1491_ New Revelations of the Americas Before Columbus - Charles C. Mann [4]
Disputes also arise because the new theories have implications for today’s ecological battles. Much of the environmental movement is animated, consciously or not, by what geographer William Denevan calls “the pristine myth”—the belief that the Americas in 1491 were an almost untouched, even Edenic land, “untrammeled by man,” in the words of the Wilderness Act of 1964, a U.S. law that is one of the founding documents of the global environmental movement. To green activists, as the University of Wisconsin historian William Cronon has written, restoring this long-ago, putatively natural state is a task that society is morally bound to undertake. Yet if the new view is correct and the work of humankind was pervasive, where does that leave efforts to restore nature?
The Beni is a case in point. In addition to building roads, causeways, canals, dikes, reservoirs, mounds, raised agricultural fields, and possibly ball courts, Erickson has argued, the Indians who lived there before Columbus trapped fish in the seasonally flooded grassland. The trapping was not a matter of a few isolated natives with nets, but a society-wide effort in which hundreds or thousands of people fashioned dense, zigzagging networks of earthen fish weirs (fish-corralling fences) among the causeways. Much of the savanna is natural, the result of seasonal flooding. But the Indians maintained and expanded the grasslands by regularly setting huge areas on fire. Over the centuries the burning created an intricate ecosystem of fire-adapted plant species dependent on indigenous pyrophilia. The Beni’s current inhabitants still burn, although now it is mostly to maintain the savanna for cattle. When we flew over the region, the dry season had just begun, but mile-long lines of flame were already on the march. Smoke rose into the sky in great, juddering pillars. In the charred areas behind the fires were the blackened spikes of trees, many of them of species that activists fight to save in other parts of Amazonia.
The future of the Beni is uncertain, especially its most thinly settled region, near the border with Brazil. Some outsiders want to develop the area for ranches, as has been done with many U.S. grasslands. Others want to keep this sparsely populated region as close to wilderness as possible. Local Indian groups regard this latter proposal with suspicion. If the Beni becomes a reserve for the “natural,” they ask, what international organization would let them continue setting the plains afire? Could any outside group endorse large-scale burning in Amazonia? Instead, Indians propose placing control of the land into their hands. Activists, in turn, regard that idea without enthusiasm—some indigenous groups in the U.S. Southwest have promoted the use of their reservations as repositories for nuclear waste. And, of course, there is all that burning.
HOLMBERG’S MISTAKE
“Don’t touch that tree,” Balée said.
I froze. I was climbing a low, crumbly hill and had been about to support myself by grasping a scrawny, almost vine-like tree with splayed leaves. “Triplaris americana,” said Balée, an expert in forest botany. “You have to watch out for it.” In an unusual arrangement, he said, T. americana plays host to colonies of tiny red ants—indeed, it has trouble surviving without them. The ants occupy minute tunnels just beneath the bark. In return for shelter, the ants attack anything that touches the tree—insect, bird, unwary writer. The venom-squirting ferocity of their attack gives rise to T. americana’s local nickname: devil tree.
At the base of the devil tree, exposing its roots, was a deserted animal burrow. Balée scraped out some dirt with a knife, then waved me over, along with Erickson and my son Newell, who were accompanying us. The depression was thick with busted pottery. We could see the rims of plates and what looked like the foot of a teakettle—it was shaped like a human foot, complete with painted toenails. Balée plucked out half a dozen pieces
