The next generation of social entrepreneurs has arrived.  Echoing Green is a global nonprofit organization that provides seed money and fellowships to people who create some of the most innovative solutions to the world's most pressing problems.  Cheryl Dorsey, president of Echoing Green, joins us to talk about this year's fellows, and she'll tell us why you should NOT start another not-for-profit organization.

And we'll talk with about imagining the future.  Katherine's work has linked emerging trends to responsible opportunities for growth in a number of fields, and she's worked to imagine the future of everything from medicine to motherhood.   Her latest project, on behalf of CEOs for Cities, is called VELOCITY: a creative salon that looks to divine the future of cities.
