The air quality in most of America's major cities, Los Angeles notwithstanding, is largely safe. However, within many major former industrial cities—especially those split along racial and class lines—there exist neighborhoods of largely lower-class black and Latino residents who are subject to far worse air pollution than many of their neighbors.

For instance, in Chicago, which has the highest amount of air particulates of any large American city, residents of majority-Latino neighborhoods Pilsen, Little Village, and the far Southeast Side have been fighting—with mixed success at best—against polluters and the city bureaucracies that have allowed them to pollute neighborhoods for decades. Far Southeast Side residents successfully got a Koch Industries-owned petroleum coke refinery to skip town and pay a settlement, but the settlement only amounted to some $60 per resident.

Seven of the 10 worst cities in America for air pollution are in California, per the American Lung Association. The two worst—Bakersfield and the Visalia-Porterville-Hanford metro area—are trending down. The two bear much of the attack that California's drought is waging on the state's air quality. Their location at the southern tip of the Central Valley, where the sun beats down unobstructed, creates an "inversion layer" of warm air, trapping industrial chemicals beneath it.

Why not purchase some lovely air from the Rockies, provided in "a convenient can" ($23.99 for "80 breaths of fresh air"). Or perhaps you'd prefer a jar of Welsh air, with "a morning dew feel to it, but enriched with vibrant and flavoursome undertones." A 12-pack of Australia's finest bottled air gets you Bondi Beach and Tasmania. All to service a growing market of people who live in polluted cities.
