Dirt: The Erosion of Civilizations

Written by David Montgomery

Dirt:  The Erosion of Civilizations  is about societal suicide.  Dr. David Montgomery details, in case after case, the collapse of civilizations caused by unintentional agricultural abuse leading to loss of topsoil.  Topsoil takes centuries to accumulate; tons per acre can be lost in decades.  The fertile soil of the American Great Plains is being flushed down the Mississippi.  The world's population is exploding but Earth's arable land is shrinking.  An agricultural revolution--actually, the adoption of known technologies such as organic and no-till farming could prevent our current global society from starving to death.
