This air pollution business is a bit unsettling. Is it really a problem?
The International Energy Agency estimated that Indoor and outdoor air pollution contribute to the deaths of around 18,000 people per day, worldwide. Air pollution—derived largely from industrial energy production and use—is linked to 6.5 million premature deaths annually. Clean air is needed for good brain-body health. “Yet despite growing recognition of this imperative,“ the Paris-based intergovernmental organization noted, “the problem of air pollution is far from solved in many countries, and the global health impact risks intensifying in the decades to come.”
