Well, look what we have here - it's the immediate outcome of two countries' different policies regarding the state of their forests. On the left, you can see the German trees standing (admittedly, not so) tall, and on the right side, you have the Czech Republic's shaven trees looking a bit naked and lacking in leaves. It's funny just how easy crossing the border can be when you're in Europe.
We don't know what those Germans have been feeding those trees, but we can only say that they've come out looking healthy and green. Good on them. The world could always use more trees.
