Plastic can travel hundreds to thousands of miles once it leaks into the environment. It’s found in every part of the world, and now about 170 countries have come together as part of the Intergovernmental Negotiating Committee (INC) to try and align national policies to curb the transboundary flow. At the current rate, plastic production would almost triple by 2060, with half of it landfilled, according to the Organization for Economic Cooperation and Development.
