Imagine:
• You often go hungry.
• Your children say they’re hungry but you know there’s not enough food in the house.
• Your children go to bed hungry and dream of food.
• You frequently skip meals because you lack food, money transportation and kitchen appliances.
Hunger Facts:
• 1 in every 5 people worldwide experiences persistent hunger.
• One person dies of starvation every 2 seconds.
• In the U.S.: 36 million people; 1 out of every 5 children, lives in poverty
Food insecurity: The limited or uncertain availability of nutritionally adequate and safe foods
Food poverty: Hunger occurring when there is enough food in an area but cannot be obtained due to a lack of money, deprivation, war or other problems
FON 241 Principles of Human Nutrition; L. Zienkewicz
Hunger HotspotsNote: Areas with stripes of color have multiple causes of hunger.
Worldwide Food Shortages
Famine: Extreme food shortage in an area that causes widespread starvation and death.
Causes- 1. Political reasons 2. Armed conflict (war) 3. Natural Disasters
Global Malnutrition• Approximately 2 billion people
are malnourished
• Mostly lacking in iron, iodine, Vitamin A and protein/ calorie malnutrition

Questions:
Why is it that malnutrition is such a worldwide problem when we have an ample food supply?
What will happen in the future?
The Cycle… The Problem?
• Population growth leads to hunger and poverty.
• Hunger and poverty lead to population growth.
How can we stop this cycle?
Poverty, Overpopulation, and Environmental Degradation

Environmentaldegradation—resources dwindleas the number ofpeople needingfood grows
HungerPoverty
The interactions of poverty, overpopulation, and environmental degradation worsen hunger.
Environmental Limitations
• Soil erosion, compaction and salinization
• Deforestation and desertification due to overgrazing
• Climate changes due to forest destruction
• Water pollution
• Extensive overgrazing
• Overfishing
Solutions?…
1. Increase economic growth: sustainable development
2. Slow population growth: decrease the number of children in families
3. Make changes at home…
Questions to think about:
• What is the earth’s carrying capacity?
• Will the population outgrow the food supply?
