If an environmental impact report is certified, it's likely that Marin County, Calif., will ban the use of plastic bags and impose a fee on paper bags beginning next year. According to the California Supreme Court, "Plastic bags have no recycling market. It takes 500 years for them to decompose. And they have created a major solid waste issue for Marin. It was therefore a reasonable legislative and regulatory choice for Marin County, after years of study, to ban plastic bags while imposing a fee on paper bags."
