Anna and her friends in Quito, Ecuador, collect trash and reuse it in creative ways. They collect empty milk boxes, compress them, clean them, heat them, shred them and turn them into solid bricks which can be used in various ways. For instance they make furniture, handbags, roof tiling and even a house – for which 1.2 million milk boxes were collected! In this way, Anna is saving 11 million milk boxes every month and helping reduce environmental pollution. Video Credit: NasDaily
