learn to use internet

Can we say one of the best inventions's of mankind, the internet, is harmfull? Is it possible for people to only think in negative way? I think yes. There are some people strongly allege that internet is harmfull. The best way to change their mind is to take their chance to access interenet and then make them understand how the internet made their life easier. I don't think there are people who doesn't use internet. So, it is hard to understand why the don't like it but sttill use it.
People claim that internet is unhealthy. I admit if a person sit all the day in front of the computer it would be unhealthy. But this result is not because of internet's being a negative invention but because of this people's choise to use it this way. People tend to use invention's in a bad way. It doesn't mean the invention is bad. Because we use it in many aspects to ease our lives. you can do your shopping online, read your newspaper online, listen mucis, play game etc.
There is a group claims that internet is a obctacle for people communication. How something communicate people be an obstacle for communication? This belief again comes from the wrong usage of internet. When we use it in the right way, we can see it make the communication easier. When you meet your friend, email her, and tell where and when to meet, for example. Or, to inform your friend about the latest news chat with him on msn. When you are away and miss your friends, use skype to see them by camera. see how it helps to communication.
There are some people who thinks it is dangerous for children, but it is possible to limit the time children spent with internet, and avoid the children from some sites which are dangerous for them. Children can spend beneficial time on internet, playing some beneficial games to improve their creavity. And I think it is good for children to learn how to use computer and how to achive the required information earlier.
As you see, ofcourse it can see bad from an angle if you use it wrongly. But actually it is an important part of our lives. We should learn to use it more beneficially for it to help us.
