Jacksonville, Florida -- Situated over 850 square miles in the northeastern corner of Florida, Jacksonville is not only the largest city in the United States, it also happens to be the hometown of our host, Al Letson. In this episode, Al looks in his own back yard and discovers stories of a sprawling city in the throws of remaking itself. We learn how a proposed anti-discrimination law is both bringing the community together and splitting it apart, how growing blueberries has become a new mission for veterans suffering from PTSD, and how a group of people recovering from disabling accidents are using sports to rebuild their lives.

The Future of Cities -- For centuries, cities have been bringing people together. Now, for the first time in history, more than half the world's population lives in cities. What draws people to them? What changes when we live closer together? How can cities offer humanity its best hope for a sustainable future? Several TED speakers investigate the future of our urban zones.
