“Only if we understand, will we care. Only if we care, will we help. Only if we help, shall all be saved.”

Trees are living beings. And they have their own personalities. There are the young, eager saplings, all striving with each other. If you put your cheek against one of those, you almost sense the sap rising and the energy.

What you do makes a difference, and you have to decide what kind of difference you want to make.

From the moment when, staring into the eyes of a chimpanzee, I saw a thinking, reasoning personality looking back.

Each one of us matters, has a role to play, and makes a difference. Each one of us must take responsibility for our own lives, and above all, show respect and love for living things around us, especially each other.

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.

I like some animals more than some people, some people more than some animals.

Thousands of people who say they ‘love’ animals sit down once or twice a day to enjoy the flesh of creatures who have been utterly deprived of everything that could make their lives worth living and who endured the awful suffering and the terrors of the abattoirs

Change happens by listening and then starting a dialogue with the people who are doing something you don’t believe is right.

The least I can do is speak out for those who cannot speak for themselves

There is a powerful force unleashed when young people resolve to make a change.

If we do not do something to help these creatures, we make a mockery of the whole concept of justice.

We find animals doing things that we, in our arrogance, used to think was just human .

One thing I had learned from watching chimpanzees with their infants is that having a child should be fun.

It was a reward far beyond my greatest hopes.

I’d like to be remembered as someone who really helped people to have a little humility and realize that we are part of the animal kingdom, not separated from it.
