Change happens by listening and then starting a dialogue with the people who are doing something you don't believe is right. - Jane Goodall

Understanding what chimpanzees are like has made me realize that we humans are not so different from other animals as we used to think. What makes us most different is that we are far more clever than even the cleverest chimp, and we have words. We have a spoken language. We can tell stories about what happened a week or a year or a decade ago. We can plan for the future, and we can discuss things - one person's idea can grow and change as other people contribute their ideas. Great ideas become greater, problems are solved.

How would I have turned out, I sometimes wonder, had I grown up in a house that stifled enterprise by imposing harsh and senseless discipline? Or in an atmosphere of overindulgence, in a household where there were no rules, no boundaries drawn? My mother certainly understood the importance of discipline, but she always explained why some things were not allowed. Above all, she tried to be fair and to be consistent.

I do have hope. Nature is enormously resilient, humans are vastly intelligent, the energy and enthusiasm that can be kindled among young people seems without limit, and he human spirit is indomitable. But if we want life, we will have to stop depending on someone else to save the world. It is up to us-you and me, all of us. Myself, I have placed my faith in the children.
