Reason Magazine offers this piece: Are biotech crops killing America's bees? Apparently the author thinks that the Sierra Club is using this opportunity to bash the bio-tech industry. The author, Ronald Bailey, Science Correspondent, states:
colony collapse disorder is not confined to biotech-friendly United States. Hives are collapsing in biotech-free Europe too. The head of the German beekeeper's association says there has been a 25 percent drop in bee populations in Germany. Bizarrely, one particularly irrational German beekeeper blames biotech corn even though the Germany's biotech corn is only 0.06 percent of the total crop. Last week, the Irish Times (subscription required) reported that in Britain 30 per cent of hives inspected so far have been lost and that hundreds of thousands of colonies have collapsed in Spain. Beekeepers in Poland, Greece, Croatia, Switzerland, Italy and Portugal have also reported heavy losses.The only thing that is clear is that the cause for what is being called "colony collapse disorder" (CCD) is not at all clear.
