Cover art for We Work The Black Seam lyrics by Sting

I think the Carbon 14 lyric is deliberate. It means to me that as dangerous the "machines that they can't control" are, humanity will always be more dangerous. (Based on the fact that Carbon 14's in us but not in nuclear waste)

Alternatively, it could be a reference to carbon dating, which would underline the plight of the British mining industry. I don't think this is as likely though, it seems a bit far-fetched.

Now that you and Balti mention it, modern man has been around for 11000-13000 years and seems to be on the verge of collapse. Maybe our deadly 12000 years are closing? (Now that that's said, somebody'll start a 2012 post and get 100 replies. Go figure)

Not Valid

it's just a rhyming device. but again, no amount of radioactive elements are safe in humans. it's only safe because it's .000000001% of most carbon....if you had a chunk of any pure radioactive element, it would be just as deadly as any other.
