The first team, "Plastic Earth," made a landscape out of used plastic bottles, and bamboo. Their effort was to show passerby's what could end up in our parks if people don't recycle.
The second team, "Take a Tree, Leave a Tree," had a large piece of dry wall and invited anyone to come draw a tree on the mural. If one drew a tree they were invited to take a spruce tree seedling to plant.
The last team, "Grab a coffee, grab a book, grab a seat," invited you into their street side cafe. With a mini book shelf and some large comfy chairs you could read about architecture and landscape.
