Chapter 19: Genetic Engineering and Biotechnology
The Controversy over Herbicide Resistance through Genetic Engineering
In the Point/Counterpoint in Chapter 18, two scientists, Charles Arntzen and Margaret Mellon, debate the benefits and perils of genetically engineered plants. In the text, I asked you to summarize their views and consider which view most closely relates to your view on the subject.
Furthering the Exploration:
To help you evaluate the Web sites and clarify your own opinion, write down your answers to the following questions. Taking an active part in this exercise will help you prepare for discussions in and out of your class. - What new facts, ideas, and viewpoints, if any, did these web sites provide for you? How did they further your understanding of this issue? Be specific.
- Did your examination and analysis of the material affect your support of one of the two viewpoints presented in the text? If so, explain how and why.
- After reading the material, can you think of an alternative position other than those taken by the authors? Explain it.
- Do you think that the information provided by all organizations and individuals at the web sites you visited was reliable and unbiased? How much of the information was scientific? How much was viewpoint based on ethics?
- Reread one essay from a group in favor of the use of genetically engineered plants and one group opposed to this practice. Underline key words or phrases used to stir the emotions of the reader. What other techniques are used to increase the emotional appeal of each viewpoint?
- Based on your reading, make a comprehensive list of the pros and cons of the use of genetically engineered, herbicide-resistant crop plants. Which side of the issue is most compelling to you? Why?
