David and Marcia Pimentel’s, “Land, Energy, and Water: The Constraints Governing Ideal U.S. Population Size,”* is the most important article I have ever read on the question of optimal United Statespopulation size and resource availability. Two years ago the U.S.population passed the 300 million mark and, thanks largely to immigrants and their descendants, is well on our way toward 400 million and more.

Yet, as David and Marcia Pimentel of Cornell University, argue here, the United States only has the resource base to support a population far smaller (at near the standard of living most Americans currently enjoy). Since their article first appeared over sixteen years ago, I have yet to encounter a convincing refutation of their main points. One of the obvious implications is that we should be taking positive steps to shrink U.S.population to a sustainable level, including ending immigration-fueled growth.
