I believe that we have more capability than any other creature to control our biological inheritance - and we do so most of the time.

I see that within each human being there are two extremes: there's the loving, the passionate, altruistic side that has evolved with us, and then there's the violent, brutal side that has evolved with us. The question for each individual is: which side is going to come out on top?

We are always talking about how we can get more environmental and humanitarian education. It is about listening to the voice of young people - how they feel, and what would be most meaningful for them.

Farm animals feel pleasure and sadness, excitement and resentment, depression, fear, and pain. They are far more aware and intelligent than we ever imagined...they are individuals in their own right.

There are good mothers and bad ones, but most of them are somewhere in-between.

Anyone who tries to improve the lives of animals invariably comes in for criticism from those who believe such efforts are misplaced in a world of suffering humanity.

I believe that accurate knowledge is very, very important, but find that out in free time. Don't let it take over every hour of the day. Perhaps most important, talk about it.
