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.

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

Peace starts within.

Arguably, we are the most intellectual creatures that’s ever walked on planet Earth. So how come, then, that this so intellectual creature is destroying its only home?

Cruelty is a terrible thing. I believe it is the worst human sin.

I love dogs, not chimps. Some chimps are nice, and some are horrid. I don’t actually think of them as animals any more than I think of us as animals, although both of us are.

Someday we shall look back on this dark era of agriculture and shake our heads. How could we have ever believed that it was a good idea to grow our food with poisons?

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.
