A growing field of research is environmental humanities. This is a result of the increased awareness that mankind’s great challenges can’t be solved solely by science. Climate change, for instance, is not only a question of information or technology. It is dependent of millions of citizens making everyday choices between values that are in conflict with each other, for example to refrain from eating meat even though it is delicious, or for a local politician, to implement tolls to reduce traffic, against the will of motoring voters. Humanities and communication studies have proven fruitful for the understanding of why people choose and react as they do and for understanding the conditions for change. Rhetoric has a rather unemployed potential in this endeavor. This article charts the background and research front of environmental rhetoric and suggest three lines of further studies and an approach to integrate research, teaching and citizenship.
