It is a characteristic of our times that we must keep ourselves informed about relationships among science, technology, and society. I encourage you to provide the class with information about technology-related issues of importance to you so we can discuss them within the context of the course materials. I hope you will watch for media reports on issues that might be of interest to the class. We can talk about a wide range of topics regarding the sociology of technology and risk communication.
I provide a sampler of three technologies of importance to Iowans: large-scale hog confinement operations, food irradiation, and genetically modified foods. Let's not limit our discussions to just these technologies, but let's begin with them. Most likely, some members of the class will be very knowledgeable about one or more of these technologies. Perhaps they will allow us to "pick their brains" about them in our class discussions.
Large-Scale Hog Confinement Operations:
The building of large-scale hog confinement operations in Iowa occurs in response to needed economies of scale to successfully compete in an industry that is experiencing rapid vertical integration and increases in the size of production units. Concerns arise, however, about potential negative effects on human health, reduced quality of life in rural areas, decreased land values, and short- and long-term environmental damage to water and air quality. These concerns have motivated public resistance to the operations as well as calls for additional technologies to reduce undesirable odors and other environmental problems.
Food Irradiation:
Food irradiation--the exposure of food to high energy gamma rays for the purpose of post-harvest insect control, extension of shelf-life, and the killing of harmful bacteria in meats and seafood--has been the focus of heated debate for over twenty years! This controversial technology holds the promise of safer foods that remain fresh longer, but raises health and environmental concerns.
Genetically Modified Foods:
Genetically modified foods are created by transferring genetic material from one organism to another. Proponents say they will reduce dependence upon pesticides, improve the environment, and reduce world hunger. Opponents raise concerns about safety, environmental degradation, and furthering of income inequalities.
