This photo was taken on July 13, 2011 in Guatemala while transporting over 3,000 eco-bricks from a classroom to the municipality. In the truck are the 3,000 plastic bottles stuffed with inorganic trash that a class of accounting students decided to collect and donate to benefit the construction of a Mayan Educational Center made with eco-bricks. The men seen in the photo are some of the members of the Mayan Council who are leading the construction of the Mayan Educational Center.
