Ouch! Trees have feelings too

This afternoon I was at our city building which has a large concrete mall area with a low wall, and one round opening for a sycamore type tree--the type with the peeling, multi-colored bark. I'm guessing it's about 40 years old to judge from its girth. They left enough space in the original landscaping for it to really spread out.  The trees on the other side of the wall are spreading too, so it's getting harder to see the tree.  But up close you can see that huge hooks have been screwed into two lower limbs on which to hang "art."  One looks like it might be an elongated bell, the other a crooked globe trapped inside metal toothpicks.  They are BIG and HEAVY and in my judgement, not nearly as beautiful as a tree spreading its limbs to kiss the sky.  I'm afraid this is an example of tax supported "public" art--ugly rusting blobs of metal sitting around city buildings usually are. I have no idea why the artist didn't suggest an appropriate hanger for the art so the tree wouldn't need to be damaged and defaced.
