“…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 pop n densities “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
