请阅读下面短文,从每小题所给的 A、B、C 三个选项中选出一个最佳选项。
In the United States, a question is asked millions of times every day in the supermarket: “Paper or plastic?” Well, which kind of bag would you choose?
In fact, all kinds of bags have some influence on the environment. But we are always told that paper bags are better. For example, they break down easily and can be recycled. However, the producing process behind paper bags uses more energy than that of plastic ones. How can this be true?
Studies show that paper bag production requires four times as much energy as plastic bag production. And the amount of water used to make paper bags is twenty times higher. Besides, the influence on forests is more serious. It takes about fourteen million trees to produce ten billion paper bags. As for recycling, some people believe that paper bags are more environmentally friendly than plastic ones. However, this idea can be quickly discarded. Research shows the opposite is true.
Even though paper bags might be more harmful than plastic ones, plastic still seems to be considered by governments to be the more harmful of the two. In Ireland, people have to pay 22 cents for every plastic bag, and as a result, their use has dropped quickly.
It seems wise to reuse these bags. However, we’re not doing that much. That may be because they are easily broken. If so, cloth bags are a better choice, but still, their production also has a bad influence on the environment. So what should we do? How should we answer the question, “Paper or plastic?” It seems that we first need to ask ourselves the following question: “What can I do to help the environment?”
