This level of clean city air\u2014clean enough to breathe freely without fear of eventually\u00a0 damaging one\u2019s health and that of one\u2019s children, is unprecedented in the modern era. Urban residents have marveled at the clarity of distant mountains rarely seen or imagined.

The air pollution in London, England, has been atrocious since the 17<sup>th<\/sup>\u00a0Century when the poet Sir William Davenport complained about the \u2018canopy of smoke\u2019 that covered the city.\u00a0 We might have imagined that London\u2019s air quality had improved over the last three centuries as the burning of coal in the city has been replaced by cleaner fuels, but we would be wrong. A report released in 2017 found that all Londoners are exposed to concentrations of particulate matter higher than WHO air quality guidelines. In central London, about 8 million people breathe in air that exceeds the guidelines by a whopping\u00a0<a href=\"https:\/\/www.theguardian.com\/environment\/2017\/oct\/04\/revealed-every-londoner-breathing-dangerous-levels-of-toxic-air-particle\">50 percent or more.<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The last ICE age<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Coal is no longer the primary culprit.
