Each day, 1.8 billion children breathe air that is so polluted that it jeopardizes their health and development. 600,000 children died in 2016 as a result of acute lower respiratory infections caused by polluted air. The World Health Organization has released a new report titled “Air pollution and child health: Prescription for clean air examines the severe toll that both ambient (outdoor) and household (indoor) air pollution take on the health of the world’s children. The report is being launched on the eve of the World Health Organization’s first-ever Global Conference on Air Pollution and Health, which will take place at the World Health Organization’s headquarters in Geneva from 30 October to 1 November 2018.
