The chimpanzees taught me a lot about nonverbal communication. The big difference between them and us is that they don't have spoken language. Everything else is almost the same: Kissing, embracing, swaggering, shaking the fist.

The least I can do is speak out for the hundreds of chimpanzees who, right now, sit hunched, miserable and without hope, staring out with dead eyes from their metal prisons. They cannot speak for themselves.

We are unique. Chimpanzees are unique. Dogs are unique. But we humans are just not as different as we used to think.

I think we must cling to the hope that we can see in the great heroism, the bravery of the firemen and policemen, and the outpouring of caring and concern that has come pouring in from around the world.

Here we are, the most clever species ever to have lived. So how is it we can destroy the only planet we have?

If you catch somebody doing something wrong, he will just cringe away and curl up. He will not listen anymore. Instead, he will think of how he can counterattack.

Someday we shall look back on this dark era of agriculture and shake our heads. How could we have ever believed that it was a good idea to grow our food with poisons?
