I think it's a forlorn hope ,,, tbe reality is that the vast majority of colonies in the vast majority of locations are incapable of surviving heavy
infestations of varroa and actually NEED to be treated, You cannot expect everyone to suddenly stop treatment for varroa and see what happens ... it's unrealisric. Bees are expensive commodities ... if you only have a few hives you cannot afford to lose them and ... if we did all agree and we end up with a majority of dead outs ... where do the replacements come from.
I'm TF but I advocate treatment if a colony shows (from proper testing) that they are not managing a varroa load. Perhaps your initial stance should be to encourage people to test and not treat those colonies that do seem to cope in those locations where they can cope. You cannot expect bee farmers to perform this way - time and commercial constraints prevent it. The easy and practical course of action is to treat for varroa and you have to accept that, for the vast majority of beekeepers this WILL be their chosen path.
