The term “sustainability” emerged in the early 1970s to emphasize the need to exit the ongoing “unsustainability” of the privileged world. At the core of it lied the questioning of linear development when it comes to the future of the planet, examining economic growth in relation to social and ecological issues. At the same period, around the late 60s early 70s, not coincidentally the first works pointing to the emergence of environmental or ecological art made their appearance, within and outside the gallery space. Among them were land art pieces, like the "Spiral Jetty" of Robert Smithson and "Double Negative" of Micheal Heizer. From then until now, environmental art has evolved, has been enriched and has opened to different directions in accordance to each period. This workshop offers an overview of the field with examples of works by artists who have worked with matter and media in different ways, tacking not only how they discuss environmental topics but also how sustainable is the artworld itself.
