Nine out of 10 people around the world are exposed to toxic levels of air pollution, and 7 million people each year die of conditions related to air pollution, according to the World Health Organization. "I'm afraid what is dramatic is that air pollution levels still remain at dangerously high levels in many parts of the world," says Maria Neira, director of WHO's Department of Public Health, Environmental and Social Determinants of Health.
