Asian environmental correspondent for the Guardian, Watts travels to the four corners of China, from the southwest Himalayan region, rebranded as “Shangri-la” to attract tourists, to Xanadu (Shangdu) in Inner Mongolia, exploring how Beijing is balancing economic growth with sustainability and whether China will “emerge as the world’s first green superpower” or tip our species “over the environmental precipice.” What he finds is both hopeful and disturbing. Wildlife refuges, rather than focusing on biodiversity, breed animals for meat and traditional remedies like black bear bile. The city of Ordos plans to build a huge wind farm and solar plant, but these benefits are offset by its coal-liquification mine, “an environmentalist's worst nightmare” of greenhouse gases and water exploitation. The Chinese dictatorship, envied by other nations for its ability to enact environmental changes without the slow democratic process, turns out to be ineffective, with power lying with developers and local bureaucracies. Readers interested in global warming will appreciate the firsthand information about China, and Watts’s travels are so extensive and China is changing so fast, some material is likely to be fresh and new even for Sinologists.
