What are the effects of the Internet on youth?

It's both a boon and a bane. Internet has helped man to see the other part of the world at the click of a mouse. We know what is happening everwhere- may it be any current affair, floods, earthquakes, politics, latest treatment, invention of electronic gadgets, astronomical discovery etc. Secondly, Internet has helped people to connect--emails for one-to-one interaction, blogs for expressing & discussing, groups for specialized discussion. Thirdly, it helps saving lives of people in several ways. Medical research, new drugs, organ donors, infertility treatments, unusual surgeries..we now are aware where we can go for treatment.Fourthly, business is totally dependent on internet. For any company, there are offices globally. Employees connect with each other, have video conferences, have meetings on internet.Sales and marketing is highly efficient because world is a global village. Fifth, online shopping is the in-thing now. It saves time, energy.Again, people from one part of the world can order anything from a distant place.There are many more miscellaneous benefits--tracking courier, online reservations, online examinations, online lecture classes.At the same time, internet has a long list of shortcomings too.Today there are websites which showcase pornography. Rapes, sexual abuse has increased. Kids at a very young age get exposed to things which they shouldn't be at their age. One can have multiple email addresses. People make fake addresses and misuse this independence. Kids keep on chatting with anonymous people the whole night. Their eyes are badly affected. Carpel Tunnel Syndrome is becoming too common. Medicine has now recongnized "addiction to internet" as a disease. I do not recollect the actual name given to this problem.
