A recent report reveals that nearly every country has air quality worse than recommended by doctors, with only seven nations meeting the WHO's PM2.5 guidelines in 2024. While the most polluted nations like Chad and India exhibited PM2.5 levels significantly above safe limits, some progress was noted, such as a rise in cities meeting standards from 9% to 17% and a reduction in pollution levels in India. Experts warn that PM2.5 poses severe health risks over decades, emphasizing preventive measures for better public health outcomes.
