What if you could harness the power of the free market to solve the problems of poverty, hunger, and inequality? Impossible? The Nobel Peace Prize winner Muhammad Yunus is doing exactly that. As founder of Grameen Bank, Yunus has created an innovative banking program that provides poor people--mainly women--with small "microcredit" loans they use launch businesses and lift their families out of poverty. The distinguished journalist, author, and CNN host Fareed Zakaria will joined Dr. Yunus in a probing conversation on Yunus's groundbreaking work in social business--finding new ways to use the creative vibrancy of the marketplace to tackle social problems that range from poverty and pollution to inadequate health care and lack of education. This is the second in the Conservators three-part series on Philanthropy in the 21st Century and is made possible through the generous support of The Bank of New York Mellon.
