In 2017, Prime Minister Trudeau announced five themes for Canada’s G7 presidency which began in January 2018. Under the “Working together on climate change, oceans and clean energy” theme, Canada is hosting domestic and international discussions to advance priorities specifically focusing on oceans. These discussions will bring together experts to discuss challenges and opportunities both domestically and internationally, to move toward zero plastic waste and mitigating marine plastic litter, including microplastics ( Government of Canada, 2017). Global marine litter is now recognized as one of the most widespread sources of pollution facing the world’s oceans.
