.
