Inspired by one of the existing eco houses in Edmonton—a house that strives to reduce its environmental footprint by reclaiming or reusing materials (wood, metal, etc.), and by conserving energy and maintaining energy efficiency—a wall mounted bookshelf was designed to carry a message that is congruent with the message of the eco house. By its very existence, the eco house raises awareness of the environmental concerns that are closely tied to our daily activities. Similarly, the bookshelf also acts as a sign that warns and reminds the viewer about existing environmental concerns, particularly those associated with our consumption rate as compared to the availability of natural, raw materials. In particular, it serves to raise awareness about our paper consumption rate in comparison to the growth rate of the forests.
