That is the theme of my latest Bloomberg column, here is one excerpt:

More than 10 million people die each year from air pollution, according to a new study — far more than the estimated 2.6 million people who have died from Covid-19 since it was detected more than a year ago. And while Covid is headline news, ordinary air pollution remains a side issue for policy wonks and technocrats.

[To be clear, I am not seeking to minimize Covid as a major issue.]  And:

Why aren't these deaths a bigger issue in U.S. political and policy discourse? One reason may be that 62% of those deaths are in China and India. The number of premature deaths due to particulate matter in North America was 483,000, just slightly lower than the number of measured deaths from Covid to date. An estimated 876 of those deaths were of children under the age of 4.

Another reason for the weak political salience of the issue may be its invisibility. Air pollution causes many deaths. But it is rare to see or read about a person dying directly from air pollution. Lung cancer and cardiac disease are frequently cited as causes of death, even though they may stem from air pollution.

Another problem is that the question of how to better fight air pollution does not fit neatly into current ideological battles. You might think Democrats would emphasize this issue, but much of the economic burden of tougher action would fall on the Northeast, a largely Democratic-leaning area.

And exactly how many people die each year from global warming?  Why not have a greater focus on ordinary air pollution?
