I believe that the Internet is useful for us because in it you can find answers to many questions. You can communicate without leaving home, call and even see, because not everyone can afford a trip to another city or country. in the Internet we can learn self-education. But the Internet has and cons. Many people have them dependent. they do not face the street. cease to communicate with people. There are problems with health. And in the Internet there are so harmful information. Children are immersed in the Internet from an early age and in the future they suffer from psychological problems.
