Cameron Diaz was going green long before she took on the role of Princess Fiona in “Shrek.” This sexy superstar has proved time and again that she’s willing to get ugly to make her voice heard. Now she’s taking on her biggest role yet: environmental champion.

According to Cameron’s green biography on http://therenewableplanet.com, there is more to this Prius-driving girl-next-door than what meets the eye. Besides taking on leading roles in blockbusters, Cameron is involved in projects such as the MTV show “Trippin” where she traveled the world and learned how to protect the environment. She’s also the mastermind behind and appears in a documentary she traveled across the country to film. She came face-to-face with everyday people to help them change their habits to be more eco-friendly. Cameron is also one of the many stars who contributed tips on living ecologically to “The Green Book.” She wants the world to know that change can happen in the smallest of ways, like changing one lightbulb at home.
