Which is more environmentally friendly; a fake Christmas tree or a real one? If you want a real tree for Christmas, which species should you choose so you don't end up with the needles falling all over your floor a few days later? Whether you've got your Christmas tree or not, you'll find answers to these questions and more in this video about the science of Christmas trees.

In this film, "The Science of Christmas Trees", videographer Brady Haran and University of Nottingham ecologist Markus Eichhorn went to a local seller and discussed the trees on offer. This film was unscripted and unplanned, designed to come across as a simple and casual chat, yet meant to inspire people to think a little more deeply about something they may take for granted, or may not necessarily think of as a topic of scientific interest.
