Protect teenager from internet harms

In the past years, the technology has been developed rapidly. We can easily get access to the internet that gives us unlimited information from all over the world. It is now accessible, not only from the computer, but from the smart phone as well. So many people are using smart phone where you have access to everything wherever you go.
Although it seems very convenient and makes our life easier, there are some hidden issues underneath. Internet contains not only educational and positive information, but it also includes negative information such as sexual contents, violent contents, moral hazards and so forth. People are literally exposed to these problems without even realizing it. These are very dangerous, especially for teenagers. They are very curious about everything and it might bring negative impacts on them. Since their values and concepts of life are not fully developed, the teenagers might get wrong ideas of it off from the internet.
I believe that we need to protect teenagers from those harms, and it is important that we set up regulation measure on internet. In general, not many parents know how to use computer better than their children. For that reason, educating internet safety to teenagers is a countermeasure. If they do not understand the significance of it and not feel responsible, they will do it because it is lots of fun. In addition to exposure, teenagers also can communicate with other people online. Since they can write anything they want anonymous, some of them tend to write things that are not appropriate. This is also a reason why teaching them internet etiquette is important.
Most of the teenagers are literally immature. Like we discussed in class, their brain is still developing. They do things because it looks cool and it is lots of fun. They sometimes do not realize what is wrong, harmful, wasteful, or useful and it is our duty to guide them to the right path.
