"Kentucky is the heart of America's horse industry for breeding, racing, and all things thoroughbred. The economic impact of horse racing in Kentucky makes these equestrian assets as vital as Bourbon to local economy. But the boon of industry comes at a price. Poorly managed horse farms that allow over grazing, large untended manure piles, and soil erosion can cause great harm to local water ways and eco-systems."
