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.

I feel a moral obligation to speak out at this key moment in human history - it is a moment for action.

As far as my own dreams, I'm not a big dreamer, I think obviously we suppress things in life, emotions and thoughts, and we should wake up and look at that.

It's not just global warming, it's not just a loss of biodiversity, it's not just the pollution of our oceans and the clearing of our rainforests and all these complicated systems, The [11th Hour] movie talks about the world economy, it talks about politics, it talks about personal transformation and environmental consciousness that we need to have in this generation to implement a lot of these changes that need to occur.

It's a weird feeling when people are defining you, and you haven't even defined yourself.

Honored delegates, leaders of the world, I pretend for a living.

You can make history, or you will be vilified by it.
