Consider some analogies: California Poppies, our state flower, contain some morphine and codeine, the raw materials for making heroin, an illegal drug. Therefore “This bill is about raising awareness to protect the health of our citizens. California Poppies contain morphine and codeine, illegal drugs. Illegal materials have no place serving as emblems for the State.” Let's get rid of poppies as our state flower.
Gold miners, breathing the dust of quartz in the milling and crushing of gold ores, died by the score in the mines during the Gold Rush, the event that led to the establishment of the state (gold mining also pretty much ended dozens of Native American cultures through direct violence and disease). So... “This bill is about raising awareness to protect the health of our citizens. Gold ore contains quartz, a known cause of silicosis. Toxic materials have no place serving as emblems for the State.” Let's eliminate gold as our state symbol.
Grizzly bears killed hundreds and hundreds of Native Californians and Mexican-Americans in the early history of the state. So... “This bill is about raising awareness to protect the health of our citizens. Grizzly bears contain teeth and claws, known killers of people. Toxic animals have no place serving as emblems for the State.” Let's eliminate the California Grizzly Bear as our state mammal. Oh, wait. We did one better: we eliminated the California Grizzly Bear instead. The last one was shot in the 1920's.
I've been on this topic for a week now (see here and here), and Silver Fox has a nice review of the many factual problems in the actual text of the bill (serpentine is not asbestos; it may contain an asbestiform crystal habit, but so do five other minerals, and it is they which are most implicated in causing disease), as well as a review of geobloggers who have been discussing the problem. Also, check out Andrew Alden's take on this at About Geology.
I do not want to belittle the problem of asbestos, lung cancer, and mesothelioma. These are serious enough issues, but going after serpentine is misguided, and I believe, actually hurting the effort at raising awareness of the connections between the two. The fracas going on today will be over, and in another month no one will remember the issue. But any child studying the state symbols over the coming decades will discover an interesting rock, but also the connection to asbestos and disease.
They're throwing the baby out with the bathwater, and since it has already passed the state senate, I fear they may succeed. If you are concerned about this, and you're in California, call your assembly representative or Governor Terminator with your views.
