    AP 11: Food

    Modules:
    31: human nutritional needs
    32: large scale farming
    33: farming alternatives

    31:
    24,000 deaths daily from malnutrition
    2200 Cal daily minimum (1 Cal = 1000 cal or 1 kcal)
    Food security
    Famine: local food insecurity, many deaths
    Anemia: iron deficiency
    Kwashiorkor: protein deficiency
    Overnutrition: High Fructose Corn syrup, Red meat (WHO warning 10.27.15)
    Grain vs meat (meat industry is subsidized to use grain for feed)
    food riots 2008 (Egypt, "Arab Spring")
    Bioethanol: corn lobby (Iowa caucus and primary) diverts food to fuel ("national interest")
    how is this sustainable?

    32:
    Impact of transition from hunter gatherer to concentrated ag (historic vs. modern)
    Energy subsidy: petrochemical fertilizers, insecticides, transport (5:1) calories in vs. calories out
    hunter gatherer: 0.1
    farming: 0.5
    fishing 1.0
    US diet 1950: 5
    US diet 2010: 10
    Beef: 20 (e.g. Parker ranch-fly the cows or the feed)
    Offshore fishing: 20+ (also more sharks)
    Review of units:
    1 Watt = 1 joule/second, 4.18 joules = 1 cal, 1000 cal = 1 kcal = 1 Cal
    See figure 32.1 (surprise fishing)
    green revolution: Norman Borlaug Dwarf wheat
    Do the math
    waterlogging: no air to roots
    salinization: minerals left behind from well water (absorbs minerals along the way-contrast with rainwater)
    organic vs inorganic fertilizers (micronutrients)
    Organic: historical fertilizers: mild, labor intensive, gradual decomposition
    Inorganic: Haber process (Nitrogen), WWII and WWI others (phosphates, from nerve gas research)
    Inorganics lead to salinization faster
    Inorganics are very petroleum intensive
    Nitrate runoff (eutrophication)
    monoculture/monocropping-why? economies of scale
    pesticide, herbicide, insecticide (what defines "pest"?)
    Pesticides from WWI and WWII nerve gas research
    persistent pesticides: DDT (silent spring-Rachel Carson)
    pesticide resistance/treadmill
    GMO
    impacts gut bacteria and immune system?
    impact biodiversity?
    labeling-public right to know
    CAFO concentrated animal feeding operation (e.g. feedlots)
    nitrate runoff (see video next)
    fishery collapse and bycatch
    33:
    desertification
    sustainable agriculture
    intercropping
    crop rotation
    contour plowing
    no-till agriculture
    IPM: Lalamilo agreements
    organic ag
    sustainable fisheries
    aquaculture: Costco Salmon color
