I wanted to share a little tradition that my family and I try to do every year for Yule. We don't cut down a tree to celebrate or decorate. Instead we adopt a sapling, or a younger tree and decorate it where it's planted. After the holidays are over, we clean off the decorations and leave behind harmless seed feeder cones for the animals that tolerated our silly fun. Not sure if it's low impact on the environment, but we avoid using tinsel and other polluting decorations.
