To reconnect with nature is key if we want to save the planet.

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

We have language and they do not. Chimps communicate by embracing, patting, looking - all these things. And they have lots of sounds. But they cannot sit and discuss. They cannot teach about things that are not present, as far as we know.

Having respect for animals makes us better humans.

The more we learn of the true nature of non-human animals, especially those with complex brains and corresponding complex social behavior, the more ethical concerns are raised regarding their use in the service of man - whether this be in entertainment, as "pets," for food, in research laboratories, or any of the other uses to which we subject them.

War had always seemed to me to be a purely human behavior. Accounts of warlike behavior date back to the very first written records of human history; it seemed to be an almost universal characteristic of human groups.

The best relationship you can have with a chimpanzee is total mutual trust.
