Summary: The unsustainability of modern agriculture is in part of a measure of its inability to tolerate diversity. Both genetic and ecological uniformity the sameness of fields sown horizon to horizon without interruption, demand costly and often futile reliance on chemicals to protect crops from pests or diseases that are rapidly spreading the evolving. The drive to leave no hectare unplowed worsens soil erosion, pushing tractors onto highly erodible hillside and removing windbreaks, hedgerows and other remnant habitats.
