In the first half of the presentation, I’ll share my journey that began with marine debris and the aftermath of the 2011 tsunami, highlights the discovery of plasticizers in fish tissue and microplastics in fish guts and moves to the development of international measurement standards for microplastic sampling. The second half of the presentation will switch back to macro plastics, focusing on the necessity of source control to solve the plastic waste crisis and describe why granular transparency and accountability around the movement of waste materials is an essential part of source control, resource conservation and climate action.
