Running from Alaska's North Slope to Calgary, Canada, the Alaska Gas Pipeline is expected to provide a steady supply of gas and make the United States more energy independent. What are costs to the environment? Will migratory patterns be altered to the point where species die off? Is the focus on natural gas as a "clean" alternative to oil misguided? This anthology tackles these questions and other relevant concerns in accessible essays. Readers will learn about the science and the politics behind the energy revolution, and efforts to extract minerals from the North Slope.
