Answer to Question 1
Multinational corporations that hire indigenous people for below-subsistence wages to grow crops to be exported for profit leave little fertile land on which local farmers can grow food. Export-oriented agriculture consumes the labor, land, capital, and technology that are needed to help local families produce their own food. Besides diverting acreage from the traditional staples of the local diet, some multinational corporations also contribute to hunger through their marketing techniques, which lead consumers with limited incomes to associate products such as cola beverages, cigarettes, infant formulas, and snack foods with Western culture and prosperity.
Answer to Question 2
Essentially the differences are in the timing of data collection, the extent and nature of the data collected, and the purpose or use of the data. Nutrition screening is a system that identifies specific individuals for nutrition or public health intervention, often at the community level. Nutrition assessment is the measurement of indicators of dietary status and nutrition-related health status to identify the possible occurrence, nature, and extent of impaired nutritional status (ranging from deficiency to toxicity). Nutrition monitoring is the assessment of dietary or nutritional status at intermittent times with the aim of detecting changes in dietary or nutritional status. Nutrition surveillance is the continuous assessment of nutritional status for the purpose of detecting changes in trends or distributions so that corrective measures can be taken.
