Companies have spent decades obstructing efforts to take on the plastics crisis and may have breached a host of US laws, a new report argues. The research from the Center for International Environmental Law (CIEL) details the widespread burdens that plastic pollution places on US cities and states and argues that plastic producers may be breaking public nuisance, product-liability, and consumer-protection laws. It comes as cities such as Baltimore have begun to file claims against plastic manufacturers, but the authors write that existing cases “are likely only the beginning, as more states and municipalities grapple with the challenges of accumulating plastic waste and microplastics contamination.” Taxpayers foot the bill to clean plastic pollution from streets and waterways, and research shows people could ingest the equivalent of one credit card’s worth of plastic per week. “We’re in the midst of a population-scale human experiment on the impacts of multigenerational toxic exposures,” said Carroll Muffett, president of CIEL and a report co-author.
