The fulfillment of the UN Sustainable Development Goals (SDGs) is very much an issue about resources: How are resources articulated, created, and utilized? What is considered a resource, what exists in abundance, what is scarce, and when does something cease to be a resource? In our contribution, we address these issues with a focus on seaweed. By analyzing stories from environmental planners and ecopreneurs about seaweed, we demonstrate the phenomenon called resourcification — the social process that makes something a resource. From the stories, we illustrate the contexts of the resourcification and de-resourcification of seaweed. This allows us to show how resources, such as seaweed, are socially produced and become part of life. To conclude, we suggest that resourcification provides a provisional sustainability storyline suitable for working toward the SDGs in the Anthropocene.
