One Trees, Two Wheel Bike Ride April 20, 2008

Come take a bicycle tour of Natalie Jeremijenko’s One Trees Project. The day’s events will look at air pollution through a series of xDesign Environmental Health Clinic experiments. Among them, we will test the One Trees for CO2 levels and other airborne toxins. Participants will also help to render air pollution evident by wearing Clear Skies Facemasks that visualize urban air quality. Please call Southern Exposure at 415-863-2141 in advance to reserve a spot on the tour. Bring your bicycle!
