“Diversity is a survival factor for the community itself. A community of a hundred million species can survive anything short of total global catastrophe. Within that hundred million will be thousands that could survive a global temperature drop of twenty degrees—which would be a lot more devastating than it sounds. Within that hundred million will be thousands that could survive a global temperature rise of twenty degrees. But a community of a hundred species or a thousand species has almost no survival value at all.”

“Give me a kiss, and to that kiss a score; then to that twenty, add a hundred more; a thousand to that hundred: so kiss on, to make that thousand up a million. treble that million, and when that is done, let's kiss afresh, as when we first begun!”

“Fairy tales represent hundreds of years of stories based on thousands of years of stories told by hundreds, thousands, perhaps even millions of tellers.”

“In this way, Edwin Hubble worked out the distances to nine different galaxies. We now know that our galaxy is only one of some hundred thousand million that can be seen using modern telescopes, each galaxy itself containing some hundred thousand million stars.”

“Last year in the U.S. alone more than nine hundred thousand people were reported missing and not found...That's out of three hundred million, total population. That breaks down to about one person in three hundred and twenty-five vanishing. Every year....Maybe it's a coincidence, but it's almost the same loss ratio experienced by herd animals on the African savannah to large predators.”

“The selective voluntary blindness of human beings allows them to ignore the moral consequences of their choices. It has been one of the species' most valuable traits, in terms of the survival of any particular human community.”
