NASA map illustrates air pollution mortality rates
''Want to know where people are most likely to die prematurely due to air pollution?
NASA recently recently released a map showing the average number of deaths per year per 1,000 square kilometers (385 square miles) that can be attributed to fine particle matter pollution.
Researchers compared pollution levels over a 150-year span, beginning in 1850 and ending in 2000. The dark brown areas on the map, shown prominently in Asia, India, Europe and parts of Africa, indicate locations with the highest rates of premature deaths due to air pollution.
Blue areas, as seen in the southeast United States and parts of South America, indicate areas that have seen air quality improve and the number of deaths due to air pollution decline.
Why are so many areas getting worse? According to NASA, that can be attributed to increased industrialization and urbanization. As to the areas in blue that have seen air quality improve from 1850 to 2000, researchers suggest that a decrease in biomass burning is the cause''
