     Restaurant owners should not use disposable chopsticks for the good of their health and the

environment, an official of the China Cuisine Association (中国烹饪协会) said.

     Bian Jiang, its secretary general, recently called on restaurant owners to say no to one-off tableware

(餐具), especially wooden chopsticks. "The country produces and throws away over 45 billion pairs of

wooden chopsticks every year, at a cost to the environment of about 25 million tree." Bian said.

      "That's a heavy blow to the county's shrinking forests," he said, "We should not turn a deaf ear to the

call for environmental protection. We should stop using disposable tableware from now on."
