Wildfires kill 339,000 people per year: study
Vancouver (AFP) Feb 18, 2012
Wildfires, peat fires and controlled burns on farming lands kill 339,000 people worldwide each year, said a study released on Saturday that is the first to estimate a death toll for landscape fires. Most of those deaths are concentrated in sub-Saharan Africa, where an estimated 157,000 people die as a result of being exposed to such fires annually, with southeast Asia ranking second with 110,000 deaths. "I was surprised at our estimate being so high when you consider that the exposure to fire sm ... read more
