Pollution problems are becoming more and more serious. One of them is called “white pollution” caused by plastic, such as shopping bags, boxes and cups. In China about three billion plastic shopping bags are used every day, which results in a great waste of resources （资源） and heavy environmental pollution. Luckily, the government has stopped us from using free plastic bags, telling all stores and supermarkets not to provide customers（顾客） with free plastic bags since June 1, 2008. From then on, people have been supposed to use cloth bags and shopping baskets instead of plastic bags in order to protect our environment.
Now more and more people have realized the importance of using the cloth bags and the shopping baskets. For one thing it can protect our environment, for another it can also make our country cleaner and more beautiful. Yet we have much more things to do to solve the problem of “white pollution”!
