This chapter has two purposes. First, to offer a vision of environmental humanities as an interdisciplinary endeavour that involves the core disciplines of the humanities, as well as their connections with other disciplines and ways of working within the academy and beyond. Second, to draw some conclusions from that vision for the kinds of issues of politics, dialogue and ethics that arise from the real-world problems on which environmental humanities bear. In other words, the chapter attempts to operationalise some of the key messages that the environmental humanities might have to propose in the real-world situation of today. This is a matter first of characterising that situation. Environmental humanities can help us make sense of the challenges that arise, albeit not in isolation. The point of the exercise is to seek appropriate forms of integration between a realm of humanities or humanistic thinking about environmental challenges with a scientific mode of thinking. Second, the chapter considers how humanities thinking can bear on action issues that arise from the situation as thus characterised. What kind of action? How can it be justified? Through which practical mechanisms can it be pursued?
