Each year, the equivalent of 3.8 million trees go into the manufacture of about 57 billion disposable pairs of chopsticks in China, according to statistics from that nation’s national forest bureau. About 45 percent of disposable chopsticks are made from trees like cotton wood, birch, and spruce, while the remainder are made from bamboo.
Half of the disposables are consumed within China. Of the other half, 77 percent is exported to Japan, 21 percent to South Korea and 2 percent to the United States.
Chopsticks add to a plague of regional deforestation. According to a 2008 United Nations report, 10,800 square miles of Asian forest are disappearing each year, a trend that must be arrested to fight climate change, given the vital role trees play in absorbing carbon dioxide.
Activists argue that the disposable chopstick habit could gradually be phased out on an individual basis. Chopstick sets complete with a simple or decorative case are sold at many stores and are easy to put in a purse, knapsack or briefcase, they note.
In China, organizations like Greenpeace East Asia are trying to raise awareness of the issue. In December, 200 students from 20 Chinese universities collected 82,000 pairs of used disposable chopsticks from Beijing restaurants. With the discarded utensils, they built four trees, each 16 feet high, to create a “disposable forest.”
