Disadvantages of science and technology: when science and technology are not harmonious with the environment, it will cause environmental pollution; When technology is communicating with people, if the designer doesn't handle it well with you, it will appear very cold and impersonal; When technology and biology are not harmonious, there will be competition or even destruction of some opposing creatures ... in short, it depends on how users use them.

The development of high technology is always a double-edged sword, sometimes it will hurt you if you don't handle it well.

For example, the Chernobyl nuclear accident in that year, it was precisely because of this "high-tech" development that mankind was facing an increasing "suicide" crisis.

Why are people so concerned about the North Korean nuclear issue and the Iranian nuclear issue now? That's because once human morality can't keep up with the development of high technology, the high technology that should serve people becomes a reminder of killing people.

Many movies about the end of mankind say that the development of high technology will destroy mankind in the end. In fact, this assertion is not a fantasy.

Nowadays, human beings and high technology are like babies waving sledgehammers. It's hard to say when they will be hit by a hammer.

Example: We can cite more disasters caused by modern science and technology, such as photochemical smog in the United States and benzene pollution in Heilongjiang, China.
