Idea for the pier

Dear A.Camille

I have been thinking about the vegetation, and i think that the plants and trees can be use to help clean the canal too, it might not be totally clean, but it could helps. So I want to use the properties that it circulate the air and the water, and trapping the trash to be part of the function the pier have to make the environment better. This could link to the transportation as the boat can be dragging the plant along and picking up the trash while the boat is going.
