From Iraq and Saudi Arabia to Equatorial Guinea and Ecuador, what has been the impact of oil on the countries that produce it? To what extent has petroleum production helped or hurt nations develop not just economically, but also politically and socially? And, how have campaigns like that of Hugo Chávez’s to redistribute oil wealth in Venezuela created new economic and political crises? With a focus on the rebels, royalty, environmentalists, indigenous activists, dictators and CEOs associated with the petroleum industry, Peter Maass examines the world that oil has created. A contributing writer to The New York Times Magazine, Maass has reported from the Balkans, Middle East, Asia, South America and Africa for The New Yorker, The Atlantic Monthly, The Washington Post, and Slate.
