Are Urban Industries Endangering Neighborhoods?

Louisville's Rubbertown neighborhood is home to the largest carbide (a chemical compound) furnace in the world. Several miles east, the Butchertown neighborhood hosts one of the nation's largest urban slaughterhouses. There were accidents at both of these facilities in the same week in late March, and the city is developing a new notification system for residents. Such a system is necessary, city officials say, because these facilities are in urban areas. What dangers do these facilities present to the surrounding neighborhoods, and to the city as a whole? Should the plants be relocated? Can they be relocated? What is the future of urban industry, and what will happen to the workers if the plants move?
