Air pollution is one of the biggest threats the world is facing. Every year thousands of people die because of toxic air. Recent report from Unicef is highlighting the same issue.

Around 300 million children in the world are breathing highly toxic air reports, Unicef.  Most of these numbers came from South Asia.

Unicef further reports, almost one in seven of the world's children live in areas where the level of toxic level is six times higher than the international guidelines. The implication of this problem is severe as every year, around 600,000 children under the age five die due to air pollution.

South Asian region including India and neighboring countries are the most affected. Satellite imagery is used to get these results and to know the numbers of children exposed to outdoor pollution. The satellite imagery confirms South Asia, Africa and pacific region are hit by the toxic air. According japantimes, New Delhi is one most the most air pollution in the world.

Outdoor and indoor air pollution is the cause of serious health problems especially related to heart. It causes respiratory disease, pneumonia and in some cases even cancer. The most dangerous air particles are PM2.5. These particles are released from dust, fossil fuel, industry and from vehicles smog.

Pollution is the long standing and the biggest threat the world is facing today. Many countries are trying to cut down its carbon emission. At COP 21 the developing many countries pledged to decrease the carbon emission. Unicef will urge the world leaders to take serious action and cut down the air pollution at COP 22 in Marrakesh,Morocco. China's capital Beijing and India's capital New Delhi are the most polluted cities in the world.  

If the problem continues, the consequences will get worsen.
