These beautiful sculpture installation pieces are a great example of art combined with (down to earth) function. Located in Toronto’s Don River valley, the structures are clearly visible from the busy Don Valley Parkway. The Elevated Wetlands are a group of large polystyrene (same material as soft coffee cups) containers filled with plastics (like bottles, shredded car tires, etc.). The plastics hold soil, and the soil supports plant life. Water from the Don River is pumped, using solar energy, into ponds, and from the ponds into the polystyrene containers, where it filters through until it is released back into the river, much cleaner than it was when it started.
