The issue of “hive collapse” has been around for centuries. European bees at times were bred to combat this problem as early as the 1700’s.
There are thousands of different kinds of bees. The issue is complicated. I am presently skeptical that Roundup is the cause, but as a scientist, I will examine the evidence as it is presented. This study is interesting, but far from convincing.
“Agenda science” is difficult to detect, but remains a problem to the outside reader.
I'm just an old carpenter, so will bow to the expertise of your future findings.
I would, however, close by saying that the folks who own one of the largest honeybee pollination outfits in this half of the country are family friends, and their business is buzzing along quite nicely.
cheers :-)
