    • Eating Lower on the Food Chain Shhh, girls!! I want to hear about this!
    • Union of Concerned Scientists: List of Top Things You Can Do to Help the Planet
      • #1. Drive less
      • #2. Eat less red meat and dairy products
      • #3. Conserve on heating and cooling costs in the home
    • Cow products are the worst!
      • Nearly 87% of our agricultural land (50% for cows alone!) is engaged in animal production for food
    • U.S. Crop % that goes to feed cows
      • 80 - 90% of our soybeans, oats, wheat and corn
      What! You have a problem with that?
    • Cow efficiency
      • It takes 16 lbs of wheat to make 1 lb of cow
      • 5000 gallons of water per lb of cow
      • (A lb of soybeans only takes about 260 gallons of water)
      • A typical North American Diet requires twice as much water to produce as less meat-intensive diets common in Asia and Europe.
      • Eating lower on food chain : same water could feed double the people
      • Making animal products use ½ the water in US
      • 1 dairy cow drinks about 29 gallons of water a day, and needs 40 additional gallons for sanitation, producing only 8 gallons of milk
      Got Water?
    • Pollution (Deep Doo-Doo!)
      • EPA : agricultural runoff = primary pollution source for 60% of U.S. polluted rivers and streams
      • Animal ag. = 130 times more than human waste and equivalent to 5 tons per person.
      • The manure from a 200-head dairy operation produces as much nitrogen as sewage from a town of 10,000 people!
      • One dairy cow produces 120 lbs of waste a day, 12 times as much as a person
      • This is a total of 22 tons per cow per year .
    • Got Trees?
      • Eating a plant based diet personally saves an acre of trees annually
      • 260 million acres of U.S. forests have been cleared for livestock production.
    • Our foreign suppliers
      • Throughout Central and South America, grazing and feed grain production are the leading economic forces behind rainforest destruction.
      • Every quarter lb hamburger costs Mother Nature 55 square feet of forest land!
      • U.S. is the world’s top beef importer.
      • A fast food restaurant can claim to buy from a U.S. supplier but suppliers are not required to declare the nation
      • of origin of their products.
    • Got Petroleum?
      • Americans consume nearly as much fossil fuels at the supermarket as at the gas pump.
      • The typical American burns about 530 gallons of gas each year driving .
      • Eating a meat based diet gobbles up an additional 400 gallons of oil.
      • One acre of corn requires 140 gallons of oil to produce.
      • Eating corn directly maximizes the energy investment.
      • If the corn goes to livestock, only about a fifth of the protein is returned as food, four-fifths is lost
    • Additional tidbits
      • One quarter of all antibiotics produced are used in the U.S. for food animals
      • Foreign originated veggies may have been sprayed with DDT
      • L.A. water is full of DDT, washed off from foreign fruits and veggies!
      • DDT is stored in fat – linked to breast cancer (90% breast cancer patients have DDT in their systems)
