Polyface Farm in the U

question 60

Essay

Polyface Farm in the U.S. state of Virginia raises beef, chickens and pigs. A particular practice on Polyface Farm is to bring chickens into a pasture after the cows have eaten the grass. The chickens eat the insect grubs that are found in the cow manure. While the chickens fatten up on the insect grubs, they also produce waste, which in turn fertilizes the grass the cows will later eat. Explain this process in terms of sustainable agriculture and the basic principles of sustainability.
