In a surprise move that if enforced will lead to an undoubtedly cleaner Shanghai and China in general. The powers that be have decided that as of June 1st those ultra thin plastic bags (.025mm) that accompany virtually every purchase in China will be banned. The regular thickness plastic bags will still be allowed, but grocery stores and other vendors will be forced to charge for those bags and prices will need to be clearly marked.
Every year China refines 37 million barrels of crude oil to make three billion plastic bags. To put that into perspective, it would take Iceland about five years to use that much oil, but the USA would use that much oil in less than two days.
