Shownotes Transcript

It’s easy to take growth for granted, for it to seem expected, inevitable even. Every person starts out as a baby and grows up. Plants grow from seeds into food. The economy grows. That stack of mail on your table grows. But why does anything grow the way that it does? In this hour, we go from the Alaska State Fair, to a kitchen in Brooklyn, to the deep sea, to ancient India, to South Korea, and lots of places in between, to investigate this question, and uncover the many forces that drive growth, sometimes wondrous, sometimes terrifying, and sometimes surprisingly, unnervingly fragile.
