Breathing Challenge: Unmasking Global Air Pollution

Air pollution affects 99% of the global population, causing 7 million premature deaths annually. Major pollutants include particulate matter and gases from burning fuels, threatening health worldwide. Air quality varies, and tools like AQI help monitor it. Limited protection methods include staying indoors, masks, and air purifiers.

Air pollution is a pervasive global issue, with 99% of the world's population exposed to harmful air quality that doesn't align with WHO standards. This exposure claims 7 million lives annually, primarily due to hazardous particles and gases from fuel combustion.

Air pollution's impact is particularly severe in cities like New Delhi, Jakarta, and Dhaka. Pollutants, from PM 2.5 particles to nitrogen dioxide, originate from diverse sources like vehicle emissions and agricultural practices. These pollutants pose significant health risks, including heart and lung diseases.

While tools like the Air Quality Index (AQI) offer insights into air conditions, they vary by region, complicating interpretation. Strategies to mitigate exposure include masks and air purifiers, but their accessibility remains limited in developing nations.
