2011 Ultimate Game Changer in Green and "Vampire Diaries" star Ian Somerhalder does more than glower at the screen and revel in his teen heartthrob status. This Louisiana native is passionate about the environment. Somerhalder was active in the cleanup efforts in the Gulf after the 2010 oil spill, speaking out in PSAs, raising money for animal shelters and local communities on his birthday, and testifying before congress about the H.R. 50, the Multinational Species Conservation Funds Reauthorization Act. This year, he also started the Ian Somerhalder Foundation, an ambitious effort with many areas of focus that include educating kids about the environment, funding global conservation efforts, and greening the entertainment industry.
