Urbanisation and health in China (10 page pdf, Peng Gong, Song Liang, Elizabeth J Carlton, Qingwu Jiang, Jianyong Wu, Lei Wang, Justin V Remais, The Lancet, Mar. 3, 2012)
Today we review the state of the environment and health in the most quickly growing (and largest) cities in the world that have come about because of a massive shift from rural to urban areas where migrants make up 40% of the population. A major health threat comes from the parallel increase in industry and increase in the use of vehicles which affect outdoor air quality and is the cause of 400,000 premature deaths each year which becomes even more critical in a society that is aging faster (and is older) than the global average (by 2050, median age expected to be 50 vs 38 years). The paper under review calls for more stringent regulation of industrial and vehicle emissions.
