Why More People Means More Wealth (with Marian Tupy and Gale Pooley)

Generations of people have been taught that population growth makes resources scarcer. In 2021, for example, one widely publicized report argued, “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?

Today’s guests, Marian Tupy and Gale Pooley, authors of the new book Superabundance: The Story of Population Growth, Innovation, and Human Flourishing on an Infinitely Bountiful Planet analyzed the prices of hundreds of commodities, goods, and services spanning two centuries, and found that resources became more abundant as the population grew. The two sit down with Trevor to answer questions like; how can we innovate enough to cover the resources needed for 8 billion people? How sustainable is our current mode of sustained innovation? And how is the total sum of atoms different than the sum total of knowledge?
