David Nash, Ash Dome

Is this allowed?
With Ash Dome living trees are turned into an artwork. What image of nature would the artist have? We do understand that a tree is cut in the shape of a bird. The taste is not up for discussion, isn't it? With this bird there is nearly nothing left of the authentic of the tree. With this the artist is allowed to few the tree as something to manipulate.
We also do understand that we restore or simulate the original condition of the tree and its surroundings.
With Ash Dome, the lower half of the trunk is manipulated, and the upper part of the tree has is original form. The artist takes a middle position with partly an artificial and partly a natural form of the tree.
This artwork is allowed of course. This artwork has been created in the Century of the Human. Then it could be said that the Ash Dome makes us happy because the trees are dancing in a circle.
Recently we are in the Era of Nature and more and more critical sounds are heard against the manipulation of nature for the benefit of the human being. I'm curious to know what we say ten years from now about Ash Dome by David Nash.
