Hi Doris,
the problem is that at this time the bees are not dying in the fields. CCD remians an american problem, it does not suprise me at all that they have an issue.
In your own submission of evidences there are big big holes, in the austrian study they decetcted use of illegal pesticides, thats why they are illegal. neonicotinoid pesticides can cause issues especially if the seed is not propely coated, but so many things are not great for the world that we do, using toilet paper destroys forests, driving cars, and so on. Going pesticide free is not going to happen either.
