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.
