16、It is common to see disposable chopsticks used in restaurants. Many people like to use them because they think it is convenient to use them and they are clean.

As a matter of fact, they bring us more disadvantages than advantages. To begin with, it is a waste of wood. It is reported that a large quantity of trees are cut down to make chopsticks in our country every year, doing harm to the environment . Besides, disposable chopsticks are not clean at all because they are roughly made by small factories. So I think we should stop using them. The government should take action to prevent factories from producing such chopsticks and pay more attention to forest conservation.
