The US didn't always have the clean air many of us are used to.
This week I didn't expect my texts to be about air quality.
New Yorkers and others are getting a taste of what it can be like to live in Doha, Qatar, and Shanghai, where at least air pollution appears to be improving.
When the first Earth Day took place in April 1970, air pollution was a major problem in most US cities.
Those actions have since made such a difference that many of us are now shocked by what poor air quality looks like.
