Air pollution kills 600,000 children each year: WHO

Exposure to toxic air both indoors and out kills some 600,000 children under the age of 15 each year, the World Health Organization warned Monday.

Data from the UN health body shows that every day, 93 percent of children under the age of 15 - a full 1.8 billion youngsters, including 630 million under the age of five - breath dangerously polluted air.

This has tragic consequences: In 2016 alone, some 600,000 children died from acute lower respiratory infections caused by polluted air, the WHO report found.

"Polluted air is poisoning millions of children and ruining their lives," WHO chief Tedros Adhanom Ghebreyesus said in a statement.

"This is inexcusable. Every child should be able to breathe clean air so they can grow and fulfil their full potential."
