“Most of what has lived on Earth has left behind no record at all.”

“When you grow up in middle America you are inculcated from the earliest age with the belief - no, the understanding - that America is the richest and most powerful nation on earth because God likes us best. It has the most perfect form of government, the most exciting sporting events, the tastiest food and amplest portions, the largest cars, the cheapest gasoline, the most abundant natural resources, the most productive farms, the most devastating nuclear arsenal and the friendliest, most decent and most patriotic folks on Earth. Countries just don't come any better. So why anyone would want to live anywhere else is practically incomprehensible. In a foreigner it is puzzling; in a native it is seditious. I used to feel this way myself.”

“[Australia] is the home of the largest living thing on earth, the Great Barrier Reef, and of the largest monolith, Ayers Rock (or Uluru to use its now-official, more respectful Aboriginal name). It has more things that will kill you than anywhere else. Of the world's ten most poisonous snakes, all are Australian. Five of its creatures - the funnel web spider, box jellyfish, blue-ringed octopus, paralysis tick, and stonefish - are the most lethal of their type in the world. This is a country where even the fluffiest of caterpillars can lay you out with a toxic nip, where seashells will not just sting you but actually sometimes go for you. ... If you are not stung or pronged to death in some unexpected manner, you may be fatally chomped by sharks or crocodiles, or carried helplessly out to sea by irresistible currents, or left to stagger to an unhappy death in the baking outback. It's a tough place.”

“Curiously, among the few survivors from this culinary onslaught is one that is most difficult to understand: the fish knife. Though it remains the standard instrument for dealing with fish of all kinds, no one has ever identified a single advantage conferred by its odd scalloped shape or worked out the original thinking behind it. There isn't a single kind of fish that it cuts better or bones more delicately than a conventional knife does.”

“...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 extrememly salient point: we have been chosen, by fate or Providence or whatever you wish to call it. As far as we can tell, we are the best there is. We may be all there is. It's an unnerving thought that we may be the living universe's supreme achievement and its worst nightmare simultaneously.”

“On a cooler sun on a primordial earth: "I later learned that biologists, when they are feeling jocose, refer to this as the 'Chinese Resaturant Problem'--because we has a dim sun.”

“At the foot of the mountain, the park ended and suddenly all was squalor again. I was once more struck by this strange compartmentalization that goes on in America -- a belief that no commercial activities must be allowed inside the park, but permitting unrestrained development outside, even though the landscape there may be just as outstanding. America has never quite grasped that you can live in a place without making it ugly, that beauty doesn't have to be confined behind fences, as if a national park were a sort of zoo for nature.”
