To the author, Oxford historian Felipe Fernández-Armesto, a society's relationship to climate, geography, and ecology are paramount in determining its degree of success. "Unlike previous attempts to write the comparative history of civilizations," he writes, "it is arranged environment by environment, rather than period by period or society by society." Thus, for example, tundra civilizations of Ice Age Europe are linked with those of the Inuit of the Pacific Northwest, the Mississippi Mound Builders with the deforesters of eleventh-century Europe. Civilizations brilliantly connects the world of ecologist, geologist, and geographer with the panorama of cultural history.
