Industrial scale biomass farming is destroying the eroding the soil. The grassland in the Midwest prairie had uninterrupted millennia to grow and create the soil that grows so much corn and soy today. Iowa has lost 10 inches of topsoil in the last 100 years due to soil erosion caused by industrial farming. Good luck powering your iPad off the corn grown in Iowa when the 8 inches left is gone in the next hundred years and the place literally turns to dust.
