As part of its "Greener Ravenswood" effort, the Ravenswood Community Council is hosting a Sustainable Speaker Series 6-8:30 p.m., Feb. 27, at Dolce Casa Cafe, 4947 N. Damen Ave.

Topics include composting — from apartment bins to commercial businesses — beekeeping and how to decrease the amount of pesticides used in lawn care.

Jordan Rose of River Valley Farmer's Table will also be on hand to talk about his family's mushroom farm and their new Ravenswood shop and cafe.

The cost is $5 for RCC members and $10 for the general public; appetizers and drinks will be served.
