The city council of Berkeley, California, has expanded its boycott of oil companies that do business in Burma to include those companies doing business in Nigeria. Included in the boycott are Arco, Chevron, Mobil, Shell, Texaco, and Unocal. Exxon has also long been boycotted due to its slow response to the Exxon Valdez oil spill. City Council member Polly Armstrong commented on the subsequent difficulty in finding gasoline for city vehicles: "In the end, we're going to have to look for mineral rights under the city of Berkeley."
