I think the concept for this installation is brilliant and I understand why she exposes the roots rather than standing the trees upright as originally intended. The impact of the message seems better in the photo with the juxtapositon of people and the tree roots rather than the overall shot which looses a lot in translation. Definitely an installation that needs to be experienced for the full impact. Glad to see it will go to Copenhagen next.
One stump is equivalent of a 20 foot container imported from africa and then they are going elsewhere so i hope the point is made well bearing in mind the carbon taken to get these stumps here. In fact the total cost could have gone a long way toward replanting the origin rainforest.. As wood being imported for timber has to be baked to kill any bugs, I wonder if these were and if not how the phytosanitary or vets certificates were dispensed with. I recall when the Japs imorted a container of english oak acorns to plant and some bright spark fumigated and thus killed them on import.
Whatever, you got to allow a little odd art and as a temporary purposeful display yes they are impressive to me and I hope to others too.
