Every invention has it's own advantages and disadvantages. You might be thinking that our society has improved after the discovery of internet. But that is not correct in all fields...
Humans were very creative and inventive before the invention of Internet. The aftermath leads to something like this -
1) Children of all age groups are being attracted towards electronic gadgets such as iPads, iPhones and smartphones.
2) Loss of creativity is taking place as every single idea is taken from the internet.
3) Where ever you look, children are busy chatting with someone or logging themselves into social networking sites such as Facebook, Twitter or Orkut.
4) Conversations with others are not taking place anymore because every question's answer can be found on the Internet. So there is no need to ask others.
5) Children, especially girls, are very active on social networking sites. They might be chatting with someone dangerous in the form of a little girl.
6) Internet also plays a huge part in the base of bad ideas. The creative and evil ideas terrorists get are mostly from the internet.
