Generations of people have been taught that population growth makes resources scarcer. In 2021, for example, one widely publicized report argued that "The world's rapidly growing population is consuming the planet's natural resources at an alarming rate . . . the world currently needs 1.6 Earths to satisfy the demand for natural resources ... [a figure that] could rise to 2 planets by 2030." But is that true?After analyzing the prices of hundreds of commodities, goods, and services spanning two centuries, Marian Tupy and Gale Pooley found that resources became more abundant as the population grew. That was especially true when they looked at "time prices," which represent the length of time that people must work to buy something.
