The data collected represents the articles and academic readings found in relation to the “pros” and “cons” of GMOs. During the qualitative case study process, the data becomes the evidence (Miller 2003). The data collected comes from search engines, databases and magazines.

These sections include the following: “What is GMO,” “The History of GMOs,” “The Position of GMO Supporters,” “The Position of GMO Opponents,” “Controversy Case Studies,” and “Analysis and Discussion". This allowed the information to be organized and made easily accessible during the writing process. By doing a qualitative study, valuable and useful information was collected that helps to further explain what is happening
