A discussion on Darfur

Jeffrey Sachs, director of Columbia University's Earth Institute, is one of the world's foremost economists (not to mention one of the world's sexiest economists!) He is most recently the author of The End of Poverty: Economic Possibilities in Our Times. Here is a frank and thought-provoking discussion on the tragic circumstances in Darfur between Sachs and Jonathan Ledgard, Africa Correspondent of The Economist. Sachs gives an in depth analysis of the environmental changes facing Africa and the political and economic implications of these changes.
