Get the buzz on bees at this class, sponsored by the Peterson Garden Project, 7-8 p.m., July 31, at PGP's Learning Center, 4642 N. Francisco Ave.

Pollinators are key to our food system and their numbers have steadily been declining in recent years.

Liz Olney will lead the class in a discussion of the role of pollinators, the health of Illinois' bee population and what you can do to support area pollinators.
