On today’s show, we’ll explore the nature of competitiveness—and how understanding why we compete provides insights into biology, economics and psychology! Then, two-time Booker Prize-winner Peter Carey discusses his new novel Parrot and Olivier in America. Also, journalist Peter Lovenheim realized he didn’t know anyone who lived on his suburban street. He’ll tell us about setting out to change that…by asking to sleep over at neighbors' houses. Plus, we’ll take a look at how cities like New York, Portland, and San Francisco are at the forefront of the urban sustainability movement.
