Joel at Far Outliers usually posts excerpts from books and articles that are not otherwise readily available online. He has a very good eye, so his blog is worth reading just for that.

However, a few weeks ago when I wasn't looking, he started posting pieces of his own writing from twenty-odd years ago when he was teaching English in the PRC. It makes for fascinating reading. Back then, despite Deng Xiaoping's gingerly moves toward liberalization, most Americans didn't get much information about China. The multi-part documentary The Heart of the Dragon, which aired on PBS in the States, was about as good as it got. (Things were similar with the Soviet Union--anyone else remember watching the "Comrades" series on Frontline?)

One thing that caught my attention was a passage from this post:

In China those who have tap water don't drink it. Almost all the water and tea consumed each day by one billion Chinese goes through a kettle and thermos bottle first.

There must be at least a billion thermos bottles. If each thermos bottle is emptied twice a day, then four billion liters of water pour out of the mouths of thermoses each day.

Boiled water is the universal cleanser. Diners in China's typically grimy eating places often rinse their tableware with hot water or tea before they eat or drink anything. Some roadside eateries reassure their customers by bringing out all the tableware in a large soup bowl full of scalding water. The customers can rinse everything themselves.

Disposable eating utensils, like disposable medical supplies, are just coming into use in China. A recent China Daily letter to the editor lauded the growing practice of providing disposable chopsticks in restaurants in Beijing.

How times change. By 2000, disposable chopsticks were ubiquitous in China and had started to draw fire because so many trees were being cut down to make them. Last year, the PRC started putting taxes on them:

The disposable splints of wood, usually between eight and 10 inches long, have long been a target for Chinese environmentalists.

...

In recent years, the government has actually encouraged their use, in a bid to reduce the spread of infectious illnesses by sharing eating utensils.

A lot of China's product has been exported here to Japan; I read somewhere years ago that over 90% of the disposable chopsticks consumed here came from the PRC. It's been proposed that such exports be banned as early as 2008.

Perhaps China has reached a stage at which the tradeoff involved in not making disposable chopsticks freely available in order to preserve the environment is a good one. It's worth noting, though, that (as both Joel and the BBC mention) single-use utensils help close one path through which communicable diseases spread, which was no mean consideration in crowded, developing China.

Be sure to read Joel's other posts, too.
