I have always considered it as a show, while also hoping it might produce something beneficial.
From the last paragraph;
Given that neonicotinoid bans elsewhere have resulted in significant growth of bee populations, there's a strong case to be made for applying the precautionary principle.
In reading what is going on in countries that banned neonics.. it started out that there was little effect, in fact some claimed no change at all, and that was TRUE, but as time passes, and continues to pass, the changes are beginning to become apparent.
People have this problem with time. If they do something and see nothing happen because of what they did in the short term they think its fine. When they make changes and nothing happens in the short term they think the change was ineffective. We live too short a time to see the effects of some of our actions. Just the proof that these insecticides are showing up in the wax should be enough to convince anyone that there is a danger, but... money is all powerful.
