In Crude World: The Violent Twilight of Oil, New York Times contributing writer Peter Maass explores the underlying forces that make oil a threat to exporting countries and explains alternative strategies for reducing the violence and poverty that our appetite for oil has created overseas. Ed Kashi, author of Curse of the Black Gold, will share his photographic work on the Niger Delta. His work is based on the issues of oil, development, environmental and economic destruction and the pressing issues of sustainability and our unavoidable connection to these dynamics.
