With a lack of public restrooms in the city, certainly we could find some use for these P-Trees. Open your mind, New Yorkers! A Dutch design studio created these mechanisms and debuted them at Denmark’s Roskilde Festival, providing a nice open-air alternative to the Porta-Potty. The temporary tree-friendly urinal is attached to trees using straps, making peeing in public slightly more sophisticated. Would these work in the city's parks, perhaps with a privacy shade?
