Train tracks lead to a plant in the Bao Steel mill, Inner Mongolia, China. Baotou is an excellent example of being a one-industry town, and that industry is steel. Baotou is also notorious as a big polluter mostly from the large Bao Steel factory. With Baotou sitting directly west of Beijing much of Beijing's notorious smog and haze comes from cities such as Baotou, which lay directly west. With the economic stimulus package that was just earmarked for infrastructure and housing you can bet China's environmental goals have been put on hold for the foreseeable future, the residents of Baotou may not mind at all, but what about Beijing.
