One individual cannot possible make a difference, alone. It is individual efforts, collectively, that makes a noticeable difference - all the difference in the world!

As a child, we couldn't afford holidays overseas, so instead I travelled through books. I was inspired by Dr Dolittle and Tarzan.

Whales, like elephants, are so social and intelligent. This hurts me to think of them being transported, put in noisy airplanes, and brought to a horrible concrete pen when they're supposed to be out in the sea.

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.

Chimps are far too much human to be my favorite animal.

We have turned away from the natural world. Instead, it's all about money and power.

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.
