Language allows us to talk about the past and plan the future. We can teach children about things that are not present. And above all, we can bring people with different backgrounds and different knowledge together to discuss our problems. This actually gives me hope. I still think we are smart enough to not destroy planet Earth, our only home.

It's the bond between mother and child, which is really, for us and for chimps and other primates, the root of all the expressions of social behavior.

Terrorism is fueled by hate. The tragedy is that there are countless young children who are being taught to hate. Terrorism is usually fueled also by poverty.

If we allow the destruction of the environment, we can see the terrorists have utterly won, and are destroying the future of our children and grandchildren. We must not let that happen.

You aren't going to save the world on your own. But you might inspire a generation of kids to save it for all of us. You would be amazed at what inspired children can do.
