“Each species with which we share the earth is a success story. Each of our cohabitants has evolved an ingenious set of life strategies, and made them work. To live on an earth without fascinating, often beautiful creatures would be to live on a lesser earth. The trick is not to let them slip away, but to understand and help them on their terms.”

“The earth is so beautiful. We are beautiful also. We can allow ourselves to walk mindfully, touching the earth, our wonderful mother, with each step. We don't need to wish our friends, 'Peace be with you.' Peace is already with them. We only need to help them cultivate the habit of touching peace in each moment."-”

“The fact is that no species has ever had such wholesale control over everything on earth, living or dead, as we now have. That lays upon us, whether we like it or not, an awesome responsibility. In our hands now lies not only our own future, but that of all other living creatures with whom we share the earth.”

“Humanity is a biological species, living in a biological environment, because like all species, we are exquisitely adapted in everything: from our behavior, to our genetics, to our physiology, to that particular environment in which we live. The earth is our home. Unless we preserve the rest of life, as a sacred duty, we will be endangering ourselves by destroying the home in which we evolved, and on which we completely depend.”

“Every living creature on the earth is special. You want to be the one that puts an end to one of them?”

“The crew of the space shuttle Challenger honored us by the manner in which they lived their lives. We will never forget them, nor the last time we saw them, this morning, as they prepared for their journey and waved good-bye and 'slipped the surly bonds of earth' to 'touch the face of God. ”
