"I often think about what the chimpanzees would say if they could talk. I think they'd tell us to be kinder to each other, and to the planet."

"I think the best evenings are when we have messages from the animal world."

"The greatest lesson I learned from the chimpanzees is that we are not so different from them."

"We are, indeed, often cruel and evil. Nobody can deny this. We gang up on one another, we torture each other, we use our intellect to manipulate, we kill."

"The greatest threat to our survival is the destruction of the natural world."
