Green Challenge 365 Educational Calendar

Social Design Green Challenge 365 Educational Calendar by SUNG HO NAM Green Challenge 365 is an educational calendar created to encourage the saving of wooden disposable products. The set includes a calendar printed with a bare tree, one leaf-shaped stamp and a green ink pad. One leaf stamp may be added each day when disposable wood items such as paper cups, wooden chopsticks and paper sleeves are avoided. As participation continues, the printed tree fills with green leaves. The growing image shows the time and effort needed to raise a tree. The calendar is distributed to educational institutions without charge.
