Trees pollute the public space? If mixing neighbors and trees causes problems, then the problem is with the neighbors, not the trees. Trees are awesome. Assuming sustainable low-pollen species are chosen, why not cover every building in green?

Trees don't pollute the public space; a view of inaccessible trees pollutes the public viewscape.

The same argument can be made against anything. I might have a car you can see. But you can't access it. Does this pollute the public viewscape? You might have windows or balconies that I can see, but I can't access them. Does this pollute the public viewscape?
