China supplied its northern citizens with free coal for heating and cooking. That free-coal policy is now having an adverse effect: their life expectancy is being shortened.
The free-coal
policy was in effect north of the Huai River between 1950 and 1980, reports the
BBC and the Financial Times (July 9, 2013). Five hundred million people live in
the region. A 2013 study conducted by Chinese, American, and Israeli
researchers on air pollution and life expectancy reveals that the northern
residents have reduced their life expectancy by 5.5 years with higher rates of
heart and lung disease than the rest of China’s population. The air pollution
from burning coal in the area north of the Huai River was 55% higher than the
air quality in the south.
Researchers
studied the pollution levels and deaths in 90 cities in the north of China and
in the south between 1981 and 2000. The researchers focused on the total
suspended particles (TSP) in the air, such as soot and smoke. They also
analysed mortality statistics from 1991 to 2000 and found evidence of shorter
life expectancy in the areas that were previous under the free-coal policy. The
study published in the Proceedings of the National Academy of Sciences
indicated that there was an increase in the number of incidences of
cardio-respiratory deaths.
Therefore
while the provision of coal was aimed at keeping people warm and reducing the number of
winter related deaths from the cold weather and influenza, it was
counterproductive. The free-coal policy has had disasterous consequences for
the health of citizens.
