Some people have claimed that wind turbines cause (so far as I know, unspecified) problems to bees, which then are unable to pollinate the plants that rely on them for this service.
I would also like to know if there are studies on the electromagnetic pollution generated by wind turbine farms on the magnetic detection of flowers by bees sensitives hairs ? It is pretty hard to imagine that there are no effects from these massive electromagnetic field generators on the very sensitives and delicate bees already to often high on pesticides.
