Environmental education in television narratives: a Brazilian case study

Abstract

This article discusses recent Brazilian research on the relationship between environmental education and cultural studies. Television narratives about the environment and/or sustainability in our everyday lives are used to pose some initial questions about this relation. First, culture is discussed briefly showing how it potentially relates to teaching and informs our role as environmental educators. We argue that culturalist perspectives on research in environmental education politicise teaching practices, even though they are in a context that strays from prerogatives that envisage a future world marked by sustainable development and a green economy. We investigate the impacts of television narratives and images on our everyday lives wherein we are consistently taught particular written and visual messages about how to plan for our future. Examples are draw from the teaching effects of a Brazilian television programme called Repórter Eco, broadcast on a public television network, including the sustainable management of the baru (a typical tree from the Brazilia Cerrado). We argue the educational aspects of television programmes should receive critique, as the relationships established between people and various media artifacts produce particular meanings and ways of seeing the world. This presents a challenge for teachers as examining these subjective ways carefully requires critical examination, not only in terms of education for sustainability or environmental preservation, but also teaching using media.
