Section 9.4: Food and Hunger Reading Guidelines
1. Compare a green revolution “high responder crop” to “low responder” crop?
High responder meaning they yield more than other varieties if given optimum levels of fertilizers, water and protection from pests and diseases. Under sub-optimum conditions, high responders may not produce as well as traditional varieties. Poor farmers who cannot afford the expensive seed, fertilizer and water required to become a part of this movement usually are left out of farming altogether.

2. What are proponents of the GMO crop stating?



Proponents predict dramatic benefits from genetic engineering. GMO’s have higher yields and create crops to resist drought, diseases or frost. All of these could be important for reducing hunger in developing countries. Plants that produce their own pesticides might reduce the need for toxic chemicals while engineering for improved protein or vitamin content that could make our food more nutritious.

3. These items are being produced under the GMO concept. Explain how each of these are engineered differently?




Items genetically modified

Examples

Why modified

Crops/Plants


Bananas and potatoes

To contain oral vaccines that can be grown where refrigeration and sterile needles are unavailable.

Plants


To produce industrial oils and plastics.


Animals


Grow faster, gain weight on less food and produce pharmaceuticals such as insulin in their milk. Future – create animals with human cell-recognitions factors that could serve as organ donors.

4. Throughout the 9.4 review and record the consequences of GMO’s:



  • GMO’s could escape and become pests (superweeds)

  • Could interbreed with wild relatives (DNA could persist for many generations)

  • Create superweeds or reduce native biodiversity

  • Could accelerate pesticide resistance in insects or leave toxic residues in soil or on our food

  • Toxic genes or allergies could be transferred

  • Technology available to richest countries or wealthiest corporations

  • Monarch butterflies and beetles die when they eat the BT pollinated crops

  • Creation of “Frankenfoods”?

5. Throughout 9.4 review and record the advantages of GMOs



  • Improve crop yields

  • Create Drought resistant, frost or disease-free plants

  • Tolerant of soggy or salty soil, nutrient low soils allowing degraded farmland to become productive.

  • Reduce hunger in developing nations.

  • Plants produced with pesticides to prevent spraying of toxic chemicals around crops.

  • Can tolerate high doses of herbicide

6. Copy and label Figure 9.19 below:



7. Do you believe that GMO’s should be labeled? Why or why not?



8. Which regulatory agencies are “overseeing” GMOs?

  • The USDA’s Animal and Plant Health Inspection Service (APHIS) regulates the field testing of genetically engineered plants and certain microorganisms.

  • The Department of Health and Human Service’s Food and Drug Administration (FDA) governs the safety and labeling of drugs and the nation’s food and feed supply, excluding meat and poultry.

  • The Environmental Protection Agency (EPA) ensures the safety and safe use of pesticidal and herbicidal substances in the environment and for certain industrial uses of microbes in the environment.

The Department of Health and Human Service’s National Institutes of Health oversees guidelines for the laboratory use of genetically engineered organisms. They are generally voluntary, but are mandatory for any research conducted under federal grants. These are widely followed by academic and industrial scientists around the world.
