Georgia Southern University's Center for Sustainability is preparing for a full day of "going green" during its second annual GreenFest on Saturday from 9 a.m. to 1 p.m. at the Bulloch County Courthouse lawn, 2 N. Main St. "We hope that visitors will learn that it's easier than they might think to make green choices," said Lissa Leege, Ph.D., the center's director. "We have the technology to reduce energy and water use and can make the choice to reduce waste and eat sustainably grown food." This year, GreenFest will feature three workshops: "Green Your Gameday — Sustainable Tailgating," "Green Your Lunchbox" and "Create Your Own Worm Compost Bin."
