Until August <a href=" http://ornithology.com/the-canary-bird/ ">tongue pearls viagra barato online dangers</a> The study by West and his colleagues comes on the heels of another recently published study finding a strong correlation between air pollution caused by burning coal and a significant reduction in life expectancy. In that study, published in the Proceedings of the National Academy of Sciences, researchers compared populations living in northern and southern China and found that people in the north, who generally depend on coal for their heating requirements, are likely to die more than five years sooner than those living in the less polluted south. Researchers also concluded that every additional 100 micrograms of particulate matter per cubic meter in the atmosphere reduces an infant芒聙聶s life expectancy by three years.
