Moonbay is a home-building corporation that primarily develops retirement communities. farmtex owns a number of feedlots in sunny valley and is the primary employer in the area. moonbay purchased twenty thousand acres of farmland slightly downhill and downwind from farmtex's lot and began building and selling homes on this acreage. farmtex continued to expand its feedlot business, and eventually only 500 feet separated the two operations. because of the odor and flies, in addition to the runoff of feces and other animal byproducts from farmtex's lot, moonbay found it difficult to sell the homes in its development. moonbay wants to enjoin, or prevent, farmtex from operating its feedlot in the vicinity of the retirement home development. under what common law theory would moonbay file this action?
