Food Production- Nutrition and Types of Agriculture
Nutrition and Malnutrition
For good nutrition: large amount of micro and macronutrients
Undernutrition is when there is lack of food and basic needs & Malnutrition is when you consume a diet that lacks all the nutrients you need.
Poverty is the root cause of hunger and malnutrition.
Systems that supply food
Crops are grown without the use of synthetic pesticides or engineered seed varieties.
Synthetic Fertilizers- chemicals that contain nutrients
Synthetic Pesticides- control pests and organisms harmful to plants
Irrigation- water supplition
Negative Aspects: uses heavy equipment that requires a lot of gas, loss of capital, large amounts of fossil fuel and water.
Traditional subsistence: energy of the sun with human labor and draft animals.
Traditional intensive: Higher crop yields by increase human and draft animal inputs.
Rangelands, Pastures & Feedlots
Industrialized meat production comes with health risks. Growth hormones and antibiotics enter the human food chain and there are concerns for antibiotic resistance.
Half of meat production comes from rangelands pastures and feedlots. The other half comes from intensive factory systems.
Fisheries & Aquaculture
Fishery: concentration of a particular aquatic species suitable for commercial harvesting in a given ocean area or inland body of water.
Aquaculture: Practice of raising fish in freshwater lakes/ponds, in rice paddies and in coastal and deeper ocean waters.
