Well, I'm not sure what your second post said, but addressing the first:
Perhaps you could elaborate?
Are you asking for tips on seasonal decorations (a riot of tinsel, red and gold, 70s kitsch); wondering what one might use to replace the traditional green plastic (in which case, I saw a great stack of toilet rolls featured on Twitter); pondering a philosophical question (I have had Not Enough Alcohol for that)?
Or did you actually, possibly in your second third or fourth language, intend to ask what to do with a Christmas tree once it's done with and the most ethical way to dispose of it? (plant in garden, burn in huge hearth for the next month, send to council for woodchipping)
