Art and creativity have been central to environmental adult education for a long time. In this presentation, I will begin by laying the foundations of environmental adult education, and then share various types of arts-based initiatives by individual artists as well as community-based practices. I will pursue with a discussion of a very new practice of environmental adult education – The Ecological Museum Hack. The Hack is designed as a means to analyze critically the representations of nature and society in art and cultural institutions that actively shape our ways of seeing so as to exercise power over how we understand ourselves, and our historical and current relationships to the environment.
