This study explores how the internet media construct GM foods by comparing popular science, agriculture, and environmental media concerning the sources, scientific evidence, and positions. The results indicate significant differences among the three types of internet media on the position of GM foods. Popular science media tend to neutralize and support GM foods, while agricultural and environmental media are mostly opposed and neutral. Although the media of different attributes have different positions on GM foods, the information sources are mainly from professional elites and government organizations, similar to traditional media. The agricultural and environmental media are more likely to cite non-profit organizations as their sources; however, as a whole, scholars, experts, and governments are the majority. Internet media indeed have diversified positions and opposing discourses on technology and risk hazards, but academic experts and the government mainly dominate these discourses. |
