Can Internet help the world to be a better place?

Last ten or fifteen years ago, new technologies (like Internet) have developed quickly. Today, using Internet you can talk and communicate with people who are a few kilometres away from you. However, can you use this technology to do the world a better place? 

Internet is a rather good place to realize campaigns to change our planet because this technology arrives to all the world. For example, people who disagree with pollution can use Internet to try that the rest of people change. Other examples are the Arabic Revolutions: these movements began in Twitter, where a lot of Egypt people talked about a Revolution against the old system.

Although a lot of people use Internet to do things like abuse of children or steal money. Things like these aren't definitely good for us and our planet. Besides, using Internet, we lose a lot of privacy: everybody can know your name, your address, your mobile phone etc. I think talk using Internet isn't so good for us because we lose human contact (face-to-face) and that's very important. 

In conclusion, we can use Internet to do the world a better place but we have to be alert with people who use this technology badly.
