A celebration took place yesterday in the Great Hall of the Memorial Union.  But it was not athletics or academics that was being celebrated but the strides that Iowa State is taking in the field on sustainability. The event was appropriately called Sustainapalooza. The event kicked off with a greeting from Merry Rankin from the Office of Sustainability and a speech by President Steven Leath. "I'm really proud of what's going on here," Leath said regarding the university's sustainability efforts. After his speech he headed over to the green carpet to cut the ribbon, opening up the area for students to walk through.
