When hearing about yet another Hollywood starlet doing this or that to ‘save the environment’, the skeptic within might assume it’s just another paparazzi ploy. But California girl Sophia Bush – who achieved mainstream fame thanks to her role in the CW’s One Tree Hill – appears to be the real deal (and not only because she’s looney for recycling).

Bush was so “enraged” by what she saw during her tour of the post-Gulf spill devastation with Global Green USA (video below) that she was inspired to make a difference. Despite being asthmatic and harboring “a years-old knee injury”, Bush plans to run a 13.1 half marathon this November in order to raise cash for BP oil spill victims (a nod to Norton and his wildly successful fundraising efforts on behalf of the Maasai during the 2009 NYC Marathon). She’s even using the newly appointed UN Goodwill Ambassador For Biodiversity’s social fundraising website Crowdrise to do it.

Take one look at her personal page on Crowdrise and you’ll realize that while her heart is in the Gulf, she’s busy promoting other projects, too, like Global Green USA, a special meditation program by director David Lynch to benefit at-risk youth and Glen Hansard’s ‘Maasai Villagers Need A Truck’ project (the very same one we reported on earlier this week).

In the blur of celebrity news out there, it’s a pleasure to keep Ecorazzi readers up-to-date on the philanthropic actions of those who really make the most of their high profile status. Sophia, way to go!
