Abstract
Genetically modified organisms (GMOs) can be defined as organisms in which the DNA has been altered in a way that does not occur naturally. Such methods are used to create GM plants – which are then used to grow (GM) food crops. GM foods have the potential to solve many of the world’s hunger and malnutrition problems, and to help protect and preserve the environment by increasing yield and reducing reliance upon chemical pesticides and herbicides. Nevertheless, the consumption of GM foods provokes doubts and hesitations among consumers, especially in Italy. This paper has two aims, the first is to investigate genetically modified (GM) foods consumption in Italian high school students through a large sample size survey on 2122 students randomly selected in 39 schools of a metropolitan area (Naples, South-Italy). The second, by examining the behavioural process that drives individual’s perceptions of GM food taking advantage of an empirical choice methodology that corrects for endogeneity in decision making relationships, namely structural equation model (SEM). The results show that a very large percentage of students never or rarely eat GM food and a lot of them do not suggest the consumption of GM food. The proposed SEM is a full formative measurement model and shows that GM foods consumption in Italian students depends on the knowledge of GMO and on the impact of the GMO on the men’s health and on the environment. Therefore, in order to orient population it could be realized a standardized evaluation systems relative to human health and environment consequences produced by GM organisms and GM foods.File | Dimensione | Formato | |
