Hayden Panettiere

A teen queen she may be, but the star of the hit show Heroes is already making quite a name for herself as an environmental and animal activist. Panettiere made international news when she was issued an arrest warrant in Japan after protesting against whale and dolphin hunting in that country. She was subsequently given a a Genesis Award (which honors those in the entertainment industry who help spread the message of compassion for animals) by the Humane Society for her efforts. A few months later, she was back in action on behalf of animals, donating the clothes off her back to raise money and awareness for the Save the Whales Again Campaign. She's also been snapped by the paparazzi carrying reusable grocery bags-to her SUV, though, proving she still has some green lessons to learn.
