I just came across this fascinating exhibit at The Contemporary Jewish Museum in San Francisco. The exhibit is titled, "Do Not Destroy: Trees, Art, and Jewish Thought" and is a meditation on Ba'al Tashchit and the role of trees in Jewish culture. In addition to the works on display inside the museum, there is an interesting installation in the museum's courtyard that attempts to engage and foster an awareness and appreciation for the spatial and material qualities trees provide city dwellers. The work raises questions about the sustainability/livability of modern cities and what it means to be rooted/rootless in a globalized world. Enjoy.
