ESR has a glowing review of 1493 by Charles C. Mann (a book I’ve been meaning to pick up myself), which includes a wonderful bit of debunking:
According to the romantic view of “unspoiled nature”, there is a natural equilibrium state of any given ecology (or the biosphere as a whole) which changes only on timescales of a kiloyear or longer. This pristine state is what the ecology tends to return to after major shocks such as volcanic eruptions. Humans are not part of this pristine state. Fortunately, pre-industrial humans have neither the power nor the desire to greatly alter it, and walk lightly on the land. Nevertheless, human presence degrades the pristine state into something that is inevitably less complex, valuable, and natural.
This romantic view has dominated Western popular culture since the early 1800s and underpins a great deal of the silliness and anti-human hostility evident in the modern environmental movement. It motivates, as one very current example, hostility to “unnatural” GM crops and intensive agriculture in general.
Without ever announcing the intention to do so, Mann takes a poleaxe to the romantic view of “unspoiled nature” and dispatches it without mercy. First, he shows how pervasive ecoforming is as a cultural practice. Then, he shows how ecoforming or its sudden cessation can lead to rapid, profound transformation of ecosystems on a continental scale. Then he proposes a not-too-implausible coupling between large-scale ecoforming by neolithic-level savages and the entire planetary climate!
In reality, there is no almost “pristine” nature anywhere on Earth humans can survive with pre-industrial technology. When we look at almost any “wilderness”, part of what we are seeing is the results of millenia of ecoforming by the humans that came before us. And, while attempts at ecoforming sometimes have destructive consequences (salinized soils in the Middle East; rabbits in Australia), as often or more often they lead to a net increase in ecological complexity and resource richness. Mann is not afraid to show us that the world is a better place because, for example, capsaicin peppers native to the New World are now naturalized all over Eurasia and have become important to dozens of Old World cuisines.
I’ve been accumulating news snippets about the as-yet-to-be-formally-scheduled release of Guild Wars 2 for an email newsletter I send out to my friends and acquaintances in the Guild Wars community.
