The air we breathe is twenty-one percent oxygen, an amount higher than on any other known world. While we may take our air for granted, Earth was not always an oxygenated planet. How did it become this way? Donald Canfield—one of the world's leading authorities on geochemistry, earth history, and the early oceans—covers this vast history, emphasizing its relationship to the evolution of life and the evolving chemistry of the Earth.

Now students learn to earn. Natural Literacy strives to motivate students and faculty to instead learn to love. What do we truly want to know? Doug Dix proposes that readers discover authentic answers by repairing their motives and returning to their natural roots. His perspective is innovative and certain to be controversial.
