I will tell you the truth about plastic bags－the positive and the negative sides and provide a solution to this problem. Whether it is a shopping bag, a food bag or a trash bag, they are all made of plastic bags. Grocery store owners are very generous in using plastic bags.

Plastic bags are produced so cheaply and massively（大量地）that they are used by 80% of store owners. In addition, they are light and very easy to carry and store. The production of plastic bags has increased greatly over the last 20 years and producers of plastic bags are making large profits. However, the negative side of plastic bags is becoming well-known. More people are now getting worried that the earth is becoming a victim of the plastic bag success story. The negative side of plastic bags While production and consumption（消费）of plastic bags is good for business, it is not so for our Mother Earth. They have resulted in an increase in the amount of litter found floating in water or in the streets where we live. Plastic storage bags, after usage, usually go to landfills（垃圾填埋地）as trash bags.
