People should not be encouraged to use plastic bags.

Plastic bags are very popular in our daily life. People go shopping with plastic bags in free markets, super markets, or departments.

But plastic bags are one of the major pollutants. We can see littered plastic bags thrown everywhere, especially along the railways or highways, in the parks or in the rivers. Because plastics is not degradable, once it is thrown in the environment, it will exist for a long time and pollute soil and water. They are even dangerous to wildlife as thousands of sea animals are killed each year when they eat or are chocked by plastic bags. What¡¯s more, ¡°white pollution¡± creates a bad image for China.

So Government should make law to forbid the use of plastic bags in department stores and supermarkets. Meanwhile, people should be encouraged to replace them with paper bags or cloth bags.
