Times have surely changed. The world has been made flat by the World Wide Web. Today, we live in a world where contacting someone, sharing our journeys as well as our thoughts is just one click away. Social networking sites are now available to cater to one’s immediate social needs. These networking sites have made it possible for us to chat with friends who live in distant places as well as share with them pictures and videos of whatever we are up to instantly. Today, it is very hard to find a teenager who doesn’t have a Yahoo, a Gmail, a Facebook, or a Twitter account which they use to keep in touch with friends, to express or share what they have in mind and to use for school-related purposes. No doubt, Social Networking Sites are of great help in the youth’s daily life; however, it has positive and negative effects which depend on how a person will utilize it. The negative effects of these social networking sites overweigh the positive ones. These sites have caused some potential harm to society. The students become victims of social networks more often than anyone else. This is because of the reason that when they are studying or searching their course material online, they get attracted to these sites to kill the boredom in their study time, diverting their attention from their work. The overuse of these sites on a daily basis has many negative effects on the physical and mental health of students making them lethargic and unmotivated to create contact with the people in person.
