China is an environmental mess. Smog in Beijing is so bad it's literally broken the air-quality index. In Shanghai, it's at times turned the city into a scene from "Blade Runner." (It almost matches the infamous Cleveland smog of the 1970s.) Meanwhile, thousands of dead pigs -- cause of death not yet known -- have been floating down a river that cuts through Shanghai and provides part of the region's drinking water. More than half of China's water is so polluted, in fact, that even treatment plants can't make it safe to drink. And China is now responsible for almost half the world's coal consumption. That coal burning not only contributes to climate change -- it's also saddled China with severe cases of acid rain, something the United States dealt with a generation ago.
