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?

Some people say, therefore, that violence and war are inevitable. I say rubbish: Our brains are fully capable of controlling instinctive behavior.

Even chimps understand the concept - if a troop of chimps enters a fruit tree, they will only pick the fruits that are ripe and leave the others growing. That is sustainability.

The hardest part of returning to a truly healthy environment may be changing the current totally unsustainable heavy-meat-eating culture of increasing numbers of people around the world. But we must try. We must make a start, one by one.

A chimp would never plan to pull another's nails out.

It's not that humans and non-humans are identical... but the lack of understanding that led to the slave trade is the same lack of understanding many people have about animals today. When slaves were brought over from Africa, many people believed they were not humans, that they didn't have feelings. Many people believe that primates and other animals don't have feelings, too, but they do.

...it honestly didn't matter how we humans got to be the way we are, whether evolution or special creation was responsible. What mattered and mattered desperately was our future development. Were we going to go on destroying God's creation, fighting each other, hurting the other creatures of the His planet?
