Corn Symposium Corn Symposium Presentation Transcript

  • Maiz criollo
  • Domestication of Corn
  • Corn Plant
  • Corn Seed Types
    • Open Pollinated
    • Hybrid
    • Genetically Modified
  • Traits Corn is Engineered For
    • Herbicide Tolerance to Broad Spectrum Glyphosate (Roundup)
    • Insecticidal Properties Conferred by Bt ( Bacillus thuringiensis)
  • A report released by the International Journal of Biological Sciences (Dec. 2009) states that three types of Monsanto corn, cause cancer and organ damage in mammals.
    • The data “clearly underlines adverse impacts on kidneys and liver, to heart, adrenal glands, spleen and haematopoietic system,”
  • Food Sovereignty
    • The right of peoples to healthy and culturally appropriate food produced through ecologically sound and sustainable methods, and their right to define their own food and agriculture systems.
    • The FAO 2004 report acknowledges that GM crops can have reduced yields
    • Genetic modifications address production conditions (insect and weed control), and are not intended to increase the intrinsic yield capacity of the plant.
  • IMF via IndexMundi.com
  • Food Crisis
    • High price of oil
    • Agrofuel boom
    • Increase in grain-fed meat production
    • Weather-related crop failure
    • Market Speculation
    • Holt-Giménez, E. & Patel, R., 2009. Food Rebellions!: Crisis and the hunger for justice, Oakland, Ca: Food First Books.
  • Data source FAO Statistics
  • The USDA breaks Corn Usage into three major categories
    • Animal Feed (45.9%)
    • Food/Seed/Industrial (35.2%)
    • Export (18.9%)
  • Food and Industrial Category
    • Ethanol 24.7%
    • High Fructose Corn Syrup 3.9%
    • Starch 2.1%
    • Sweeteners 1.8%
    • Cereal/Other 1.5%
    • Alcohol 1.0%
    • Seed 0.2%
  • Besides the fact that you only get 1.3 calories of energy per calorie put into ethanol production
    • Researchers at the University of Minnesota,
    • found 5 to 2,138 liters of water used per liter of ethanol
  • This is just water! We're not even talking about:
    • pollution from fertilizer, insecticides, and herbicides;
    • soil erosion;
    • greenhouse-gas emissions from production;
    • competition with food crops.
  • 20 pounds of soil washes away for every gallon of ethanol made
  • In the US 1.5 billion tons topsoil erodes/year
  • No-Till Corn
  • High Fructose Corn Syrup
  • What about Mexico?
    • Studies by the Health Department show that a startling 68 percent of Mexican adults are overweight and 29 percent are obese — just behind the United States, where 74 percent are overweight and 39 percent obese
    • The changing dietary habits have come as Mexico has switched from a largely protectionist to an extremely globalized economy.
    • Since it enacted the North American Free Trade Agreement in 1994, imports of processed food and drinks have soared.
    • The nation now consumes more Coca Cola products per capita than anywhere else in the world: a total of 635 eight-ounce bottles per person each year. The amount represents a threefold increase compared to 1988.
