Digest

This podcast explores the "Malthusian Swerve," a recurring pattern where humanity narrowly escapes resource depletion through timely technological advancements. The discussion features an interview with economist Jeff Guo, who provides historical examples like the shift from whale oil to kerosene and the development of synthetic fertilizers after guano depletion. Guo explains how scarcity drives innovation, but this reactive approach often prioritizes short-term gains over long-term sustainability. The podcast examines the current oil crisis and fracking as a recent example of the Malthusian Swerve, questioning whether it's a genuine solution or a temporary reprieve. Ultimately, the discussion emphasizes the need for a more sustainable approach to resource management and economic growth, moving beyond a reliance on last-minute solutions.

Show Notes

Earth can sustain life for another 100 million years, but can we?

In this episode, we partnered with the team at Planet Money to take stock of the essential raw materials that enable us to live as we do here on Earth—everything from sand to copper to oil— and tally up how much we have left. Are we living with reckless abandon? And if so, is there even a way to stop? This week, we bring you a conversation that’s equal parts terrifying and fascinating, featuring bird poop, daredevil drivers, and some staggering back-of-the-envelope math.
