I became intensely aware of the being-ness of trees. The feel of rough sun-warmed bark of an ancient forest giant, or the cool, smooth skin of a young and eager sapling, gave me a strange, intuitive sense of the sap as it was sucked up by unseen roots and drawn up to the very tips of the branches, high overhead.

If everybody on the planet today had the same standard of living as the average European or American, we would need three new planets. But we don't even have one new planet. We have this one, and with the way we're polluting it, the shrinking water resources, the climate change, the experimentation with plants... the outlook is grim.

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 was even accused of teaching the chimps how to fish for termites which I mean that would have been such a brilliant coup.

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?

I never wanted to give up. I thought I might have to. Especially at the beginning when chimpanzees had never seen a white person before.They gave one look at me and ran away! They were scared, but eventually I got their trust.

I urge you to read Eternal Treblinka and think deeply about its important message.
