Is it true that the world’s rapidly growing population is consuming the planet’s natural resources at an alarming rate that would require two Earths to satisfy the demand for natural resources by 2030? Marian Tupy and Gale Pooley found that resources became more abundant as the population grew. They also found that resource abundance increased faster than the population. On average, every additional human being created more value than he or she consumed. Shermer, Tupy, and Pooley discuss: why we long for the “good ol’ days” • Malthusian trap • Ehrlich’s predictions on overpopulation • the birth dearth • the Simon Abundance Index • compound interest • What does it mean for the economy to grow 2–3% a year? • accumulating wealth • what poorer countries need to do to become richer countries • running out of fossil fuels • Obama’s “you didn’t build that” speech • inflation • electric vehicles • How many people can the Earth sustain? • post-scarcity trekonomics • the future of religion and other social institutions
