In this episode of Urban Nature, physicist Geoffrey West discusses the universal scaling laws that govern organisms, cities, and economies. Drawing from his book Scale, West explains how cities function as networked systems analogous to living organisms, exhibiting predictable patterns of growth, efficiency, and innovation. The conversation explores the implications of these laws for urbanization, sustainability, and the future of the planet, arguing that cities—rather than humanity alone—are the central drivers of the current “Urbanocene.”
