Marine plastic pollution is an issue that threatens most places around the world, including the remote and unique Galapagos archipelago. We used the archaeological framework of object itineraries as part of a story-writing workshop to explore perceptions of marine plastic litter (MPL) by students from two schools in Puerto Ayora, Santa Cruz. Their stories, adopting an archaeological approach to plastic litter as artefacts, told the itinerary of MPL collected on Galapagos shores. We also analysed surveys evaluating their self-reported knowledge, pro-environmental behaviours (PEBs) and perceptions of the issue of MPL before and after the workshop. Our findings showed good awareness of MPL origins and impacts, reflecting the specific pathways of litter reaching this Pacific archipelago from mainland South America, regional marine activities including fishing in and around the Galapagos Marine Reserve, and local sources, although those are thought to be limited. Yet the lack of focus on solutions in the stories and the emphasis on recycling PEBs suggest more targeted activities are needed to address the need of complementary solutions and to place more emphasis on reducing plastic use.
