Cameron Diaz graced the cover of "Marie Claire" this month to promote her upcoming film "My Sister's Keeper," but spent more time discussing her commitment to the environment:
"It's the planet, you know what I mean? She should be the one--she should be a star. How do we make this little planet of ours a big star? I want everybody to know who she is."
For the cover story, Diaz invited "Marie Claire" staffers to travel around the country with her while she worked on her documentary about what environmental worries plague Americans the most. The result is a short and sweet video in which Diaz questions everyone from a man in supermarket parking lot to a White House special advisor about their hopes and fears for the planet.
