Episode notes

Two thirds of people are going to be living in cities before too long. The urban footprint is such a small, small footprint compared to agricultural land. But because there are so many people moving to cities, they walk more, bike more. There's less sewer line laid per capita. And and there's a lot of hopes planned on reducing greenhouse gas missions as more people move to cities.

The concept of the city is a crucial one for human civilization: people living in proximity, bringing in resources from outside, separated from the labors of subsistence so they can engage in the trade of goods and ideas. But we are still learning how cities grow and adapt to new conditions, as well as how we can best guide them to be livable as well as functional. I talk with urban scientist Catherine Brinkley about the structure of cities, including the fractal nature of their shapes, as well as what we can do to make cities thrive as much as possible.
