Last year I wrote about the maize mazes carved from growing corn fields that reminded me of the mysterious Nazca Lines in the Peruvian desert. I just discovered Polish artist Jarolslaw Koziara, whose work falls more into the category of land art installation, with carefully crafted plantings to create geoglyphic imagery.
The “Art for All Seasons” shown above is stunning in its own right, and the single and double fish, planted on the Polish-Ukrainian border is even more noteworthy. The fish is a deeply symbolic image that crosses many cultural, national and religious boundaries, often meaning abundance, creation and unity. In this case it is a more literal image, showing the unity between two countries whose borders have shifted fluidly for centuries: Nature trumps politics.

I think nature in the form of water will eventually be what people fight over unless we can bring population under control. I don’t see that happening.
Water has definitely been an issue historically and will continue to be the case as people constantly outgrow their local supply. Not to mention the cycle of human impact-climate change-less annual snow pack-lower water sheds-human impact etc. No obviously easy solution, and as we enter Monsoon here in India it’s easy to wonder “what water problem?”
