In higher education, the analysis of students’ individual writing assignments after viewing films/documentaries presents an interesting case of using radical ‘messages’ within the aims of environmental education in order to trigger both student’s engagement and critical thinking. The case study “If a Tree Falls and Everybody Hears the Sound” provides an example of how environmental advocacy and the objective of pluralistic education can be combined as mutually supportive means of achieving both democratic learning in which students’ individual opinions are seen as extremely valuable, and simultaneously provide an example of the type of ecopedagogy that supports learning for environmental sustainability. The role of environmental advocacy can be crucially important if the interests of all planetary citizens—and not just one species—are to be taken seriously.
