The current model of meat production and consumption is a Socially Acute Question with environmental implications and developing people’s environmental awareness is necessary for adopting more environmentally friendly eating habits. This work studies the possible effects of a Cartography of Controversy device on the environmental awareness of preservice preschool teachers. Their answers to an open-ended question about their meat consumption were analysed before and after the activity. The results show not significant changes in their willingness to reduce their meat consumption after the activity and health or animal welfare seem to be more relevant reasons for them than the environmental ones. Limitations of this study are discussed in this work.
