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“. An estimated 350,000-400,000 people died prematurely from outdoor air pollution and an additional 300,000 died from indoor air pollution, such as the fumes from the coal-burning stoves.
Almost a third of San Francisco’s air pollution comes from China.
