This podcast studies the ways in which urbanization and urban planning are directly linked to the environment and "livability." Cities are population magnets, and soon two thirds of the world's population will be urbanized. People often move to cities for economic opportunities, and this requires that the public domain be more than a place of automobile passage, but an interface for commerce and human interaction. Seoul is one of those cities, set apart by its focus on creating a positive public environment.

"e²: the economies of being environmentally conscious" is an ongoing PBS documentary series about solutions to the world's most pervasive environmental challenges. The latest addition to the series - "e² transport" - examines transportation alternatives and urban planning in cities around the world. Check your local PBS listings for television broadcast dates in your area.

The "e²" series and its video podcasts are produced by kontentreal, and distributed within the United States by PBS. More information is available at pbs.org/e2/ and e2-series.com/
