There was a photo contest sponsored by the United Nations Environment Program in the early 90’s, to coincide with the first Earth Summit in Rio De Janeiro. The theme was “Focus on Your World”, and the winner was to receive an all-expense paid trip to Rio, where they would also pick up $20K at World Environment Day ceremonies. Somehow this image seemed appropriate to their call for images that would “heighten international awareness of our fragile environment” – I seem to remember a “shelter” subcategory. In any case, I had my bags packed but, uh, never heard back. There were 32K+ submissions, and a book was published of the winning images, which I just ordered here.
