Wrong! Ethanol is killing the bees. http://www.cnn.com/2013/04/02/opinion/flottum-bees-death/
Consider your source (CNN)...
There are lots of factors in Bee decline...pesticides, removal of natural food sources, removal of habitat, GMO crops, etc.
When our neighbors have their lawn treated, we have to shut up the hive for several days to keep the bees from the chemicals. Not only are the chemicals harmful, but the loss of natural bee food sources like dandelions and clover (which people hate in their “perfect” yards, but Bees love) are destroyed.
