The University of Arizona will celebrate Earth Day and the 10th anniversary of UA research at Biosphere 2 on Saturday with a day of activities that include hermit crab releases every half hour at the Biosphere ocean, and a sunset concert by Calexico.
Biosphere 2, 32540 S. Biosphere Road in Oracle, about 30 minutes outside Tucson, is adding to its regular tour events special lectures and panel discussions on the future of the Earth, energy, water and food; beach and rainforest tours; and groundbreaking for a vertical farm complex.
The research center also will include a focus on Tucson as the first UNESCO City of Gastronomy. Tucson-based chefs, growers, producers, distillers, ranchers, innovators and advocates will be set up in the main tent on the Biosphere 2 lawn.
