Well, in some ways we're not successful at all. We're destroying our home. That's not a bit successful.

At some point, my body will collapse. But I hope that my brain will still be working so that I can carry on with writing.

From my perspective, I absolutely believe in a greater spiritual power, far greater than I am, from which I have derived strength in moments of sadness or fear. That's what I believe, and it was very, very strong in the forest.

Primates are very territorial. It is in their nature to protect their food resources as well as their females and young.

Chimpanzees, gorillas, orangutan shave been living for hundreds of thousands of years in their forest,living fantastic lives, never overpopulating, never destroying the forest. I would say that they have been in a way more successful than us as far as being in harmony with the environment.

Terrorism is usually fueled by poverty, and the fanatical faith of the terrorists who truly believe that the more people they kill who do not subscribe to their faith, the greater their reward in heaven.

Language allows us to talk about the past and plan the future. We can teach children about things that are not present. And above all, we can bring people with different backgrounds and different knowledge together to discuss our problems. This actually gives me hope. I still think we are smart enough to not destroy planet Earth, our only home.
