This article is pretty good at summarizing the importance of microplastic to health (downside), including in cardiovascular disease etc..
Global companies are trying to address this issue for a long time. The most recent development is Starbucks’ announcement of redesigned single-use cups with 10-20% less plastic.
EU’s objective: aims to reduce microplastic releases by 30% by 2030.
