Soil - the basis of all land based life
Q. What's wrong with the soil?
A. Half of Iowa's original topsoil has been lost or moved by erosion caused by agriculture. And we've lost half of our black organic matter (carbon) to oxidation from crop production. We can't keep on with this deficit spending of the ecological capital that the prairies bequeathed us, as Wes Jackson has phrased it.
