WHO: 92% of The World Is Breathing In Excessive Air Pollution

The World Health Organization says nearly everyone in the world is breathing in polluted air. A new WHO air quality model shows 92 percent of the world's population lives in places where the air quality exceeds WHO limits. WHO officials say 90 percent of air-pollution-related deaths happen in low or middle-income countries.

WHO hopes to lower those dangerous air pollution levels through BreatheLife. BreatheLife is a worldwide communications campaign aimed at increasing public awareness of air pollution and its risks.
