There are many people around the world who are against the сommunication in the Internet but there are some of them who support it.I think that nowadays the communication in the Internet can be really helpful for teenagers.
Firstly, it is a wonderful method of socialization and the way of getting rid of the loneliness. Secondly, it's an illusion of one's usefulness in the world. Thirdly, this way of communication is needed for some adolescents with disabilities.
But there are ones who don't think this communication is good. They are afraid that teenagers health can be spoilt by the Internet. They also suppose people can have some problems with communication in the real life.
I disagree with these people as our computers are really good now and cannot harm us. I also don't believe this communication affects on one's mind and skills.
On these basis, I can conclude that the Internet communication have more advantages that disadvantages.
