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.

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.

It's the bond between mother and child, which is really for us and for chimps and other primates, the root of all the expressions of social behavior.

Surely it should be a matter of moral responsibility that we humans, different from other animals mainly by virtue of our more highly developed intellect and, with it, our greater capacity for understanding and compassion, ensure that medical progress slowly detaches its roots from the manure of non-human animal suffering and despair.

Here we are, arguably the most intelligent being that's ever walked planet Earth, with this extraordinary brain ... and yet we're destroying the only home we have.

I urge you to read Eternal Treblinka and think deeply about its important message.

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