Study Notes

Undernutrition: A Worldwide Concern

  • 800 million people (approximately 11% of the global population) are chronically undernourished
  • Undernutrition occurs when long-term energy and nutrient intakes are insufficient to meet an individual's needs
  • Factors contributing to undernutrition include:
    • Poverty
    • Civil unrest
    • Wars
    • Lack of access to nutritious food
    • Unfavorable weather conditions
    • Crop failures
    • Lack of clean cooking and drinking water
  • An estimated 485,000 people die each year from diarrheal diseases due to consuming unclean water

Undernutrition During Periods of Growth

  • Undernutrition during pregnancy, infancy, and childhood can have devastating long-term effects
  • In 2018, an estimated 149 million children under 5 years old were stunted, and 49 million were severely underweight (wasted)
  • Undernutrition contributes to 45% of deaths of children under 5 years old
  • Maternal undernutrition can result in:
    • Difficult labor
    • Excessive bleeding after delivery
    • Premature births

  • Bioengineered crops have beneficial characteristics, such as disease resistance, improved flavor, and enhanced nutrition
  • Bioengineered animals, like AquAdvantage Salmon, can grow faster and more efficiently
  • The National Bioengineered Food Disclosure Law requires a national standard for identifying bioengineered foods

Sustainable Agriculture

  • Sustainable agriculture involves farming methods that meet food demands without depleting natural resources or harming the environment
  • Conventional farming methods contribute to:
    • Water pollution
    • Soil erosion
    • Greenhouse gas emissions
    • Deforestation
  • Solutions include:
    • Improving crop yields on existing farms
