World Air Quality Index 2023
More than 76 percent of India’s population lives in places where the national ambient world air quality index limits are permanently exceeded. On the other hand, people have yet to demand clean air from their elected officials and representatives.
As a result, it has never made it into the mainstream political agenda or the public conversation during any election or political campaign. In 2019, a few political parties included it in their election manifestos for the first time, marking a significant step forward.

Air contamination kills approximately a million people per year, accounting for 17 percent of all fatalities in the United States as a direct or indirect effect of the pollution. Those with higher educational levels are similarly affected by the pollution. Academics and experts spend a lot of time discussing abstract concepts like air quality index and economic efficiency.
Air pollution and its impact
The combustion of fossil fuels is the primary source of air pollution. The most significant contributions are fossil-fuel-powered vehicles (cars, trucks, airplanes, ships, and other similar vehicles) and coal- or oil-burning power plants and industries.
Any action that includes the burning of wood or fossil fuels, on the other hand, has the potential to emit particulate matter. It includes sources found in the home, such as tobacco products, stoves and ovens, candles, and fires, among other things. Volcanoes and wildfires are both known to be significant contributors to air pollution.
Air pollution contributes to various health concerns, including breathing difficulties, asthma flare-ups, and congenital disabilities. Globally, toxic contamination, according to various sources, is one of the most significant risk factors for noncommunicable diseases (NCDs).
Noncommunicable diseases account for 72 percent of all fatalities, with toxic pollution accounting for 16 percent of all deaths caused by toxic pollution. It is estimated that toxic pollution is responsible for 22% of all cardiovascular disease fatalities, 25% of all heart attack deaths, 40% of all lung cancer deaths, and 53% of chronic obstructive pulmonary disease deaths.
