“... it occurred to me that never again would he be seven years, one month and six days old, so we had better catch these moments while we can.”

“If your pillow is six years old (apparently average age for a pillow) it has been estimated that one tenth of its weight will be made up of sloughed skin, living mites, dead mites and mite dung.”

“To tell you the truth, I'm amazed we've come this far," he said, and I agreed. We had hiked 500 miles, a million and a quarter steps, since setting off from Amicalola. We had grounds to be proud. We were real hikers now. We had shit in the woods and slept with bears. We had become, we would forever be, mountain men.”

“A third...candidate for Shakespearean authorship was Christopher Marlowe. He was the right age (just two months older than Shakespeare), had the requisite talent, and would certainly have had ample leisure after 1593, assuming he wasn't too dead to work.”

“I mention all this to make the point that if you were designing an organism to look after life in our lonely cosmos, to monitor where it is going and keep a record of where it has been, you wouldn't choose human beings for the job.But here's an extremely salient point: we have been chosen, by fate or Providence or whatever you wish to call it. It's an unnerving thought that we may be living the universe's supreme achievement and its worst nightmare simultaneously.Because we are so remarkably careless about looking after things, both when alive and when not, we have no idea-- really none at all-- about how many things have died off permanently, or may soon, or may never, and what role we have played in any part of the process. In 1979, in the book The Sinking Ark, the author Norman Myers suggested that human activities were causing about two extinctions a week on the planet. By the early 1990s he had raised the figure to about some six hundred per week. (That's extinctions of all types-- plants, insects, and so on as well as animals.) Others have put the figure ever higher-- to well over a thousand a week. A United Nations report of 1995, on the other hand, put the total number of known extinctions in the last four hundred years at slightly under 500 for animals and slightly over 650 for plants-- while allowing that this was "almost certainly an underestimate," particularly with regard to tropical species. A few interpreters think most extinction figures are grossly inflated.The fact is, we don't know. Don't have any idea. We don't know when we started doing many of the things we've done. We don't know what we are doing right now or how our present actions will affect the future. What we do know is that there is only one planet to do it on, and only one species of being capable of making a considered difference. Edward O. Wilson expressed it with unimprovable brevity in The Diversity of Life: "One planet, one experiment."If this book has a lesson, it is that we are awfully lucky to be here-- and by "we" i mean every living thing. To attain any kind of life in this universe of ours appears to be quite an achievement. As humans we are doubly lucky, of course: We enjoy not only the privilege of existence but also the singular ability to appreciate it and even, in a multitude of ways, to make it better. It is a talent we have only barely begun to grasp.We have arrived at this position of eminence in a stunningly short time. Behaviorally modern human beings-- that is, people who can speak and make art and organize complex activities-- have existed for only about 0.0001 percent of Earth's history. But surviving for even that little while has required a nearly endless string of good fortune.We really are at the beginning of it all. The trick, of course, is to make sure we never find the end. And that, almost certainly, will require a good deal more than lucky breaks.”

“In the morning a new man was behind the front desk. "And how did you enjoy your stay, Sir?" he asked smoothly."It was singularly execrable," I replied."Oh, excellent," he purred, taking my card"In fact, I would go so far as to say that the principal value of a stay in this establishment is that it is bound to make all subsequent service-related experiences seem, in comparison, refreshing."He made a deeply appreciative expression as if to say, "Praise indeed," and presnted my bill for signature. "Well, we hope you'll come again.""I would sooner have bowel surgery in the woods with a a stick."His expression wavered, then held there for a long moment. "Excellent," he said again, but without a great show of conviction.”

“For the moment we might very well can them DUNNOS (for Dark Unknown Nonreflective Nondetectable Objects Somewhere).”
