Bees don't pollinate grass and trees - they pollinate flowers, which don't cause hay fever.

Those don't sound like organisms that anybody actively wants to lure, but these bugs are helping to pollinate the plant.

While some bee-keepers aim only to produce honey, many others rent out their hives to farmers who need the insects to pollinate their crops.

They are also, not incidentally, highly useful to human society, producing honey and beeswax — both of which are used in a wide range of products — while also pollinating the plants that feed us.

The modest ranch house stood in the middle of an oak tree grove where he and his wife have lived for more than 25 years, running their bee pollinating and honey-making service.
