92 percent Of The World’s Population Is Breathing Polluted Air.

More than 92 percent of the world’s population is breathing polluted, unsafe air and the hardest hit areas are in Africa and Asia, a major study of global air pollution has found. Urban areas, which are home to a greater percentage of the world’s population than ever before, are exposing hundreds of millions to air that is filled with pollution from automobiles and factories. In many rural areas, the burning of solid fuels like wood, charcoal and coal, is also a threat. The report, known as the State of Global Air and produced by the Health Effects Institute, analyzed satellite data and other air-quality monitors to figure out what percentage of the world is exposed to air polluted above levels that the World Health Organization deems as safe.
