Real Christmas Trees Greener? Healthier?
"Greener" says, Clint Springer, a biologist at Saint Joseph's University in Philadelphia. Well, maybe "greener" but not necessarily healthier. "Real" trees kept for several weeks in a family's home can cause allergies, and that's a great reason to stay away from real trees for lots of people. We need some PhD's in the neglected field of "unintended consequences," people who were liberal arts majors in schools where the liberal arts are taken seriously, to help their narrowly focused engineering and applied science friends look at the bigger picture. (I would add politicians to that list too, but I despair of them.)
