SHELLEY STREEBY, "Octavia E. Butler’s Ecological and Environmental Worldmaking: Dune, Disaster, Bag." Drawing on Butler’s papers at the Huntington Library, I situate struggles over environments and ecologies as central to Butler’s memory-work and worldmaking throughout her life. The word environment had multiple meanings for Butler, including the worldmaking involved in creating science fiction and fantasy’s secondary worlds; the earthly environments that formed and inspired her; learning environments such as libraries, schools, and workshops; environmental racism and environmental movements; and environmental and ecological speculation on respecting relations and responsibilities to the more-than-human world as opposed to short-term thinking and policy-making intensifying extraction and environmental destruction. I reconsider three environmental and ecological keywords in the light of Butler’s memory-work and speculation: "Dune," "Disaster," and "Bag."
