The most important thing is not to list the disadvantages brought by technology to human beings, because if your eyes only focus on the disadvantages, then the other party is likely to seize the attack.

The progress of medical treatment and the backwardness of people's physique

Reduce people's adaptability to the natural environment and reduce immunity.

nature

Nature and technology can bring technology, but technology can't save nature.

The nature destroyed by science and technology is inversely proportional to the nature restored.

The data show that about 65.438+0.2 million years ago, 6.2 billion hectares of forest covered nearly 65.438+0/2 of the land, and now there are only more than 2 billion hectares left. The global tropical rain forest is decreasing at a rate of 6.5438+0.7 million hectares per year, which means that we are losing a tropical rain forest the size of a football field every minute.

Every year, the global production and consumption of paper has reached 320 million tons. If four trees with an average age of 20 years are cut down from each ton of paper, nearly 1 300 million such trees will disappear from the earth after1year.

Historically, forests once covered 2/3 of the earth's land area. After entering the 20th century, the rate of forest reduction has further accelerated. If this development continues, tropical forest resources all over the world may be destroyed in a few years.

At present, about 8700 species are extinct every year, and one species is extinct every hour on average. Faster than natural extinction 1000 times.
