that the eocological effects of increasing salmon aquaculture are highly debated (e.g., Naylor et al., 2001). Further consideration would have to be given to this debate if the decision tool were to also incorporate a weighing of the ecological impacts of food choices.
Another alternative format structure might be a comparison of two meal options, as illustrated in Figures 7-4a and 7-4b for the example of consuming a serving of salmon vs. a serving of chicken. Full development of this comparison approach would require information, such as that shown in Table 5-1, on a full range of seafood and other food products that consumers may substitute for each other.
Decision analyses can be presented in several formats (e.g., Figures 7-3, 7-4a, and 7-4b) or used to lead consumers through a decision pathway, for example, via an interactive Web-based program that graphically provides tailored information. In a Web-based format, the consumer could proceed by answering a set of questions such as those shown in Figure 7-1.
