More teens say social media makes them more aware of others' needs, study finds

According to a new 30 Hour Famine study, conducted online in January by Harris Interactive, more than half of teens (55 percent) say social media sites like Facebook and Twitter have made them more aware of the needs of others. This is a huge increase from 2011 when a little more four in 10 (44 percent) said their use of social media made them more aware. The study also says two in three teens (68 percent) agree that the benefits of social media outweigh the risks.
