During the pandemic I figured out that Covid and many other diseases spread through the air and could be minimized and contained with good indoor air quality methods. While I was far from alone in this understanding – I learned about it from some very smart people – those with the clout to make sure we improved air in every place from schools to public buildings to offices and other workplaces ignored or minimized the problem.
As a result, many of us still find it necessary to wear masks in a lot of indoor spaces, something that is not only annoying, but actually under attacks. Far too little has been done to improve indoor air quality despite the fact that the benefits go much farther than avoiding contagious diseases and include improved cognitive functioning and avoidance of health problems caused by chemicals trapped in poorly ventilated spaces.
So when I stumbled on Carl Zimmer’s book Air-Borne: The Hidden History of the Life We Breathe while browsing in a bookstore, I was intrigued. I knew Zimmer was a science writer for The New York Times, and the book seemed to have thorough reporting.
What convinced me to buy this thick book in hardback rather than wait until it was available in the library was the blurb from Ed Yong, who called Zimmer “one of the very best science writers” and noted that the book would leave readers “agog at the incredible world that floats unseen around us and outraged at the forces that stopped us from appreciating that world until, for many people, it was too late.”
I almost never buy books based on blurbs, but since Yong is a brilliant science writer and a man of fierce integrity when it comes to his profession, I had no doubt that he was giving his honest opinion.
And he was right. Air-Borne is a superb book that shows deep research into the history of the things that float in our air – much more than viruses – and of the people who have struggled to show us that we need to pay attention to what we’re breathing.
I was already outraged before I read it, but looking at the history increased my fervor. So many scientists came up with valuable clues to how viruses, bacteria, and fungi spread through the air only to be pushed aside or overlooked.
The book starts with a 2023 concert by the Skagit Valley Chorale, the choir in Washington state that experienced a super-spreader event that left two people dead after they met to rehearse during the early days of the pandemic. The number of people infected at that rehearsal was one of the things that made people realize this virus was air-borne.
Zimmer was at that concert with a CO2 meter in his pocket, trying to gauge if he needed a mask. As someone who often travels with a CO2 meter, since the amount of CO2 in the air gives you a good idea of the ventilation in a space, I recognized a kindred spirit.
