It’s the thing I appreciate the most when I land at SFO — the air. I take deep breaths, and contemplate the beauty of the bay and the hills. And I breathe some more.

Then, back in Marin, I am awed by Mt. Tam and the clear, clean air. To see the clouds and the sun, to sense the pacing of the day…these are things you don’t get in industrial cities in China. It’s just grey. All the time.

So it’s interesting, this move by the Chinese government, to stop releasing the data. http://www.nytimes.com/2012/06/06/world/asia/china-asks-embassies-to-stop-measuring-air-pollution.html?_r=2 I wonder where they’re going.
