Factual communication alone is insufficient to raise awareness of marine microplastic pollution. An innovative drawing method called ‘eco-fabulous drawing’ has been developed through two groups of conceptual narrative drawing practices using eco-friendly techniques in a mixed-media installation: RADALAB 5: Is it Gold? and RADALAB 6: Are They Organisms? This cross-disciplinary practice integrates art, science, anthropology, ecocriticism, and storytelling. The research originates from empirical knowledge and experience gathered during fieldwork and studio practice at specific locations in Thailand and the United Kingdom between 2021 and 2024: Chao Phraya River, Bo Thong Lang Bay, Lune Estuary, and Rossall Beach. The method combines reliable scientific information, aesthetics, imagination, mythic elements, ecocentric perspectives, and philosophical insights to create attractive and accessible drawings that motivate and inspire audiences to think critically about the ecological crisis. The research demonstrates that drawing can serve as a multi-tool for addressing environmental problems and can be applied across disciplines, including noticing, communication, critical thinking, sympoiesis, storytelling, and ecological activity. Drawing expands its role as a bridge connecting various fields to communicate the issue of marine microplastic pollution. The findings also add evidence that land-based waste is a significant contributor to this pollution, supporting scientific research and environmental organisations concerned with this issue.
