"Chimpanzees, more than any other living creature, have helped us to understand that there is no sharp line dividing humans from the rest of the animal kingdom."

"We have so far to go to understand the minds of the other animals, and how much they suffer."

"Every single one of us can make a difference, and we should never forget that."

"You cannot get through a single day without having an impact on the world around you. What you do makes a difference, and you have to decide what kind of difference you want to make."

"When I was a little girl, I used to pretend I was Tarzan. I would climb trees and talk to the animals."
