Could it be?
Re the good news on the surprisingly low smog levels so far this summer in Salt Lake County ("Smog high, but experts are seeing good signs," Tribune, July 11), a factor that was not mentioned in the lower-than-expected levels was that Kennecott's open-pit mine has not been at full production for some time due to a giant spring landslide.
Could there be a connection between the better-than-expected air-quality levels and the idled mine?
Sure is worth exploring. Perhaps less mining is good for our health.
