“…environmental damage by livestock may be significantly reduced by lowering excessive consumption of livestock products among wealthy people.” (FAO)
Increased meat consumption has led to feedlot agriculture•Feedlots = huge warehouses deliver energy-rich food to animals living at extremely high popndensities•“Factory farms”•over ½ of the world’s pork and poultry come from feedlots, and much of the beef•CAFO = concentrated animal feeding operation
Concentrated Animal Feeding Operation (CAFO)•“a production process that concentrates large numbers of animals in relatively small and confined places"
CAFOs have benefits and drawbacks•Benefits:•faster & greater production of food•uses less space•Drawbacks:•major sources of water and air pollution•wastes may cause human disease•antibiotics & hormones•ethical?
The Green Revolution involved huge increases in the use of irrigation•Improved technologies:•efficient electric pumps, drip systems•Results:•Dry-season planting (multiple croppings)•Minimize impacts of drought•Cultivation of previously non-arable land
Drip irrigation targets water directly to plants
The Green Revolution: huge increases in the use of fertilizers•Limiting resource = nutrient in shortest supply•synthetic fertilizers can remove these limitations
