Some humans are mathematicians-others aren't.

Chimpanzees can be quite political.

When you meet these outstanding leaders who have been through a programme that empowers them to take positive action, to make things better for people, for animals and for the environment - when you watch them interact and they start brainstorming, you realise you can relax, because they have got it right. They understand that there's more to this life than just money.

Chimpanzees, more than any other living creature, have helped us to understand that there is no sharp line between humans and the rest of the animal kingdom. It's a very blurry line, and it's getting more blurry all the time.

We, as humans, have actually developed a sense of social responsibility. We have gone beyond our basic instincts.

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?

The voice of the natural world would be, "Could you please give us space and leave us alone to get along with our own lives and our own ways, because we actually know much better how to do it then when you start interfering."
