Don’t have a tree yet? Instead of killing one get a potted tree via @SFUrbanForester, which will plant it after the holidays are over:
Or get a house tree and decorate it every year, like us 
Listen the whole cut fir tree tradition only came to the US via the German wife of George III. Jesus didn’t have a tree and if he did it would have most like been a palm or olive tree. Decorating for the holidays is a fun tradition but you can do it in a greener way.
I asked my mom for a donation to @SFUrbanForester for Xmas, because our city is horribly undergreened. But there are many such local groups like it and national/international tree planting efforts like #TeamTrees
