Chapter 12 Environmental Notes
Questions and answers
Core Case Study: Growing Power-An Urban Food Oasis - correct answer-Food desert
-Urban area where people have little or no easy access to nutritious food
Growing Power, Inc. in Milwaukee, WI
-Uses solar power
-Produces 150 varieties of vegetables
-Runs education program
Whats is food security and Why is it difficult to Attain - correct answer-Many people in
less-developed countries have health problems from not getting enough food, while many
people in more-developed countries suffer health problems from eating too much
-The greatest obstacles to providing enough food for everyone are poverty, war, bad
weather, climate change, and the harmful environmental effects of industrialized food
production
Poverty is the root cause of Food insecurity - correct answer-*Food security*
-All or most people in a country have daily access to enough nutritious food to lead active
and healthy lives
*Food insecurity*
-Chronic hunger and poor nutrition
-Causes:
--Political upheaval, war, corruption, and bad weather
Many people suffer from chronic Hunger and malnutrition - correct answer-*Macronutrients*
-Carbohydrates
-Proteins
-Fats
*Micronutrients*
-Vitamins
-Minerals
*Chronic undernutrition*
-Not enough food to meet basic energy needs
Chronic malnutrition
-Not enough protein or other key nutrients
*Famine*
-Severe shortage of food
-Result in mass starvation, many deaths, economic chaos, and social disruption
Many people do not get enough vitamins and minerals/Many People have health problems
from eating too much - correct answer-Most often vitamin and mineral deficiencies in people
in less-developed countries (quality of the food they are eating is not very nutritious)
Iron
, -Anemia
Iodine
-Essential for thyroid function
*Overnutrition*
-Excess body fat from too many calories and not enough exercise
*Similar health problems to those who are underfed*
-Lower life expectancy
-Greater susceptibility to disease and illness
-Lower productivity and life quality
How is food produced/Food production has increased dramatically - correct answer-We have
used high-input industrialized agriculture and lower-input traditional agriculture to greatly
increase food supplies
Three systems produce most of our food
-Croplands - 77% on 11% world's land area
-Rangelands, pastures, and feedlots - 16% on 29% of world's land area
-Aquaculture - 7%
Three main grain crops - wheat, rice, corn, soy (supply most of the food on earth)
Irrigation - supply of water to crops
Industrialized Crop Production relies on High input Monocultures - correct
answer-*Industrialized agriculture*
-Heavy equipment
-Large amounts of financial capital, fossil fuels, water, commercial fertilizers, and pesticides
-Single crop (only one crop in one area- biodiversity) (monoculture)
*Goal is to steadily increase crop yield*
-Plantation agriculture - cash crops
(Primarily in less-developed countries)
-Increased use of greenhouses to raise crops
Traditional Agriculture often relies on low input polycultures - correct answer-*Traditional
subsistence agriculture*
-Human labor and draft animals for family food
Traditional intensive agriculture
-Higher yields through use of manure and water
*Polyculture*
-Crop diversity
-Benefits over monoculture
*Slash-and-burn agriculture*
-Subsistence agriculture in tropical forests
-Clear and burn a small plot
-Grow many crops that mature at different times
-Reduced soil erosion
-Less need for fertilizer and water
