The document summarizes activities organized by an Eco school council and Erasmus+ strategic school project group to promote clean nature and saving resources. The activities included drawing and displaying large images of "pigmen" to depict litterers, coloring garbage containers pink, and stopping drivers to distribute small images of pigs and bags for rubbish to drop in the pink containers. Children from the local kindergarten joined in the activities. Students also wrote slogans about saving energy and not littering that were exhibited in a poster show about climate change.
