Earth Day brings environmental awareness to the forefront of our attention, reminding us to be conscious of our choices everyday. Do something - get active today. There's plenty of information at www.earthday.net about how one can promote planetary health through consumer and political choices.

One aspect of ecological awareness is education. We choose the books we consume, and with that in mind I'd like to call your attention to American Earth: Environmental Writing Since Thoreau, published today by The Library of America.

Edited by author and green activist, Bill McKibben, American Earth collects essays from classic conservationist voices such as Henry David Thoreau, John Muir, and Aldo Leopold with contemporary authors like David Quammen, Barbara Kingsolver, and Michael Pollan. It's truly a definitive volume born in the historical connection between environmental writing and activism.
