Factory Farming

Hogs are kept in sheds with grated floors that allow everything to pass down to the pipes that drain to large waste lagoons. All manner of waste collects in these impoundments, from fetuses to fecal matter. Due to the drugs and hormones fed the sows (females), their feces are pink. Once this aggregate is together in a lagoon,the wind will tend to accumulate the floating solids in one place.
