Mobile Garden is a garden on wheels

With everything and everyone getting environmentally conscious the ‘Mobile Garden’ concept from American artist Joe Baldwin is a good idea, but somewhere it is not also. The mobile garden concept is a rail car that the Chicago Transit Authority will be driving around. It is actually a regular train but with one cargo of a flowerbed. The much required green space certainly looks good and refreshing, but my question is if it’s really required. Technically, its just additional weight that the train has to haul around, that only adds to the energy consumption. This is a green project but has a slightly ‘un’green way of doing it I guess.
