                <div class="PlainText">So, to stir the pot a bit,
                  wouldn't healthier honeybees be good as they wouldn't
                  spread disease to wild bees?  And the efforts being
                  put forth by farmers to include wildflower strips on
                  their land, that wouldn't have happened without the
                  threat to honeybees, but should also benefit wild
                  bees/pollinators.  I just think that we can't possibly
                  help one pollinator species without helping all.  I
                  understand the messaging to the public is wrong, but
                  what the public really cares about is access to the
                  variety of food they want.  Monocrops aren't going to
                  disappear anytime soon, and honeybees are needed to
                  maintain those.  It's not an idea situation, but if we
                  take measures to support honeybees I think it will
                  only support native pollinators as well.  I'd love to
                  hear discussion...<br>
