It is the unusual view out of a boat pointing to the ugly edge of the stairs of the palazzos and the water edge while driving at the Canal Grande in Venice. Millions of pictures are taken every day on this route, but 99 % of the tourists try to find the most picturesque views towards the houses and bridges and gondolas. With my opposed view, wich goes to the more ugly edge, covered with green alga I try to make aware of the rise of the Global Mean Sea Level - a consequence of global warming.
