Chimpanzees have given me so much. The long hours spent with them in the forest have enriched my life beyond measure. What I have learned from them has shaped my understanding of human behavior, of our place in nature.

It was because the chimps are so eye-catching, so like us and teach us so much that my work was recognised worldwide.

Become as knowledgeable as possible.

I always loved animals. And when I was ten, I decided I had to go to Africa and live with animals and write books about them.

I believe that the tragedy [like terror attack] that's caused so much grief and suffering to so many thousands and thousands of people has also served as a call to action, because many people now are re-examining their own value systems, and the churches, temples, mosques and cathedrals are packed to overflowing for the first time in years.

We can't leave people in abject poverty, so we need to raise the standard of living for 80% of the world's people, while bringing it down considerably for the 20% who are destroying our natural resources.

Animals are as deserving of a place on this planet as we are, and the difference between us is that humans have a voice they can use to help the animal cause, and it is up to all of us to use it to make a positive difference!
