the problem of “white pollution” caused by used plastic is becoming increasingly serious, in which plastic shopping bags play an important role. in china about three billion plastic shopping bags are consumed every day, which results in a great waste of resources and heavy environmental pollution. luckily, the government has put a nationwide ban on the use of free plastic bags, demanding that all stores and supermarkets not provide customers with free plastic bags after june 1. the rule will undoubtedly reduce the use of plastic bags and enhance the awareness of environmental protection. it is highly advocated that we should turn
to cloth bags and shopping baskets from now on.
