Liquid manure from intensive pig farming creates environmental conditions that harm aquatic animals and local wildlife through nutrient pollution and oxygen depletion.
Slurry pollution events cause mass fish kills with significant animal welfare consequences. Aquatic animals experience oxygen starvation, a painful and distressing death. Beyond acute events, chronic nutrient enrichment degrades habitat quality for thousands of aquatic species. Waste management reform in intensive livestock is both an environmental and animal welfare imperative.
