Re: “China may finally be taking air pollution seriously” (editorial, 2-6).
There was an amusement park next to the Asarco smelter in the 1950s. Rides were nine cents on Wednesdays. Summer air tasted of sulphur, and there must have been arsenic and lead in the dust under the go-carts. We didn’t know; no one ever talked about it.
Today the pollution from coal is well understood. Thank you for reporting on it, including the startling fact that deadly pollution from China, some from U.S. coal, is crossing back over the ocean to us.
It is a relief to know …
