There's a certain cast of person I've met—he tends to be a somewhat overweight grad student or adjunct humanities professor with a stubbly neck—whose lip curls slightly when I tell him about my interest in conservation and wilderness preservation. I give him credit for listening, at least: usually when I grouse to a stranger about land-use policy and diminishing biodiversity or share my frustration with our inadequate conceptions of "nature," a visible frost accrues on their corneas. But after hearing me out for a minute, this sanguine fellow raises a finger to remind me that "pristine" spaces in the world are a cultural fiction, adducing theorists like Baudrillard and scientific studies. He's eager to cite a 2017 piece in The Atlantic which summarizes the findings (published in the journal Science) of an exhaustive, cross-disciplinary inquiry into the natural history of the Amazon rainforest:
For more than a quarter-century, scientists and the general public have updated their view of the Americas before European contact. The plains and the Eastern forests were not a wilderness, but a patchwork of gardens, they’ve found. The continents were not vast uninhabited expanses but a bustling network of towns and cities. Indigenous people, we’ve learned, altered the ecology of the Americas as surely as the European invaders did.
For more than 8,000 years, people lived in the Amazon and farmed it to make it more productive. They favored certain trees over others, effectively creating crops that we now call the cocoa bean and the brazil nut, and they eventually domesticated them. And while many of the communities who managed these plants died in the Amerindian genocide 500 years ago, the effects of their work can still be observed in today’s Amazon rainforest....
[C]ultivation eventually altered entire regions of the Amazon, the study argues. Levis and her colleagues found that some of these species domesticated by indigenous people——including the brazil nut, the rubber tree, the maripa palm, and the cocoa tree——still dominate vast swaths of the forest, especially in the southwest section of the Amazon basin....
Some geographers, anthropologists, and indigenous people have all rejected the idea that the Americas were an untouched wilderness——“the pristine myth,” as they call this tale——since the early 1990s. (Fifteen years ago, it was the topic of 1491, Charles C. Mann’s article in The Atlantic, later a best-selling book.) But this paper further belies that myth in one of the most biodiverse places in the continent, suggesting that humans did not just farm in the Amazon but helped determine some of its major ecological communities.
