Georgia Southern University's Center for Sustainability has teamed up with the University Wellness Program to host a number of events throughout April that are designed to improve and protect the environment and change behavior when it comes to food, energy, water and waste. The focal point is "No Impact Week," which began Sunday and lasts through next Sunday. "This week shows our commitment to sustainability and seeks to educate and inspire with an engaging and diverse slate of events,'" said Lissa Leege, the director of Center for Sustainability.
