Hello to all...

The following excerpt was recently posted:
********************************
At an international meeting of entomologists (scientists who study
insects) in Basel Switzerland in March, experts warned that genetically
engineered (GE) Bt crops are exuding 10-20 times the amount of toxins
contained in conventional (non-GE) Bt sprays, and are harming beneficial
insects (such as ladybugs/ladybirds and lacewings) and
++++++soil microorganisms ++++++ and may likely be harming insect-eating
bird populations.
********************************

Is anyone aware of any published literature discussing the negative
impact of BT crops on soil micro or macro organisms ?
