Consider this: Consumers in China went through 57 billion pairs of disposable wooden chopsticks in 2009 alone, which equates to more than 3.8 million trees. For a nation that ranks 139th worldwide in forest land per capita, that means that China’s forests may be wiped out in 20 years if consumption continues at that rate.

Last winter Greenpeace East Asia and Ogilvy Beijing teamed with artist Yinhai Xu and students from 20 Chinese universities to stage a public awareness campaign. Together, they gathered some 80,000 pairs of used chopsticks from Beijing restaurants to assemble a “Disposable Forest” in a popular Beijing shopping center. The display urged people to carry around their own pair of chopsticks when eating out and asked them to sign a pledge to stop using disposable chopsticks. The 80,000 pairs of chopsticks that were transformed into four full-sized trees are a mere sliver of how many disposable chopsticks are used worldwide. Even though wood is a renewable resource is it really worth it to cut down a tree to make an eating utensil that is used once and thrown away?
