CHAPTER 10AGRICULTURAL ISSUES

#1) Explain the differences and similarities between the following terms: famine, starvation, malnutrition, undernutrition, and chronic persistent hunger.

•Famine: An increase in the # of deaths in a region due to starvation and related diseases that are caused by food shortages.

#1) Explain the differences and similarities between the following terms: famine, starvation, malnutrition, undernutrition, and chronic persistent hunger.

•Starvation: the most extreme form of hunger in which the body wastes away as tissues are broken down to provide energy and nutrients.

#1) Explain the differences and similarities between the following terms: famine, starvation, malnutrition, undernutrition, and chronic persistent hunger.

•Malnutrition: general term that suggests people’s health is being damaged by a diet that does not meet their needs.

#1) Explain the differences and similarities between the following terms: famine, starvation, malnutrition, undernutrition, and chronic persistent hunger.

•Undernutrition: occurs when a person is not getting enough of some nutrient(s).

#1) Explain the differences and similarities between the following terms: famine, starvation, malnutrition, undernutrition, and chronic persistent hunger.

•Chronic Persistent Hunger: any form of malnutrition for an extended period of time. At times the very old or the very young may die, though immune suppression, of diseases such as measles or dysentery.

#2) Describe with specific examples, how technological breakthroughs increased food production in the years up to 1870.

3000 to 4000 BCE•Scratch plow invented – could be pulled by animals

#2) Describe with specific examples, how technological breakthroughs increased food production in the years up to 1870.

500 – 900 BCE•More robust plow for use in heavy soils of N. Europe•Horse collar•Horseshoe

#2) Describe with specific examples, how technological breakthroughs increased food production in the years up to 1870.

1600 – 1870 BCE•Blade on plow•Movements of crops throughout the world•Farming became specialized reducing the number of subsistence farmers•Steam-powered equipment•Selective breeding•Opening of new land (Interior Plains, Australia)

#4)Make a graph and locate the following types of farming operations using an ‘X’

•See blackboard

• #9) When natural disaster strikes a developing country, developed countries often send food-aid. This food aid, however, can disrupt the local economy. The price of locally grown food drops because free food is available, and farmers lose their income as a result. How should donor countries like Canada deal with such situations?

#13a) How are transgenic crops and animals created?

#13b) Create a summary of the advantages of and concerns about GMO products?Advantages of GMO revolution Concerns about GMO revolution

Can create foods (crops/animals) tailored for specific conditions (drought, saline)

Can create nutrition rich foods to target gaps in diets (vitamin A)

GM foods do not require as many pesticides/fertilizers (round-up ready)Terminator technology prevents escape of GM crops into the environment

Impossible to get enough vit A from golden rice

Superbugs - impossible to kill every pest and the offspring of the survivors develop resistanceTerminator seeds (because they are patented) force yearly purchases of what used to be free seedsGMOs are controlled by private companies and thus are not free to allHas enough research regarding harmful effects been done?

#13c) On balance do you personally feel comfortable about eating GMO products? Do you think you have enough information to make an informed choice? Explain.
