Air pollution is making it harder for bees and other pollinating insects to find food, according to a new study conducted by researchers from the University of Virginia.

Pollutants such as ozone (smog) and nitrate radicals, formed mostly as a consequence of car exhaust, are binding with the volatile scent molecules given off by flowers, the scientists found. This chemically alters the molecules so that they no longer carry a sweet scent, and do not attract pollinating insects to plants.

I would say it probably has something to do  with it but pesticides and things like that in my mind would be the worse culprit.  And remember this: Honeybees are the primary pollinators for 80 percent of the world’s food crops.  Bottom line is this. If the Bees Parish so do we.
