David Suzuki, William Shatner, Patrick Stewart (ok lots of people from star trek), Vandana Shiva, Michaelle Jean (where is she, what is she gonna do?), alot of environmental philosophers and researchers, Jane Jacobs, the person that thought of the brilliant idea to make red licorice (yummy, I hope he got his fair cut), more fun-loving good people. Kristen Dunst and Christina Ricci for famous young actresses come to mind.
