OK, I'll be the voice of dissent. There is absolutely no way I would ever tolerate a fake tree. Ever. And I'm allergic to the real ones.
When I was growing up, we would cut our tree from the area of the power lines (this was in Maine and CMP was happy to have people poaching the trees that would eventually have to be cut anyway). I have no problem having a tree that was farmed. I'm not sure what the issue be there. I mean, we're talking about a crop. The difference between a crop tree and corn is growing time... and tree farms stagger plantings so they don't clear cut like corn farmers do. I would, however, object if supplying Christmas trees meant clear cutting wild trees like they do/did in lumber/paper areas, but it doesn't. Plus, my community recycles (yes, mulches or composts) all lawn cuttings, tree and shrub trimmings and Christmas trees, so there is an added bonus there.
With an artificial tree, real trees are still cut (for the pole and the box it comes in), ores mined (for the metal in the limbs) and plastics produced. Pre-lit trees are essentially disposable, since people like to throw them out when the lights no longer work, ditto when any tree becomes afflicted with oddly bent limbs and the color-coding rubs off and you can't figure out how to put it together any longer. I doubt they're recyclable, since the different materials are so mixed in their construction.
Yeah, when we get to the point where we don't want to deal with a real tree, I'll string lights in an indoor ficus. (of course, they're so persnickety about being touched and otherwise insulted, I'll probably end up with a dead ficus stick with some lights in it.
