Nearly 2,000 children under five are dying every day from air pollution, which has overtaken poor sanitation and a lack of clean water to become the second biggest health risk factor for young children around the world.
More than 8 million deaths, of children and adults, were caused by air pollution in 2021, according to a new study from the Health Effects Institute (HEI), as both outdoor and indoor pollution continue to take an increasing toll on health.
