Got a green product, service, or program to promote? Do it by being a sponsor of Ohio State’s fourth annual Wooster Campus Scarlet, Gray, and Green Fair. It’s on April 19 at OARDC in Wooster. Becoming a financial sponsor of the event lets individuals and organizations “demonstrate their commitment to and support of a healthier environment and a more sustainable society,” says Ohio State’s Allen Zimmerman, chair of the event’s planning committee. The deadline to sign up is Feb. 15. Last year’s event drew 2,000 people. Call 330-287-1263, e-mail email@example.com, or click here for details.
