Pollution remains a critical concern worldwide, with alarming statistics highlighting its growing impact on health and the environment. According to recent studies, over 99% of the global population breathes air that exceeds the World Health Organization’s safe limits for pollution. Daily exposure to pollutants like particulate matter (PM2.5), nitrogen dioxide (NO2), and ground-level ozone (O3) have been linked to respiratory illnesses, cardiovascular diseases, and a significant reduction in life expectancy.
In cities, pollution levels often spike due to industrial emissions, vehicle exhaust, and urban development, creating an urgent need for immediate action. Monitoring daily pollution levels helps us understand the severity of this crisis, take preventive measures, and work towards cleaner, healthier air for future generations.
