Trucking bees around the country from crop to field to orchard is big business. That is one reason why we are losing bees to colony collapse disorder, so much travel is very stressful on the immune system. They should, instead,
encourage bee-keeping in/near the crops/fields/orchards and let the bees remain in place and calm.

They have to truck them because their aren't enough bees in the habitat naturally to pollinate our food supply.


And the bees would starve if they stayed in one place.
Once the main crop of the region is harvested there are not enough other flowers.
