The American Environment

The early settlers, while they greatly altered the landscape of the Eastern seaboard, clearing whole stretches of the primeval forest and converting the land to fields, pastures, and meadows, did not greatly diminish the biological diversity. They opened up the best land for farming but left untouched the steep or rocky areas as well as, to a great extent, the wetlands and mountains. Indeed in some ways the early settlers increased the diversity by expanding habitat for such grassland species as bluebirds, ground hogs, and meadowlarks. The ecosystem as a whole remained intact.

North America was transformed within a century. There was a vast price to pay.

Only in the South, where plantation agriculture became the rule in areas to which it was suited, did monocultural husbandry greatly diminish the fertility and texture of the soil. Virginia, the largest and, thanks to its tobacco exports, most powerful of the colonies, found its yields declining sharply toward the end of the eighteenth century as the best land was exploited and exhausted. Erosion became an increasing problem. As early as the 178Os Patrick Henry thought that “the greatest patriot is he who fills the most gullies.”

“A THOUSAND YEARS”

Meanwhile, as a new civilization was being built out of the wilderness of North America, new attitudes toward wilderness itself were emerging in Europe. The ancient paradigm that had gripped Western thinking since Genesis was beginning, partially, to shift at last.

In the seventeenth century, wilderness had been universally regarded as at best a waste, if not an evil. In the eighteenth, however, it began to be seen for the first time as a thing of beauty. Mountains came to be viewed as majestic, not just as an impediment to travel or a barrier against invasion.

In Britain the aristocracy began to lay out gardens, such as those by Capability Brown, that were highly stylized versions of nature itself, rather than the direct refutation of it that seventeenth-century gardens, like those at Versailles, had been.

Biology became a systematic science (although the word itself would enter the language only in the early nineteenth century). Linnaeus studied the relationships of plants and animals. Georges Cuvier, William Smith, and others began to examine fossils and to sense, for the first time, a history of the earth that was at variance with the account given in Genesis.

The new attitude toward wilderness soon came to this country and contributed to the growing American sense of uniqueness. James Fenimore Cooper’s novels and Thoreau’s essays displayed a love of wilderness that would have been inconceivable a century earlier.

Of course, in Europe wilderness was largely an abstraction. In America it was just down the road. At the end of the Revolution, it nowhere lay more than a few days on horseback from the Atlantic shore, and Thomas Jefferson, no mean observer, thought it would be “a thousand years” before settlement reached the Pacific.

Jefferson was wrong. He did not realize—no one could have—that a third technological revolution was just getting under way, one that would give humankind the power to transform the world far beyond anything provided by the first two. It had taken millennia to reshape the face of Europe to human ends. North America would be transformed in less than a century. But there would be a vast price to pay for this miracle.

The steam engine and its technological successors allowed energy in almost unlimited quantity to be brought to bear on any task. So forests could be cut, fields cleared, dams built, mines worked with unprecedented speed. As a result, in less than a single human lifetime an area of eastern North America larger than all Europe was deforested. Virtually uninhabited by Europeans as late as 1820, the state of Michigan by 1897 had shipped 160 billion board feet of white pine lumber, leaving less than 6 billion still standing.

 

But the new engines needed fuel. At first waste wood supplied much of it, and later coal and then oil. The by-products of this combustion were dumped into the atmosphere as they had always been, but now their quantity was increasing geometrically. In 1850 Americans were utilizing more than eight million horsepower, animal and mechanical. By 1900 nearly sixtyfour million, almost all mechanical, was being used by what economists call prime movers.

The factory system and mechanization brought many commodities within the financial reach of millions, while new transportation systems created national markets and made economies of scale both possible and necessary. This, in turn, caused the demand for raw materials to soar. The great mineral wealth that was being discovered under the American landscape was exploited with ever-increasing speed. Again the waste products were dumped at the lowest possible cost, which meant, in effect, on the far side of the nearest stone wall.
