Advantages and disadvantages of internet

Internet is something which often helps us in live. It has a lot of advantages and disadvantages, but I think that positive sides of Internet are more then negative.
The first advantage of using the internet is helping people in education. It’s a source of useful information which is needful in school or in live. We’ve got the access to information about different travel agency so we can find interesting offer on holiday etc. The Internet helps us in searching a job, choose the best school or we can learn foreign language. There are many adverts. We don’t have to sit long time in library because in the Internet are dictionaries, encyclopedias and education programs.
In the internet we can pay rachunki or buy different things without leaving home.
Through the Internet we can contact with people from every countries. It helps shy people to talk with other. It’s also the entertainment. We can play games, read funny texts, listen to Internet radio etc.
The disadvantages are less, but not any. Some people are addicted to Internet and they fail their families, health of people gets worst (spine, eyes). On chat sites there are many cheats and deviants. Sometimes we can’t believe with who we are talking. There are also demoralizing websites. People stops to read books or think independently because everything is on websites.
I think that the internet helps in live, and it’s good, but sometimes it can go for wrong way. People should use Internet with deliberation.
