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.

You're thinking about putting scientists into small cages and doing research on them. I wish it could happen sometimes.

The greatest danger to our future is apathy.

We could change the world tomorrow if all the millions of people around the world acted the way they believe.

You better not mess with chimps. They are much stronger than humans.

But does that mean that war and violence are inevitable? I would argue not because we have also evolved this amazingly sophisticated intellect, and we are capable of controlling our innate behavior a lot of the time.

I had a wonderful teacher about animal behavior - my dog Rusty. He taught me that animals have personalities, minds, and feelings.
