“The nine chapters review the basis of environmental education (EE), its later-day evolution into education for sustainable development (ESD), and sustainability education (SE) – and a range of related concepts that provide opportunities for thinking about the future directions for education. The audiences for this discussion can then be thought of as: the insiders of EE and SE, those already part of the movement and who wish to debate theory; outsiders who are trying to understand the point of EE and SE; and, post-graduate research students wanting to engage with the relevant theory.” (Ian Thomas, Enviromental Education Research, 2017)
