Television is indispensable in life. We can watch the news and learn about things at home and abroad; You can watch cartoons and relax; You can also not go to the scene to watch programs and performances; For example, when the Olympic mascots are announced, you can watch the broadcast at home.

Computers are more and more widely used in all walks of life. We sent a letter to Brazil in Haining, and it only took a few seconds for the other party to receive it. We can chat and play games with friends and relatives all over the world online. You can watch news, movies and listen to music online. You can listen to the teacher in class, find information, shop at home, have medical treatment and give first aid. ...

Science and technology have deeply influenced our daily life and played an indispensable role in economic and social development. Especially since the 20th century, with the rapid development of science and technology, especially computer network technology and electronic information technology, expensive luxuries such as mobile phones and computers have entered the homes of ordinary people and become necessities of our lives.

Of course, the development of science and technology has also caused some negative effects, but these effects should have been very small, but human beings are like a magnifying glass, magnifying these negative effects. If humans can consciously reuse plastic bags instead of littering them, will it cause such serious white pollution? If mankind can exploit resources exhaustively, will it cause the current shortage of resources? If humans can save water, factories will not illegally discharge sewage.

1: Environmental pollution. This is the most direct and obvious disadvantage.

2. Species extinction is accelerating. This is caused by environmental pollution and human hunting. It also belongs to the disadvantages of scientific and technological development.

3. Personal safety is increasingly insecure. Now tens of thousands of crimes occur on average every day. Most of their criminal methods are related to the current new technology. Especially gun-related crimes, ordinary people can't prevent them. 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 comparable. It may even lead to the fate of human extinction.

Human's physical quality 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 greatly changed human daily life. Human beings are no longer always dependent on their own legs, so the physical quality of human beings is not comparable to that in the past. In today's society, it is impossible for Xiang Yu to "pull out mountains and rivers". If this situation continues to develop, it may make people's limbs atrophy and make people appear.

5. 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 die of a great plague. With the development of economy, the acceleration of people's life rhythm and the improvement of living standards, the amount of plastic used by each newcomer is increasing day by day. From 65438 to 0996, the consumption of plastic packaging in China reached 2.43 million tons, with an average annual growth rate of more than 20%, especially in the garbage of cities, main traffic arteries and tourist attractions. According to the survey, the annual output of domestic waste in Beijing has reached 3 million tons, of which waste plastics account for about 3%, increasing year by year.

The growth rate reached 48%. The content of plastic in garbage in coastal cities is higher, reaching 8- 10%. The volume ratio of these waste plastics in garbage is more than one third, which greatly increases the difficulty and cost of garbage disposal.
