“Here we are, the most clever species ever to have lived. So how is it we can destroy the only planet we have?”

I think the best evenings are when we have messages, things that make us think, but we can also laugh and enjoy each other’s company.

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.

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.

This nation is like a spring freshet; it overruns its banks and destroys all who are in its path.

We shall reach our goal, when we have the power to laugh as we destroy, as we smash, whatever was sacred to us as tradition, as education, and as human affection.

Where others have hearts, he carries a tumor of rotten principles.

Some people are so much afraid of being deceived, that they never venture to trust; like misers, their avarice destroys their gain.

As soon as the fear approaches near, attack and destroy it.

Beneficence is always free, it cannot be extorted by force.

If at first you don’t succeed, destroy all evidence that you tried.

There will be those who seek to destroy you and everything you stand for. No matter what, keep building.
