Air Pollution in Canada
According to the World Health Organization, more than 80 percent of people living in urban areas around the world are exposed to air quality levels that exceed WHO guidelines. With air pollution, also comes an increased risk of heart disease, stroke, lung cancer and respiratory diseases such as asthma. While Canada is far down the WHO offender list (it’s actually third in the world for best air quality) many Canadian cities are still listed at risk for health-related issues from poor air quality. The Canadian Medical Association estimates that poor air quality was responsible for 21,000 deaths in 2008. Three cities in Canada exceeded the maximum level for particulate matter per cubic metre.
