We are beginning to learn that each animal has a life and a place and a role in this world. If we place compassion and care in the middle of all our dealings with the animal world and honor and respect their lives, our attitudes will change.

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

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.

Without the heart to ground it and open it to who we really can be as human beings, the brain is a very dangerous machine. A machine that is saying: we've got to have economic growth; we've got to have unending economic growth, otherwise societies will collapse. And yet there should be something saying: wait a minute, this isn't going to work.

I think the most important thing to do is to be willing to listen, willing to care, and willing to admit mistakes and change your ways for the better!

Other people have talked about chimpanzees being a window into the past, which I suppose is true, in a way.

If you work hard and be persistent, you will achieve whatever you want to do.
