Pollution problems are growing in China. Smog in Beijing, captured in pictures and heavily reported, caught the world’s attention. Outdoor air pollution is now the fourth leading risk factor for deaths in the country, according to a report in The New York Times. But polluted water is another problem. In March, thousands of dead pigs were found floating in a Shanghai river, the main source of water for the city’s residents. Tainted waterways have been linked to higher cancer rates in people living nearby. Rivers filled with algae, garbage or turned unnatural colors by factory runoff and chemical spills are still being used by farmers, fisherman and for drinking water.
An official newspaper reported that China will spend 100 billion yuan ($16 billion dollars) over three years to deal with Beijing’s pollution. But will they address the water issue?
