We just replaced our first artificial tree. It was 5 years old and I got tired of trying to locate the burned out bulbs. The new one has LEDs and even a remote to change the colors and make it flash. But, to be honest, it's not a Christmas tree to me. It's just a flashy decoration.
When I was a kid, the Christmas tree was always a scrawny little Douglas fir sitting on a box to make it look taller. It had a few strings of real colored bulbs, some very old and shaped like things, lots of glass ornaments, and was buried in lead icicles. Mother would spread some cotton around the base to cover the wooden stand. It smelled like a tree.
One year, my oldest brother who was a truck driver, stopped along a road somewhere up north, walked into the woods in the dark and cut down a little tree and brought it home. That one was really pitiful, but we loved it.
When our kids were growing up, we went to a local cut your own tree farm located under some high voltage power distribution lines. The trees were Scotch pine that were really bushes trimmed to a tree shape. But they smelled good too. My wife made some decorated green felt to place under them to put packages and our nativity scene. One year our dog ate the manger and I had to make another one.
When you figure that artificial trees are made of metal and petroleum derived plastic, and are shipped all the way from China, they are probably not the best for the environment, especially since they end up in a land fill. Our city collects real trees and composts them. Of course. of you really want to be environmentally friendly, don't have a tree. There are other decorations you could put up and a real wreath smells nice too. But, my wife isn't buying that.
