The same mobile and online technology people use to meet up with friends is now being used to get America's young adults involved in the fight to save the environment. NRDC is reaching out to the group most inclined to use emerging technology -- 18- to 34-year-olds -- in the same ways they reach out to one another: via text messages, e-mail, and online social networking. NRDC now has a presence on MySpace (for social networking), YouTube (for videos), and Flickr (for photos). NRDC's generation-Y staffers are going to the places where their peers hang out, such as Tennessee's Bonnaroo Music and Arts Festival, to talk face-to-face about their future.
