By: Paul Sabin


Dive into the gripping story of two brilliant experts, Paul Ehrlich and Julian Simon, who clashed in a fierce public debate over Earth’s future in the 1970s. In his best-selling book, The Population Bomb, Ehrlich warned that overpopulation would lead to widespread famine and disaster. In contrast, economist Simon argued that market forces and technological innovation would come to the rescue. This summary of The Bet by Paul Sabin provides a captivating overview of how their opposing views have shaped the environmental movement, politics, and public discourse, even until today. Explore the intriguing personal backgrounds of these men and uncover how their heated bet regarding commodity prices became a powerful symbol in the ongoing struggle between environmentalism and free-market thinking.

The Clashing Views on Overpopulation

In the 1960s, Stanford professor Paul Ehrlich’s bestselling book The Population Bomb warned of mass starvation due to overpopulation, inspiring the environmental movement. Economist Julian Simon disagreed, arguing that humans’ ability to innovate and adapt would solve problems posed by population growth. The two experts represented opposing views that defined the 1970s debate on humanity’s future. Their differing perspectives played out in politics and still influence public debate today.

Paul Ehrlich: A Biologist’s Journey

Paul Ehrlich, an American biologist, was influenced by Fairfield Osborn and William Vogt’s books during his college years which sparked his awareness about overpopulation and limited resources. Ehrlich linked his study of other species with humanity’s relationship to the environment. He taught at Stanford University for fifty years and wrote extensively in population biology. Ehrlich believed that the world was overpopulated, and without change, humanity was doomed. His views gained wide exposure and met with agreement, but an alternative “contrarian perspective” also emerged.

The Bet That Changed Perspectives

Julian Simon’s views on population control took a dramatic shift as he delved deeper into the issue. He came to realize that Earth’s resources were not limited, and humanity’s demand for them could be addressed through the market economy. As opposed to Paul Ehrlich and his supporters who feared overpopulation leading to famine, Julian Simon showed that population growth was beneficial for society and the economy. Simon’s journey towards challenging Ehrlich’s beliefs began while he was studying advertising at the University of Illinois-Urbana and continued until his famous bet with Ehrlich. Despite suffering from depression, Simon’s dedication to research and rational argument made him challenge conventional wisdom and seek answers through data analysis. The bet itself was an expression of Simon’s inquisitive nature that stemmed from his childhood experiences with his father’s dogmatism. Simon’s personality had many similarities with Ehrlich; however, his approach to the issue of population growth was more optimistic. Eventually, Ehrlich lost the bet, and Simon’s research gained credibility. Julian Simon’s story shows how one person’s willingness to challenge widely accepted beliefs can change the perspective of society.

Limits to Growth

In 1972, the Club of Rome published The Limits to Growth, a groundbreaking study that used computer modeling to predict a disastrous future due to human population growth and extreme resource consumption. This theory was driven by fear that humanity would “overshoot” its boundaries and was further fueled in 1973 by OPEC’s oil production cut that severely impacted the American economy. Some experts believed that “environmental laws” governed human populations, like other species. The study’s goal was to challenge fears about population growth and address the environmental crisis before it was too late.

Environmentalism in Politics

The book explores the rise of environmentalism in politics in the 1970s, focusing on the response to ecological threats from politicians of both major parties. It examines the skepticism of scientists, including Paul Ehrlich and their concerns about the lack of transparency from governments and businesses, and how Jimmy Carter’s presidential campaign was a catalyst in highlighting population growth and environmental issues. The book also looks at Carter’s policy initiatives to conserve energy and create a comprehensive national energy policy.
