Fast Facts

  • Global demand for livestock products are expected to double over the next 2 decades.
  • If all grain currently fed to livestock in US were consumed directly by ppl, it would feed 800 million.
  • Fossil-Fuel Waste: requires more than 8 times as much fossil-fuel energy than plant production while providing only 1.4 times as much nutrition.
  • Water Waste: uses 87% of fresh water consumption in US. 100,000 L. water/Kg. animal protein vs. 900 L. water/Kg. wheat.
  • More than 50% US grain and 40% of world grain fed to livestock
  • Soil Erosion: feed-grown lands: soil loss avg. 13 tons per hectare per year vs. pasture lands: soil loss avg. 6 tons per hectare per year.
  • 1Kg. meat req. 6Kg. plant protein
  • Energy Waste: Animal protein produced in US req. 28 Kcals for every Kcal of protein produced for human consumption
  • Plenty of Protein: 7 million tons of animal protein produced annually in US-enough for every person to have 79 g. daily with the addition of 34 g. of available plant protein=109 grams protein. RDA=56g of protein.
  • Excrement Waste: 130 times more than human population. Emits hydrogen sulfide, ammonia, methane, and nitrous oxide that contribute to global warming.
  • Water Pollution: Chesapeake Bay: The Chesapeake Bay water shed extends 64,000 square miles and includes the vast dairy farms of Pennsylvania. All the fecal contaminated water run-off enters the watershed and, thus the bay, accounting for a high percentage of the nitrogen and phosphate pollutants there; which has led to eutrophication.
