Module 33: Sustainable food production

Mod 33: Sustainable agriculture (fishing too)

• Desertification (see above)
  
• intercropping vs. monocropping, see "the three sisters"
  
• Contour cropping: saves space, reduces runoff, preserves top soil (e.g. our garden, most of Asia)
  
• No-till ag: same idea, retains organic material in topsoil, reduces erosion by wind and water
• IPM: integrated pest management (see Lalamilo Farmers)
  
• Organic agriculture (also mentioned in Portlandia and Colin the Chicken)More than just N-P-K, also micronutrients, slower release time, low salinity
  
• CAFO: concentrated animal feed operation (e.g. chickens, pigs, cattle)Usually inorganic feed (purines), hormones and other drugs
  
• Methyl xanthines: caffeine, theobromine, theophyllineevolved plant poisons for insects:
  

• Xanthine: group name
• Caffeine: energy drinks, coffee, soft drinks (to offset drowsiness from insulin spike)
• Theobromine: chocolate
• Theophylline: tea (also a bronchodilator-helps breathing)

• nicotine: tobacco
• caffeine: coffee, tea
• cocaine: coca plants
