What food do we rely on?
• There are 80,000 potentially eatable plants
• We supplied 75 % of our diet from eight
crops
– Top 4 crops: Wheat, Rice, Corn, Potatoes
• Nine staple animals
– Cattle, Pigs, Sheep, Poultry, Goats, Horses,
Mules/Asses, Camels, Buffalo

Where does food come from?
• We supplied our foods from
– Sea
– Estuaries, Continental Shelves, Wetlands, Reefs
– These four ecosystems are 25 times more
productive than the rest of ocean.
– Land
–Available fertile land is 3.7 billion acres,
which can be used easily to produce food.

Apple vs Earth
5
3 of the quarters to represent the oceans
1 of the quarter represents the land
Then slice the quarter in half.
Set aside one half to represent land inhospitable to people
Slice this piece into 4 sections
• 3 sections represent areas too cold, wet, rocky steep or with soil too poor to
produce food, cities, towns, suburbs, highways, shopping centers, schools,
parks, factories, parking lots and other places where people live but do not
grow food.
• Carefully peel the remaining slice. This represents the soil surface on which
humankind depends. It is less than five feet deep.

Terminology
• Starvation: suffering/death caused by deprivation
of nourishment
• Famine: widespread starvation, result of many
factors such as natural disasters, war, etc.
• Undernutrition: Consumption of too few
calories/protein over an extended period of time
(<2,000)
• Malnutrition: Consumption of too little, or too
many, specific nutrients- more about quality than
the quantity of food

Cost of Hunger
• Nearly 800 million people go hungry each day
• One in 7 Americans rely on food programs
• Seasonal hunger – Occurs at a time before new harvest when old harvest
runs out
– In the US, occurs at the end of the month when food stamps run out
• Annually 10 million children under the age five die as a result of malnutrition
• The cost of prevention= $5-10 per children/year

• Attack root causes
– Poverty
– Environmental degradation
• Promote food security
