United Nations agency the World Health Organization just released it's third Global Urban Ambient Air Pollution Database with bad news for pretty much everyone on the planet. The facts are stark: air pollution causes more than 3 million deaths around the world each year. But, if the dust clears, will climate change accelerate?
The Global Urban Ambient Air Pollution Database compares 795 cities in 67 countries, looking at the levels of what is called fine particulate matter over the period from 2008 to 2013. The study was confined to those areas that monitor air pollution on an ongoing basis.
Air pollution is measured in terms of the number and concentration of microscopic particles (or particulate matter) in the air. Those particles are composed of substances such as sulfur, black carbon and nitrogen oxides. The tiny particles can enter right into the lung tissue as you breath them in. They are known to contribute to many diseases and conditions such as asthma, heart disease, and stroke.
The amount of such particles has increased a full 8 percent, overall, in the 5 year period from 2008 and 2013.
