'Vampire Diaries' star Ian Somerhalder joins Gisele Bundchen and Don Cheadle for UN Environment Program

ian-somerhalder-UN-ambassador.jpgAs if "Vampire Diaries" star Ian Somerhalder didn't have enough on his plate between saving the world with the Ian Somerhalder Foundation off-screen and wooing Elena on-screen, he's now taken on a new title as a United Nations ambassador for their upcoming World Environment Day.

Last year, Gisele Bundchen and Don Cheadle joined forces to encourage people to contribute to clean-up progress and environmental causes on a specific day, registering their activities in order to break a record. Somerhalder jokes that he joined in this year because he "couldn't decide between Team Don and Team Gisele."

"So as the new kid on the block, I am relieved that this year, we're all working together," he says. Check out the video below to learn more about the initiative -- and about how you can win one of five cars (fuel-efficient, of course!) that will be given to winners.

"Who knew being an environmental warrior could be so cool?" Somerhalder asks.
