The 21st century is marked by the Internet revolution and the coming arrival of computers, a variety of kids are addicted to them. However, allowing your kids to access the Internet without any parental supervision will result in potential risk. The following essay will discuss.

    Firstly, I want to tell you some disadvantages of the Internet that can be harmful to children's health especially their eyes. If they spend too much time using the internet, their eyes will be hurt.
Moreover, one of the purposes they usually access the internet without supervision is playing games online. There are many kinds of games that players have to pay real money to buy a VIP account or card. However, children don't have the ability to buy them. So they try to steal money from their parents to satisfy their own needs. That is the way they are easily pretended to do wrong things.

    Secondly, the adolescents who are superficial may not listen to their parents and keep on associate with strangers. So the strangers can know their personal information such as profile, schedule,... Strangers can take advantage of you or they sell your information to somebody else. In addition, on the Internet is many kidnappers and bad people. 

    The last disadvantage of using the internet without parents' supervision is the websites with bad content for children's age. There are is so much information on the internet that parents have to control them. Because children maybe can meet some violent, reactive and depraved contents. Therefore, children have to realize their actions and the extreme disadvantage of the internet. Nurturing children in reasonable ways contributes to the development of society and country.

    To conclude, the Internet is a double-edged sword. It is really becoming serious little by little. Parents and teachers must take the lead in dealing with this problem, otherwise, a whole lot of young lives will get disturbed. Children are like clean paper, they can be impacted by what they see.
