The wildly colorful buildings and paintings of the legendary Austrian artist and environmentalist Hundertwasser (1928–2000) are beloved across the world, and the subject of innumerable monographs. These works express a larger ethical vision that was always tied to his environmental activism, through writings that until now have perhaps been less well known than his architecture and buildings.

In numerous conversations, lectures, letters and manifestos, Hundertwasser formulated his ideas on recycling, green roofs and facades, and the democratization of living space. These texts are now collected in English for the first time. The title of the book alludes to Greta Thunberg’s Fridays for Future school strikes, as the urgency of Hundertwasser's ecological vision, considered by his contemporaries to be overly utopian, are now a matter of evident necessity.

Commemorating the 20th anniversary of Hundertwasser’s death, this attractive little book compiles his statements, excerpts from his manifestos, his paintings, examples of his utopian architecture and his ideas for the future.
