The American Environment

The Cuyahoga River died for our sins . In 1796 the Cuyahoga, which promised easy transportation into the wilderness of the Ohio country from Lake Erie, prompted the city of Cleveland into existence. Over the next 170 years a primitive frontier town grew into a mighty industrial city, one that stretched for miles along the banks of its seminal river.

By the mid-twentieth century, however, the river no longer served as a major artery of transportation, having been superseded by railroads and highways. Now, instead of carrying the products of civilization into the vast interior, it carried the effluent of a far more technically advanced civilization out into the lake. The once crystalline waters of the river had become turbid and rank with its new cargo of chemicals and sewage. Its once abundant wildlife had long since fled, leaving only a few carps and suckers to eke out a living in the foul sullage on its bottom, testifying thereby to the very tenacity of life itself.

The first settlers saw the wilderness not as beautiful but as barren and threatening.

Finally, late in the morning of June 22,1969, the Cuyahoga could no longer bear the burden humankind had placed upon it. In a sort of fluvial cri de coeur , the river burst into flames.

The fire was no will-o’-the-wisp flickering over a transient oil slick. Rather, it roared five stories into the sky, reduced wooden railroad trestles to ruins, and demonstrated to the people of Cleveland and the nation as no scientific study or news report ever could that the burden being placed on the environment was reaching limits that could be crossed only at the peril of the future.

Less than a year later, on April 22, 1970, Earth Day was held, one of the most remarkable happenings in the history of democracy. Fully 10 percent of the population of the country, twenty million people, demonstrated their support for redeeming the American environment. They attended events in every state and nearly every city and county. American politics and public policy would never be the same again.

Today, nearly a quarter-century after the fire, sunlight once more sparkles off the surface of the Cuyahoga. Boaters cruise its waters for pleasure, and diners eat at riverside restaurants. Mayflies —so characteristic of a Great Lakes spring—once more dance in the air above it in their millions while their larvae provide food for at least twentyseven species of fish that have returned to its waters.

The Cuyahoga is not pristine, and barring an alteration in human priorities and circumstances beyond anything now imagined, it will not become so. But it has changed greatly for the better and continues to improve. It is once more a living river.

The Cuyahoga and its history is a microcosm of the American environment. For the history of that environment is the story of the interaction between a constantly changing, ever-more-powerful technology and an only slowly shifting paradigm of humankind’s proper relationship with the natural world.

“DOMINION … OVER EVERY LIVING THING”

Human beings evolved in the Old World, a fact that more than once would have sudden and drastic consequences for the New.

The beginning of the Upper Paleolithic period was marked by a dramatic technological development as humans acquired tools and weapons that were far more sophisticated than any known before and became the most formidable hunters the world has ever known. In the Old World both our prey and our competitors, evolving alongside, quickly learned to treat the emerging biological superpower with the greatest respect, and most were able to adapt successfully. But the New World lay in innocence while human hunters perfected their newfound skills in the Old.

When the land bridge that was a temporary consequence of the last ice age allowed humans to migrate into it, the results were swift and devastating: much of the North American Pleistocene fauna went extinct. Horses, camels, mastodons, mammoths, true elephants, several species of deer, bison, and antelope, ground sloths, glyptodonts, and giant beavers vanished, as did their associated predators, such as saber-toothed cats, giant lions, and cheetahs.

It cannot be known for sure to what extent the arrival of human hunters affected this great extinction, but there is little doubt that it was an important, perhaps fundamental, factor. But the evolutionary equilibrium that had been shattered by the arrival of the superhunters eventually returned, for the human population of the New World, limited by numerous other factors besides food supply, remained low. And the surviving among the species they had encountered quickly adapted to the new conditions.
