Poultry farmers all over the globe are running into serious problems with the waste from chickens, which is real trouble when it gets into the water supply. Years back John Logan, a farmer from Prentiss, Mississippi, noticed the same problem. In an interview with NPR radio he recalled, "I said, 'I got to do something.' I can't be putting this on the ground. Now, I have a river right here. What's to happen when that phosphorus overload washes into the river, which then ends up in the Gulf of Mexico?"
