With just a day left until the 83rd Annual Academy Awards take place on February 27th, oscar predictions run rampant. Even a cross-eyed opossum is throwing in her two cents. We at HuffPost Green want to honor those nominees who have not only contributed positively to a film, but have also contributed positively to the environment.

From actors like Natalie Portman who embraces a vegan lifestyle while sporting an eco-friendly engagement ring, to directors like Darren Aronokfsy who banned plastic water bottles from his set, this is a tight race as well. Although in our eyes, all of these nominated environmentalists are winners.
