A draft of a 2007 combined World Bank and SEPA report stated that up to 760,000 people died prematurely each year in China because of air and water pollution. High levels of air pollution in China's cities caused to 350,000-400,000 premature deaths. Another 300,000 died because of indoor air of poor quality. There were 60,000 premature deaths each year because of water of poor quality.
The number of people living in water-stressed countries will increase from about 700 million today to more than 3 billion by 2025. (UNDP 2006, p.37). Every year 3 million people die prematurely from water-related diseases in developing countries.
