I'm always pushing for human responsibility. Given that chimpanzees and many other animals are sentient and sapient, then we should treat them with respect.

Studying chimps, I came to the conclusion that being evil is something that only humans are capable of. A chimp would never plan to pull another's nails out. The chimps' way of aggression is quick and brutal. I compare them to gang attacks.

I like some animals more than some people, some people more than some animals.

I want to change awareness.

If everybody on the planet today had the same standard of living as the average European or American, we would need three new planets. But we don't even have one new planet. We have this one, and with the way we're polluting it, the shrinking water resources, the climate change, the experimentation with plants... the outlook is grim.

I believe the only hope for mankind lies in the hands of our young people.

To me, cruelty is the worst of human sins. Once we accept that a living creature has feelings and suffers pain, then by knowingly and deliberately inflicting suffering on that creature, we are guilty, whether it be human or animal.
