Shopping bags, paper, or plastic? Each time we shop in supermarkets, we may ask ourselves such a question. Because both paper bags and plastic bags have their positive and negative impacts on the environment, even some environmentalists are bewildered by this simple choice. Experts say that paper bags are made from woods and plastic bags from crude oil. The plants consume 14 million trees or 12 barrals of crude to make the shopping bags American need in each year. The air polution resulted from making paper bags are 70% higher than that from making plastic bags. However, once made, plastic bags are difficult to degrade natually and they will exist for hundreds or even thousands of years.
