Population, resources, and environment: "beyond the exponentials" revisited

More than half a century ago, Trewartha (1953) argued that population was a pivotal element in geography and that its neglect would affect the future development of the discipline. Subsequently, geographers paid more attention to population than they had previously, perhaps, but still not enough. My purpose is to revisit Zelinsky's article, "Beyond the Exponentials: The Role of Geography in the Great Transition"; to update what has happened since it was published, at least with respect to basic population changes; to raise some questions about neoclassical economics and the growth syndrome; and to encourage geographers, once again, to engage population issues as an integral element of geographic studies, especially those focused on resource use and environmental degradation.
