Environmental Malthusianism and demography

As anthropogenic climate change threatens human existence on Earth, historians have begun to explore the scientific antecedents of environmental Malthusianism, the idea that human population growth is a major driver of ecosystem degradation and that environmental protection requires a reduction in human numbers. These accounts, however, neglect the antagonistic relationship between environmental Malthusianism and demography, thereby creating an illusion of scientific consensus. This article details the entwined histories of environmental Malthusianism and demography, revealing points of disagreement – initially over methods of analyzing and predicting population growth and later over the role of population growth in ecosystem degradation – and moments of strategic collaboration that benefited both groups of scientists. It contends that the image of scientific consensus in existing histories has lent support to ongoing calls for population control, detracting attention from more proximate causes of environmental devastation, such as polluting modes of production, extractive business practices and government subsidies for fossil fuel development.
