Another celebrity that I have come to love is Woody Harrelson. Woody isn't afraid to speak the truth, and I think anyone who is actively trying to educate others about living "greener" and more simply deserves respect. I first learned of his activism when I found the documentary "Go Further" on Netflix. The film shows Woody's bicycle trek down the West Coast. He makes stops along the way to educate students and anyone else who will listen about bio diesel, the sustainable uses of hemp, deforestation, raw foodism, and more. There are tons of "extras" on the DVD, including a little clip of Julia Butterfly Hill, whom I also admire. You can check out more of his work at his website, Voice Yourself. If you decide to watch the movie...you will also love the companion book, To Go Further: A Guide to Simple Organic Living. It's a favorite on my bookshelf.
