Now is the time to divest and invest to let our world leaders know that we, as individuals and institutions, are taking action to address climate change, and we expect them to do their part this December in Paris at the U.N. climate talks.

When I was doing 'This Boy's Life' I wanted to be as old as Robert DeNiro and as experienced as him and have the same respect as he did in that movie.

Mother Earth is hurting. And she needs a generation of thoughtful, caring and active kids like all of you to protect her for the future.

I've managed to keep a clear head and remain sane in this business because I remain a kid off-camera.

I think actors make the mistake of finding their little niche in the business and once they try to do something a little darker, boom, they get slapped across the face for it, so they go back to what they did before.

When I was very young, biology, the diversity of life, was one of my main interests. I know there's this image people have that I'm this spoiled, cocky punk of an actor. Honestly, that's not who I am. I really care that so many species have been wiped out, like genocide of entire races. I believe in the divine right of all species to survive on this planet. So I decided I want to be active as an environmentalist. I learned. I asked experts. I got active.

If you're gonna let the character be the story, you better set a tone that allows the actors to do the best work they can do.
