What are the advantages and disadvantages of science?

First of all, it promotes social progress and human progress. For example, the invention and improvement of the steam engine in the first industrial revolution pushed mankind to age of steam, and the social productive forces developed greatly. The application of electricity in the second industrial revolution made mankind enter.

The invention and application of electronic computers and the application of information technology in the third scientific and technological revolution in the electronic age have brought mankind into the information age. etc

Second, promote people's mode of production, lifestyle and way of thinking. It promotes the development of productive forces, improves people's material and spiritual living conditions and improves people's quality of life. Accelerate the pace of social life and change people's ways of work and rest, communication, study, consumption and entertainment. Bring us into the information age. It provides us with the means to process, store and transmit information, and brings convenience to study and work. Modern transportation, communication and other means make the earth smaller, and people communicate conveniently and quickly. At the same time, it will promote the development of the tertiary industry and the socialization of family functions, and part of the early education and housework originally undertaken by the family will be separated and undertaken by the society.

The application of computers enables human beings to engage in spiritual production and creative activities in science, art, culture and education instead of the production of material materials needed by human beings. With the improvement of labor productivity, people can develop in an all-round way and move towards the highest ideal!

The telephone facilitates our communication, especially the mobile phone, which allows us to communicate anytime and anywhere.

Disadvantages:

First, it consumes a lot of resources, intensifies the pressure of resource shortage, destroys ecology and environment, and brings air pollution to mankind. These are the most direct and obvious disadvantages. Second, species extinction is accelerating, which is caused by environmental pollution and human hunting, and also belongs to the disadvantages of scientific and technological development.

Third, personal safety is increasingly insecure. Now there are tens of thousands of crimes every day on average, and their criminal methods are related to the new technology in Otawa, especially gun crimes, which make ordinary people hard to prevent. 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 being comparable, and may even lead to the fate of human extinction. Fourth, people's physical fitness 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 brought great changes to human daily life. Humans no longer always rely on their own legs, so the physical quality of human beings can't be compared with before.

Fifth, 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 variation of virus, so that the development speed of science and technology can't keep up with the speed of virus species, and maybe one day mankind will perish in a great plague.
