It is surprising how we can find abstract similarities within natural and artificial objects.
When walking in nature you come across the same shapes and forms, however not all of them belong there. The solid browns, deep greens of the fallen branches and leafs natural garbage are unnoticeable in their own environment. Not like the vivid neon greens and whites of plastic, the metallic shine of foil. They pop out, they don't belong.
In this set of posters "Natural Garbage" I highlight these similarities and contrasts to help the viewer notice and encourage action.
