“This will surely be called an important book. Ohlson conveys her information in the lively manner of writers such as Michael Pollan and Rowan Jacobsen, making complicated ideas easily accessible to the reader, so that we see the ground at our feet not as dead dirt but rather as, in her words, a “coral reef” teeming with life, a ‘massive biological machine’ on which the health of our species depends. We’re lucky to have this account.”

–Michael Ruhlman, author of The Soul of a Chef
