In 2025, cities like Manila, Delhi, and Jakarta rank among the world’s most polluted.
Nitrogen dioxide (NO₂) from traffic worsens asthma and heart disease.
Long-term exposure to air pollution reduces life expectancy by years.
Air quality worsens during El Niño events, trapping pollutants in the atmosphere.
Indoor pollution — from cooking or poor ventilation — kills millions yearly in developing nations.
Children are most at risk, as their lungs and brains are still developing.
Airborne microplastics are now being found in human lungs and placentas.
Green spaces and urban trees can absorb some pollutants and cool cities.
Governments are introducing low-emission zones and electric vehicle incentives.
Real-time air quality sensors empower citizens to monitor pollution levels.
Cleaner cities aren’t just healthier — they also save billions in healthcare costs.
