Come celebrate Earth Day with the UA! There will be several different areas, or "cities," to explore – the cities include vendors, research presentations, entertainment and of course, the University of Arizona's sustainability groups. The vendors promote sustainability with their products. The research tent will feature professors and students presenting current/past research projects involving renewable energy, eco-friendly tips and observed effects of resource usage. There may even be demonstrations! The entertainment city includes bike art, face painting, rock wall and cooking demonstrations. The University has many groups that promote sustainability such as Eco-reps and Compost Cats. These and many other groups will have tables in the UA Sustainability city. There will be a "Sustainable Art" contest for UA students and local artists. There will be live music from local bands on the stage of the mall starting at 5 p.m. As the event comes to a close, the eco-reps will present Fire Dancers and the UA Astronomy Club will bring out its telescopes and host a mini star party.
