The usual way of growing cotton is highly petrochemical-intensive, requiring 110 pounds of nitrogen fertilizer per acre. Some of the fertilizer is broken down by soil bacteria into nitrate, a toxic and highly soluble chemical that can leach into groundwater or get washed into lakes, creating oxygenless dead zones.
Patents are like fertilizer. Applied wisely and sparingly, they can increase growth. But if you apply too many chemicals, or make patents too strong, then you can leach the land, making growth more difficult.
Many African smallholder farmers did not share in the 'green revolution' productivity gains driven by modern seeds and techniques, irrigation, and greater fertilizer use in Asia and Latin America in the 1960s.
My mother's first career was physical therapy, her second was writer, and her third career was president of an organic fertilizer company. And she's driven a tank.
People are going to buy cheap fertilizer so they can grow enough crops to feed themselves, which will be increasingly difficult with climate change.
