Good morning. It's Monday, March 25. I'm Christian Orozco, an editor on the newsletters team. Here's what you need to know to start your day.
California's unflattering achievement
You are tired of the city and the traffic. You're looking to break away from the expanding industrial facilities encroaching on open spaces. So you drive up to Sequoia and Kings Canyon National Parks.
Congratulations, you've made it to the most polluted parks in America.
Sequoia and Kings Canyon topped two lists in the National Parks Conservation Assn.'s report on polluted parks, "National Parks With Unhealthy Air" and "Worst National Parks for Hazy Skies," my colleague Lila Seidman reported. Joshua Tree, Mojave, Yosemite and Death Valley were also ranked in the top 10 on the unhealthy-air list.
The report called Sequoia, Kings Canyon, Joshua Tree and Mojave "the most ozone-polluted national parks in the United States," with the ozone layers being "significant concern for human health."
Wildfire smoke has left California parks worse off than parks in other states
Although California parks join the rest of the nation in the fight against threats related to climate change, the Golden State is also disproportionately affected by wildfires, Seidman reported.
Sequoia and Kings Canyon National Parks took the No. 1 position partly because of the 2020 Castle and the 2021 KNP Complex wildfires. (They also took the No. 1 position the last time the report was published, in 2019.)
According to the report, the fires destroyed "tens of thousands of acres and numerous sequoia groves within the parks." The destruction of sequoias "not only threatens the regeneration of the iconic trees but also disrupts ecosystems and harms wildlife within these parks." It added that "19% of the world's mature giant sequoias may have been lost due to wildfires." California's Joshua trees have suffered a similar fate in the face of the state's wildfires.
Pollution from population and industrial centers also affects our parks
Seidman wrote that "car-dependent population centers such as Los Angeles; agricultural and industrial operations in the San Joaquin Valley; trucking and warehouse facilities in the Inland Empire; and the ever-buzzing ports complex in Los Angeles and Long Beach" are what have made California parks dirtier.
Half of the 10 parks with the unhealthiest air are in California. Here they are:
- Sequoia & Kings Canyon (Calif.)
- Joshua Tree (Calif.)
- Mojave (Calif.)
- Yosemite (Calif.)
- Carlsbad Caverns (N.M.)
- Death Valley (Calif.)
- Indiana Dunes (Ind.)
- Guadalupe Mountains (Texas)
- Rocky Mountain (Colo.)
- White Sands (N.M.)
It's not all bad news
Despite the grim circumstances, the report noted some hopeful improvements from 2019:
- Parks with significant concern levels in at least one of the air quality categories fell from 96% to 70%.
- Significant concern levels for unhealthy air fell by 52%.
- Hazy skies decreased by 94%. (Seidman notes the report attributes this "to the implementation of several clean air regulations.")

Today's powerful photo is from staff photographer Marcus Yam. On a bright and nearly cloudless day in the West Bank village of Burin, hundreds gathered to bury a 10-year-old boy named Amro, who had been shot and killed by Israeli soldiers. Yam captured one boy's grief.
