    Limiting The Use of Disposable Plastic Bags
    Disposable plastic bags were once widely used in China. When we went shopping at supermarkets and departments stores， shopping assistants often provided free plastic bags for our convenience. For a while， life without them seemed
    However， disposable plastic bags do bring severe damage to our environment. Costumers usually threw them away after use， and because they are thin and hard to decompose， these plastic products will exist for a long time. This is an immediate threat to our earth and water.
    Nowadays， the government has passed relevant regulations for limiting the use of disposable plastic bags： they are not free any more. In some shopping places， in order to invoke the public awareness of environmental protection， plastic bags are offered in a much higher price. As a result， people are changing their behavior： paper and clothing bags that vanished for a long time come back to our daily life. It is true that by limiting its usage， everyone in this society contributes some effort to the improvement of the environment.
