Down the River Forever

Have you, like me, always wondered how it was possible that half of Iowa's topsoil has ended up down the river?  How we lose 3, 4 or 5 tons a year?
According to a recent article in Mother Jones that you can read at http://www.motherjones.com/tom-philpott/2014/02/iowas-vaunted-farms-are-losing-topsoil-alarming-rate topsoil erosion has increased sixteen times.
The new  culprit is climate change. But some of the old culprits are still with us and at work. I drove by field the other day and snow on the west side of it was black with dirt that had been blown there since the snow melted in the field.
The Mother Jones article describes a brand new and more vigorous sort of erosion in the wake of the drought of 2012 and wettest spring on record that followed in 2013. Making sustainable farming more important than ever.

Something so glaring we shouldn't need a critical eye to see!
