Air pollution caused the premature deaths of 600,000 children in 2016, according to a World Health Organization (WHO) report released Monday. The report found that a staggering 93 percent of people under 15 years old—some 1.8 billion children and teenagers—are breathing toxic air.

“Polluted air is poisoning millions of children and ruining their lives,” WHO director-general 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.”
