TreeHugger Star Search: Rosario Dawson

Rosario Dawson's success story is even sweeter knowing she uses her fame to raise awareness for good environmental and social causes. Dawson, who was 'discovered' on her apartment building porch at age 15, has starred in hits Men in Black II, Sin City, and Rent. When she isn't on the silver screen, the actress is a spokesperson for the Lower Eastside Girls Club of New York — an organization that addresses literacy and leadership issues. Says Dawson, "You want to give these latchkey kids not just a place to hang out but get them engaged and involved and help them start thinking about college"

Back in '05 we reported that Dawson attended a UN conference in support of the Poverty-Environment Partnership — a network of organizations that promote preserving the environment as a means to end poverty.

Recently she's been paling around with eco-style guru Danny Seo. Says Dawson about Seo, "He's fun, he's smart, and he makes it seem so uncool not to think about the Earth." She's also styling it up green when choosing pieces for her wardrobe - word on the street is that Dawson dons eco-fashionable clothing line Stewart + Brown.

In March, the eco-activist joined fellow celebs Josh Hartnet and Jason Flemyg for the Global Cool text messaging campaign. For just a few bucks a month, fans can get eco-tip text messages from Dawson, with the proceeds supporting the Global Cool Foundation.
