PolliciMetri is based on the concept of ecological footprint (a measure of human’s demand on Earth’s ecosystem, expressed in ha of land), and calls for the visitors’ participation to build a collective visualization of the community’s resources consumption.
The goal of the installation is to express and visualize a participated responsibility on the issue of resources consumption, and to give a tangible measure of this consumption. So the question was “How big a consumption do the group of visitors make during the installation’s opening time?”
It turns out that by the end of the exhibition, the group of about 250 participants had an extimated consumption of an area of landscape (= an ecological footprint) equal to the whole city center, some 1.5 sq km.
The collective visualization provided by the installation let us have some insight on what kind of consumption had the biggest consequences in terms of ecological footprint: Beef meat was by a long distance the 1st land consumption cause, followed by Car use and Coffee consumption (surprising?), after which Phone usage almost equalled Pork meat consumption.
With these datas, visualized and built with the participation of the visitors, we organized an open visit to discuss the results along with some possible reduction strategies.
