Pollution, rather than weather, is the far greater problem, particularly in Beijing, Shanghai and Xi’an. China is home to 20 of the world’s 30 most polluted cities. Only 1% of China’s 560 million urban residents breathe air that is deemed safe by European Union standards.
750,000 people in China die prematurely each year from pollution – mainly from air pollution in large cities—according to a World Bank 2007 report, “Cost of Pollution in China“.
