Do you often like to use disposable（一次性的） chopsticks when eating out? It’s time to drop this habit.

China products（生产） 80 billion pairs of disposable chopsticks every year. “This is enough to cover Tian’anmen Sqaure 363 times,” said Bai Guangxin, chairman of Jilin Forest Industry Group, at the National People’s Congress on March 8.

The government has made some rules to limit（限制）the use of disposable chopsticks. However, there are still many being produced.

“The production of such chopsticks is a heavy burden on national forests,” Bai added. A total of 20 million 20-year-old trees would have to be cut down to make way for this annual production.

Bai called on people to bring their own chopsticks whenever they are eating out. “We first need to bring a change to people’s eating habits and encourage everyone to carry their own chopsticks around.” He also said that there may be technology that can turn wild grass into disposable chopsticks in the future.
