    • Water, Feedlots, and the Consequences By Corena White
    • Water Crisis
      • 70% of All Water Withdrawals From Lakes, Rivers, and Groundwater Resources Goes Towards Agriculture
      • But More Than Half of the Water Never Makes it To the Crops Because Of Leakage or Evaporation
    • The Role of Climate Change
      • Continued deforestation mainly for the purpose of feedlots and the accumulation of carbon dioxide, methane gas, and nitrous oxide is changing precipitation and temperature patterns
      • Fresh water will be more scarce than ever before if these patterns continue
    • Agricultural Demands
      • Potatoes 500 liters/kg
      • Wheat 900 liters/kg
      • Alfalfa 900 liters/kg
      • Sorghum 1100 liters/kg
      • Corn 1400 liters/kg
      • Rice 1912 liters/kg
      • Soybeans 2000 liters/kg
      • Broiler Chickens 3500 liters/kg
      • Beef 100000 liters/kg
    • Feedlots and Their Damage
      • The damaging product from feedlots is manure
      • U.S. livestock produces 250,000 pounds of excrement per second
      • There are NO sewage systems at feedlots
      • The amount of waste produced annually by livestock which is NOT recycled is 1 billion tons
    • Lagoons, Earthen Pits, and Holding Ponds
      • Lagoons & Earthen Pits hold diluted waste for 6 to 24 months
      • Designed to allow the waste to partially decompose by anaerobic bacteria before field application for “fertilizer”
      • Holding Ponds are used for short-term storage and little decomposing occurs and it is also used for the purpose of “fertilization”
    •  
    • The Pitfalls of the Pits
      • The bottoms of these Pits, Lagoons, and Ponds are not sealed effectively and often these basins are only 30 feet away from ground water
      • Ironically, animal manure “seals” the bottom of the basins and besides the manure only heavy-textured, clayey soils line the bottom
    • When the Pits Runneth Over
      • On June 21, 1995, 25 million gallons of hog urine & feces spilled into New River in North Carolina, when a lagoon holding 8 acres of hog excrement burst
      • 10-14 million fish were killed as a result
      • Some alive fish had open sores, fisherman and vacationers developed body sores, acute memory loss, strange bouts of temper and seizures
    • Legislation?
      • The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)
      • Enacted by Congress in 1980 created a tax on the chemical and petroleum industries and provided broad Federal authority to respond directly to releases or threatened releases of hazardous substances that may endanger public health or the environment
    • Legislation?
      • The Superfund Amendments and Reauthorization Act (SARA) amended CERCLA in 1986; stressed the importance of permanent remedies and innovative treatment technologies in cleaning up hazardous waste sites
    •  
    • Meat-Packing Plants
      • Toll on the Cattle
      • Dangers
      • Undocumented Workers
    • Agricultural Improvements
      • Can Iran Help?
      • Surge Flow Irrigation
      • Low-Energy Precision Application (LEPA)
      • The Drip or Microirrigation
    • Other Suggestions
      • Implement Laws to Halt Deforestation For Cattle Production i.e. feedlots
      • Stop subsidizing water for all meats
      • Mandatory sewage systems
      • Stop the usage of all chemicals on all feedlots then,
      • Find a demand for manure, perhaps the buyers of beef like McDonalds, Wal-Mart, etc., can sell the manure for people’s compost, or use the methane for alternative energies
      • Make Feedlot Waste Laws and Enforce Them
      • Become a Vegetarian or a Vegan
