I seen an experiment where this guy put up a couple cordless phones around a few small hive colonies he owned.....this was before we had so many cellphone towers but were just getting to the point where we started transmitting more wireless signals. Most of them died off.....I think our electromagnetic pollution is at least partially to blame because it makes sense......and of course tinkering with GMO's and pesticide on everything we grow probably isn't helping either.. Bee's are really important to us.....so are sharks (And we kill them just for their fins by the millions every year). Oil spills....I'm not one of those tree hugging environmentalists but we are seriously screwing up our ecosystem and none of us seem to care.
