You're thinking about putting scientists into small cages and doing research on them. I wish it could happen sometimes.

The most important thing is to actually think about what you do. To become aware and actually think about the effect of what you do on the environment and on society. That's key, and that underlies everything else.

It is these undeniable qualities of human love and compassion and self-sacrifice that give me hope for the future. We are, indeed, often cruel and evil. Nobody can deny this. We gang up on each one another, we torture each other, with words as well as deeds, we fight, we kill. But we are also capable of the most noble, generous, and heroic behavior.

Above all we must realize that each of us makes a difference with our life. Each of us impacts the world around us every single day. We have a choice to use the gift of our life to make the world a better place - or not to bother

Most Africans don't get to see these wild animals at all. Once they see and learn about them, they are much more likely to become involved in protecting the environment.

Nothing is more precious than your baby.
