Yes, June 22nd-28th is National Pollinator Week. Animal pollinators are needed for 90% of all flowering plants, and at least a third of human food crops.
We would be screwed without pollinators.
The folks at Pollinator.org have a bajillion PDF handouts for you, as well as some nifty posters. Xerces Society also has many PDF documents about how to garden to promote native bees. (You did know honeybees are an introduced species in the US, right?)
BTW, while Michigan is pretty screwed up otherwise, the Governor has officially declared it Pollinator Week in Michigan (PDF).
