Air Pollution
Roughly 7β8 million premature deaths a year β more than malaria, HIV and traffic accidents combined

π§ Understand
The trend
Rich countries and China have cut particulate pollution substantially; South Asia and household smoke remain severe. This problem is dramatically underfunded relative to its death toll.
The scale
Fine particles (PM2.5) from vehicles, industry, crop burning and indoor cooking fires cause on the order of 7β8 million early deaths a year (WHO-linked estimates) β heart disease, stroke, lung cancer, child pneumonia. ~99% of humanity breathes air exceeding WHO guidelines.
Root causes
Fossil fuel combustion, crop-residue burning, and roughly 2 billion people cooking on smoky solid fuels indoors β making this problem a twin of both climate and poverty.
Who suffers most
City dwellers in South Asia (Delhi's air can cut years off life expectancy), women and children near indoor cooking fires, and the unborn β pollution affects birth outcomes.
Common misconception
"Air pollution is an unfortunate nuisance, not a top killer." It kills roughly 10Γ more people than all wars and murders combined each year, yet receives a sliver of health funding and attention.
β‘ What actually works
Emission standards & enforcement
Strong evidence
Vehicle, power-plant and industrial standards β the policies behind every clean-air success story.
Cost & effect: The US Clean Air Act's benefits are estimated at ~30Γ its costs; China cut PM2.5 ~40% in under a decade by decree.
Clean cooking transition
Promising
LPG, electric or improved stoves replacing indoor solid-fuel fires.
Cost & effect: Tens of dollars per household per year; health effects depend on how completely smoky fuels are displaced.
Monitoring & open data
Promising
Cheap sensors and public dashboards that make invisible air visible and create political pressure.
Cost & effect: Very cheap; repeatedly a trigger for policy action.
π§ Act
πΆ With your money
