You may know Woody Harrelson for his Emmy-winning television work, his Oscar-nominated film roles, or as this year’s official sexiest celebrity vegetarian (thank you, PETA). Which is all fine and good, but we know (and admire and adore) Woody Harrelson for the love he shows the trees. Like some Lorax of Hollywood minus the “shortish and oldish and brownish and mossy” Harrelson speaks for the trees. And not only does he speak for them, he has been actively working on formidable solutions for ways to save the arboreal denizens of this orb we call home.
