Growth: From Microorganisms to Megacities

by Vaclav Smil

A systematic investigation of growth in nature and society, from tiny organisms to the trajectories of empires and civilizations.

Growth has been both an unspoken and an explicit aim of our individual and collective striving. It governs the lives of microorganisms and galaxies; it shapes the capabilities of our extraordinarily large brains and the fortunes of our economies. Growth is manifested in annual increments of continental crust, a rising gross domestic product, a child's growth chart, the spread of cancerous cells. In this magisterial book, Vaclav Smil offers systematic investigation of growth in nature and society, from tiny organisms to the trajectories of empires and civilizations.

Smil takes readers from bacterial invasions through animal metabolisms to megacities and the global economy. He begins with organisms whose mature sizes range from microscopic to enormous, looking at disease-causing microbes, the cultivation of staple crops, and human growth from infancy to adulthood. He examines the growth of energy conversions and man-made objects that enable economic activities—developments that have been essential to civilization. Finally, he looks at growth in complex systems, beginning with the growth of human populations and proceeding to the growth of cities. He considers the challenges of tracing the growth of empires and civilizations, explaining that we can chart the growth of organisms across individual and evolutionary time, but that the progress of societies and economies, not so linear, encompasses both decline and renewal. The trajectory of modern civilization, driven by competing imperatives of material growth and biospheric limits, Smil tells us, remains uncertain.

About the author

Vaclav Smil is a Czech-Canadian scientist and policy analyst whose work spans energy, environment, food, population, economics, history, and public policy. Educated at Charles University in Prague and later at Pennsylvania State University, where he earned his Ph.D. in geography, Smil emigrated from Czechoslovakia to the United States in 1969 following the Soviet invasion, before beginning his long academic career at the University of Manitoba in 1972. Over the decades he established himself as a leading voice on global energy systems, environmental change, and economic development, with particular attention to China. Smil has consistently argued that transitions to renewable energy will be gradual rather than rapid, emphasizing the persistence of coal, oil, and natural gas and highlighting the difficulties of decarbonizing critical industries such as steel, cement, ammonia, and plastics. He has also been skeptical of indefinite economic growth, suggesting that human consumption could be sustained at much lower levels of material and energy use. Widely admired for his clear, data-driven analyses, Smil counts Bill Gates among his readers, while colleagues have praised his rigor and independence. Known for his reclusiveness and preference for letting his books speak for him, he has nonetheless lectured extensively worldwide and consulted for major institutions. A Fellow of the Royal Society of Canada and a member of the Order of Canada, Smil remains a highly influential public intellectual.
