The U.N.`s New Warning About Air Pollution
First up, the World Health Organization, part of the United Nations, has a new warning out about air pollution. It says that nine in ten people around the world live in areas with unsafe levels of pollution. The organization collected data from thousands of locations worldwide and says air pollution contributes to more than 3 million deaths every year.
Poor air quality is one reason why you see people wearing face masks in some Chinese cities. Pollution in China is said to factor in to more deaths per year than in any other country.
But India also has a high death toll blamed on air pollution, followed by Russia. And the World Health Organization says air pollution increases the risk of stroke, hearth disease, respiratory infections and lung diseases including cancer.
The report measured pollutants like sulfates, nitrates and black carbon, blamed for getting into people`s lungs. It said that the vast majority of air pollution related deaths occurred in low and middle income countries. As far as the U.S. goes, the WHO estimated that air pollution was tied to more than 38,000 deaths in 2012.
Solutions: the WHO suggests clean forms of transportation, better management of garbage, better cooking stoves in poor countries, and more renewable energy. But it said human activity wasn`t the only cause of pollution. Natural events like dust storms and areas near deserts also pollute the air.
