Jack and Jill Moved to Their Dream Home in Rural

Jack and Jill moved to their dream home in Rural County.One month later,Otis decided to develop the back 10 acres of his 200-acre farm (nearly all of which had consisted of corn and soybean fields)into a hog-raising operation.Unfortunately for Jack and Jill,the said back 10 acres adjoined their property.Jack and Jill claimed that the smell of the hog operation was overwhelming and that they could no longer enjoy living in their dream home.They also thought the hog operation has caused their property value to decline substantially.Rural County had no zoning regulations in effect.Under what legal theory,if any,may Jack and Jill seek legal relief? Explain.
