CCD is a set of symptoms that as i think about them come down to a reduction of quality natural forage opportunities. Pesticides and the neonics are one contributing factor. I haven't read the di Prisco, et al study referenced by WLC so it may be that the neonics are worse (cause more harm) than we have so far concluded. But I think of far more importance is our attitude towards the natural world - humans don't know everything yet - and our best science sometimes gets it wrong.
I wish I had all the answers but I don't. Humility, taking the time to look at the motives for 'cide use, remembering that miticides are often used by beekeepers and that there often are competing motives, are a few of the things I try to keep in mind when discussing this topic.
Oh and @drmanhandan sqkcrk is an abbreviation of the name of Mark's apiary.
