I think there is just a vein of humanity that really loves animals and really loves to read about them.

I just think I'm better equipped to make a study of human personality than trying to get into the mind of animals.

Gorillas are in danger of being wiped out by the Ebola virus. I feel like we have limited time to get to know them and understand them and they're going to disappear - that's terrifically sad. Wouldn't it be great if we could stop that?

Sometimes I panic and think I can't really write.

Sometimes I think I'm a one-trick pony because I'm not very inventive about new ways of telling stories.

We don't really think that much about what we do; it's just fun.
