Chin Chih Yang sees that pollution has become a pervasive part of our lives. His large-scale 123PollutionSolution 2010 project transforms thousands of used aluminum cans into a colorful landscape with its varied topography. Yang collected discarded cans found in New York City trash cans left by students and parents from a local School. Ubiquitous concavities and hills, slopes and peaks, the installation features cans that are bunched into various abstract and geometric shapes. The structure represents an otherworldly utopia constructed out of salvaged waste.
