Then in October, Indian Summer, the air turned so soft, the sunlight so fragile, and each day's loveliness so poignantly doomed that even self-ignorance and restlessness felt like profound states of being, and he just wandered the empty beaches and misty headlands in a state of serene confusion and awe.

For better or worse, zoos are how most people come to know big or exotic animals. Few will ever see wild penguins sledding downhill to sea on their bellies, giant pandas holding bamboo lollipops in China or tree porcupines in the Canadian Rockies, balled up like giant pine cones.

It was cold and windy, scarcely the day to take a walk on that long beach Everything was withdrawn as far as possible, indrawn: the tide far out, the ocean shrunken, seabirds in ones or twos. The rackety, icy, offshore wind numbed our faces on one side; disrupted the formation of a lone flight of Canada geese; and blew back the low, inaudible rollers in upright, steely mist.

Nature made us individuals, as she did the flowers and the pebbles; but we are afraid to be peculiar, and so our society resembles a bag of marbles, or a string of mold candles. Why should we all dress after the same fashion? The frost never paints my windows twice alike.

The worst thing that will probably happen-in fact is already well underway-is not energy depletion, economic collapse, conventional war, or the expansion of totalitarian governments. As terrible as these catastrophes would be for us, they can be repaired in a few generations. The one process now going on that will take millions of years to correct is loss of genetic and species diversity by the destruction of natural habitats. This is the folly our descendants are least likely to forgive us.
