Dawson's Green Credentials
Sin City star Rosario Dawson is so concerned about the environment, she would refuse to date a man who wasn't green-minded.
The Hollywood actress is so used to reducing her carbon footprint that she would only go out with a man who appreciates the dangers of climate change.
She says, "(I'm) that person who turns off the light every time I walk out of a room... I'd probably have a really huge problem with that (dating someone who isn't green)."
