Rooftop Gardens on Wheels

There has been a rash of gardening innovation lately–chairs with built-in planters, modular apartment buildings with spaces for parks at each level, and my favorite of the bunch: rooftop gardens on wheels. Yes, you guessed it, people have started putting gardens on top of buses. The theory is that all those plants will help absorb at least some of the exhaust that each bus creates. Just imagine if the buses ran on clean energy how much more those little succulents would do. Of course they wouldn’t be great for food gardening (at least not with the buses running on diesel), but who knows what the future might hold… we could give a whole new meaning to “fast food.”
