Kristian Louis Jensen, an Inuit scientist, has spent a decade studying microplastic pollution in pristine Arctic environments using a self-built microplastic filter. His recent findings in eastern Greenland revealed that tire particles are contaminating remote glaciers, highlighting the global nature of pollution. Jensen emphasizes the need for better regulation of tire emissions and the formation of a scientific coalition to address the health impacts of microplastics on Arctic communities. His work will also be featured in an upcoming documentary.
