Its production is a barbaric act of plunder, its storage and transportation is accompanied by unavoidable pollution, and its use is clearly unclean and wasteful.

A tree that has grown for 20 years can only make 6,000-8,000 pairs of chopsticks. China produces 10 million boxes of disposable chopsticks every year, of which 6 million boxes are exported to Japan, South Korea and other countries. The Japanese invented disposable chopsticks, but they were not produced in the forests of their own land, and they were used for papermaking and so on.

China's forest coverage rate is less than 1 4 of Japan's, and the annual forest stock for the production of disposable chopsticks is reduced by 2 million cubic meters. Therefore, we advocate refusing to use disposable chopsticks when eating out, and refusing to use wooden pencils in daily study and work.
