According to the World Health Organization, approximately what percentage of the world's population breathes air that contains health-threatening levels of particulate?

The World Health Organization (WHO) has reported that a significant portion of the global population is exposed to unhealthy levels of air pollution, specifically particulate matter. Approximately 70% of the world's population breathe air that contains health-threatening levels of particulate matter, which includes tiny particles that can penetrate deep into the lungs and even enter the bloodstream. This exposure is associated with serious health issues, including respiratory diseases, cardiovascular diseases, and negative impacts on overall health and well-being.

The statistic emphasizes the widespread nature of air pollution as a global health issue, highlighting the need for effective policies and actions to improve air quality in many regions around the world. This information is particularly relevant for environmental health specialists, as it underscores the importance of monitoring air quality and advocating for public health initiatives aimed at reducing particulate matter and protecting community health.
