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.
Polluted water is water that is not safe and not healthy for people and animals to drink or to wash in. Polluted water is particularly dangerous to water plants and animals. Polluted water is also particularly dangerous to people who get their water directly from a river or dam.
