If the basis of her concern was the needless destruction of her butterfly garden, it may seem baseless to those who see a butterfly garden as nothing more than some quirky, frivilous personal aesthetic choice. For those who have a genuine concern for the various endangered species of butterflies in Ontario and the impact this is having on the province's biodiversity, and by extension, the implications on the interruption of natural pollination patterns in the Niagara Fruit Belt, her concern is not baseless, and the added expense of rejigging the sidewalk to preserve the butterfly garden not really for no good reason.
