China's environmental woes are mounting, and the country is fast becoming one of the leading polluters in the world. The situation continues to deteriorate because even when Beijing sets ambitious targets to protect the environment, local officials generally ignore them, preferring to concentrate on further advancing economic growth. Really improving the environment in China will require revolutionary bottom-up political and economic reforms.

China has become a world leader in air and water pollution and land degradation and a top contributor to some of the world's most vexing global environmental problems, such as the illegal timber trade, marine pollution, and climate change. As China's pollution woes increase, so, too, do the risks to its economy, public health, social stability, and international reputation. As Pan Yue, a vice minister of China's State Environmental Protection Administration (SEPA), warned in 2005, "The [economic] miracle will end soon because the environment can no longer keep pace."

...
The country is home to 16 of the world's 20 most polluted cities, and four of the worst off among them are in the coal-rich province of Shanxi, in northeastern China. As much as 90 percent of China's sulfur dioxide emissions and 50 percent of its particulate emissions are the result of coal use.

...
Yet coal use may soon be the least of China's air-quality problems. The transportation boom poses a growing challenge to China's air quality.

...
The Gobi Desert, which now engulfs much of western and northern China, is spreading by about 1,900 square miles annually; some reports say that despite Beijing's aggressive reforestation efforts, one-quarter of the entire country is now desert.

...
As Liu Quangfeng, an adviser to the National People's Congress, put it, "Almost no river that flows into the Bo Hai [a sea along China's northern coast] is clean." China releases about 2.8 billion tons of contaminated water into the Bo Hai annually, and the content of heavy metal in the mud at the bottom of it is now 2,000 times as high as China's own official safety standard. ... More than 80 percent of the East China Sea, one of the world's largest fisheries, is now rated unsuitable for fishing, up from 53 percent in 2000.

...
China is already the largest importer of illegally logged timber in the world: an estimated 50 percent of its timber imports are reportedly illegal.

...
China's Ministry of Public Health is also sounding the alarm with increasing urgency. In a survey of 30 cities and 78 counties released in the spring, the ministry blamed worsening air and water pollution for dramatic increases in the incidence of cancer throughout the country

...
Why is China unable to get its environmental house in order? Its top officials want what the United States, Europe, and Japan have: thriving economies with manageable environmental problems. But they are unwilling to pay the political and economic price to get there. Beijing's message to local officials continues to be that economic growth cannot be sacrificed to environmental protection -- that the two objectives must go hand in hand.
