Textbook Question
Chapter 20, Problem 2QC
GM foods are created for a variety of reasons, from resistance to herbicides to the delivery of vaccines and vitamins. Should we permit the development of some GM foods and not others, and if so, which GM foods should we allow? Defend your position.

In October 2002, the government of the African nation of Zambia announced that it was refusing to distribute 15,000 tons of corn donated by the United States, enough corn to feed 2.5 million Zambians for three weeks. The government rejected the corn because it was likely to contain genetically modified kernels. The government made the decision after its scientific advisers concluded that the studies of the health risks posed by GM crops “are inconclusive.” Do you agree with Zambia’s decision to turn away the corn? Why or why not? In your answer, consider that at the time, Zambia was facing food shortages, and 35,000 Zambians were expected to starve to death over the next six months. How do the risks posed by GM crops compare to the risk of starvation?
AquAdvantage salmon is a genetically modified (GM) Atlantic salmon developed by
AquaBounty Technologies. The Food and Drug Administration (FDA) has approved the
company's application to allow the entry of this GM salmon into the United States food supply
late last year. The FDA announced that: "AquAdvantage salmon is as safe to eat as any non-
genetically engineered (GE) Atlantic salmon, and also as nutritious."
However, opponents of genetically modified food are claiming that the AquAdvantage salmons
could pose a serious environmental risk to the marine ecosystem if the engineered fishes escape
from the farms. These transgenic salmons would be a big threat to the wild salmons. Justify this
statement.

- Much of the controversy over genetically engineered foods has centered on whether special labeling should be required on all products made from genetically modified crops. Some people have advocated labeling that identifies the product as having been made from genetically modified plants. Others have argued that food labeling should be required to identify only the ingredients, not the process by which they were produced. Choose a side in this issue and justify your stand.arrow_forwardA. Hank is going to talk about Gene Guns and Agrobacterium which I will discuss in a video lecture next week. B. How long does it take to develop and bring a GMO crop to market? C. What are some of the drawbacks to GE organisms? D.One of the interviewees is a woman in bright pink t-shirt and she is trying to describe drawbacks to GMOs. While not a cogent argument, I think there is an important point that she is trying to make. Do you know what she is trying to say?arrow_forwardGenetically modified organisms (GMOs) are used to create human growth hormone, insulin and clotting factor proteins that are used to treat dwarfism, diabetes and hemophilia respectively. Several crops such as corn and soybean have also been genetically modified in order to facilitate either the management or growth of these crops. Why do you think there is push back or opposition against the use of GM food crops but not in the use of products such as insulin, which is also created using GMOs?arrow_forward
- GMOs can be used to create an increased crop rate at a lower price and therefore can be used to solve the problem of world hunger. Introducing GMOs to third world countries can conserve labor, resources, and land. Nutritional value and vaccines added to the crops can improve life in the countries. These proven benefits outweigh the fact that allergies and effects on wild plants are only potential.

Why might a person choose to use selective breeding over genetic modification? Why might a person choose to create a GMO over a selectively bred organism? Use three to five sentences to formulate your argument.arrow_forward
- On the following pages, you will be asked the same question seven times: "Based on what you now know, do you think we should raise genetically modified (GM) crops?" Each time, you must answer Yes or No to that question, and each time, depending on how you responded, you will be presented with a new counterargument meant to challenge your stance. Thus, this feature presents six arguments for growing GM crops and six against, but whenever you answer yes or no, you will only see one side of the argument -- the one meant to challenge your position. However, before answering the question for the seventh and final time, you will be shown all 12 arguments for and against. At that point, you may choose Yes, No, or Undecided and then see where your vote stands vis-à-vis those of others.
