Just think of the trust that often exists in soldiers. Within their own unit, you could say they have to trust each other. A spirit of camaraderie builds up and, in the end, they will risk their lives for each other. They may even go so far as to dehumanise the other, enemy group - a mechanism you can also observe in chimps.

Empathy is really important.. Only when our clever brain and our human heart work together in harmony can we achieve our full potential.

To reconnect with nature is key if we want to save the planet.

If harsher laws are put in place, less will dare to break them.

Lasting change is a series of compromises.

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 are incredibly intelligent. They can learn more than 400 signs of American Sign Language. They have memories for spatial distribution, like numbers on a TV screen, way better than ours. You come onto the emotions: happiness, sadness, fear, and despair - all the things for which I was accused of being anthropomorphic when I ascribed them to chimpanzees.
