As part of the festive season this year, many of us will either buy a fresh Christmas tree, or we will bring an artificial one down from the attic. Either way, a Christmas Tree often forms an important part of the festivities. According to the National Christmas Tree Association, in 2012, US consumers purchased 24.5 million “real” trees compared to 10.9 million artificial trees. However, of those that displayed Christmas trees in 2012, 83% had an artificial tree. While many people believe a traditional live tree contributes to fighting climate change through carbon sequestration, others claim that an artificial tree can be used year after year without the need for fertilizers or pesticides. But which of these options is better for the environment?
