So how to draw inspiration from this speculative shift to a “Homo Photosyntheticus”? Margulis and Sagan envisioned it as enabling humans to become multi-planetary. The European Space Agency’s MELISSA (Multi-Ecological Life Support System Alternative) program is considering circular systems for life on other planets, imagining the cultivation of spirulina as an alternative food and oxygen source. The Multicellular Marine Models aboratory at the Roscoff Biological Station is planning to study the Roscoff worm in space to better understand its photosymbiotic life cycle and its tissue regeneration capacities. Why? Perhaps because we still only know far too little about the oceans, the planetary holobionts and the life of algae, these protists that are “queering” conventional taxonomy. Is the objective to go from the ocean floor to outer space and back to Earth, the ocean planet? To finally leave the Anthropocene and enter this Chthulucene that the philosopher and zoologist Donna Haraway is calling for?
These few words summarize the artistic research topics we have been exploring and expanding upon since 2021 in various forms: writing, videos, workshops, conferences, installations, art objects and performances. They are also nourishing a creative documentary now being made. This research through writings and videos lead to: interviews with artists Špela Petrič and Robertina Šebjanič, art collective Quimera Rosa, scientists from the European Space Agency’s MELISSA program, and professor Hideo Iwasaki, director of the metaPhorest bioaesthetics research platform at the University of Waseda in Tokyo, as well as a film journal on the memorial to Kathleen Drew-Baker in Kumamoto, on Kyushu island, Japan.
