Document Summary
How to increase food supply, increase land area, increase land intensity. Solution = scientific agriculture intensify production on existing land. Application of scientific agriculture (cereal production) increase intensity through plant manipulation. Select for desirable traits especially yield increase yield. Reduce growing time more efficient use of machinery, of food allows for two harvests. Consequences increase food output increased pressure on land extracting more nutrients from the soil. Fertilizer requirements, pesticides and herbicides, irrigation, machinery increased specialization wheat) from suppliers. Monocultural farms/regions specialized, grow only 1 crop (ex. Reduced seed diversity b/c of genetic engineering buy seeds suppliers, don"t save from previous years farmers tied to. Increased susceptibility to disease/pests susceptible pests crop specific; increase. Expansion of agric-business animals/plants both food supply = increase pests farms larger, more into debt complex. The goal reduced time to slaughter animal killed younger; increase food supply increase body weight quickly increase to allow reduced time to slaughter increase output milk, eggs, etc.
