Greenstone, who co-directs the Climate Impact Lab and spent a year working on climate policy in the Obama White House, introduces the Air Quality Life Index — a satellite-data tool that calculates how much longer people would live if local pollution met WHO standards. The answer is striking: 2.2 years per person on average globally. [2] — Michael Greenstone "Average life lost to pollution: 2.2 years: Michael Greenstone's Air Quality Life Index estimates the average person on Earth lives 2.2 year…" 07:26 The WHO estimates roughly 7 million people die every year from fine particle exposure — more than double COVID deaths in 2020 and more than five times annual car-crash fatalities. [1] — Michael Greenstone "It's worse than cigarette smoking. It's worse than wars. It's worse than auto accidents." 07:40 The economic cost is estimated as high as $6 trillion per year, about 5% of global GDP. Greenstone's framing sets the episode's central tension: we know pollution is catastrophic for physical health, but have we been systematically ignoring its effects on the brain?
