On a little bit of a tangent, this article made me think about how far we've come in terms of air quality in Southern California. We can and should always do better. But in my high school years, we had up to 160 hazardous/very unhealthy air days in a year, and up to 305 mildly unhealthy to very unhealthy days that same year (1981). For comparison, in 2022, we had one hazardous/very unhealthy day, and fewer than 10 every year from 2007 on, with the exception of 2020. That actually inspires me when we see actual results from the efforts.
Look up images of LA pollution in the 1970s and 1980s. It was madness. And even with that obvious, visible soup we called air back then, there was extreme resistance to anti-pollution measures.
