Environmental pollution is the most direct and obvious disadvantage, and species extinction is accelerating. This is caused by environmental pollution and human hunting, and it also belongs to the disadvantage of scientific and technological development.
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 has not kept up with the mutation speed of virus. Maybe one day mankind will perish in a great plague, and so on. ...
For example, in our daily life, we often use computers, but some people don't make good use of computers, which leads to the failure of all social talents in the hands of computers. Myopia, addiction, addiction, will affect learning, will affect people's future, and will be a great loss to tomorrow's society! In the news, we can see that some people are addicted to computer games, which leads to partners killing people in the street! After they were arrested, it was too late. ...
Besides computers, things like TV can also cause people's myopia. If they are nearsighted, they can't see clearly. If they lose their glasses and can't find them, the consequences can be imagined. Myopia will hurt their eyes, and in severe cases, it will lead to blindness, and they will become disabled. Should we just stand by and watch? So the development of science and technology is harmful!
The invention of plastic bags is also the development of science and technology, which brings white pollution and cannot be decomposed, causing pollution to the environment. The details are as follows: The recycling value of plastic bags is low. In the process of use, plastic bags are not only scattered on urban streets, tourist areas, water bodies, highways and railways, causing "visual pollution" pollution, but also potentially harmful. Plastic has a stable structure and is not easily degraded by natural microorganisms. Will not separate in the natural environment for a long time. This means that if the waste plastic waste is not recycled, it will become a pollutant in the environment forever and accumulate continuously, causing great harm to the environment. The accumulation of waste plastic products mixed in soil will affect the absorption of nutrients and water by crops, resulting in crop yield reduction.
