It seems an increasing number of people are interested in a green holiday season. Numerous books are on the shelves, such as Green Christmas: How to Have a Joyous, Eco-Friendly Holiday Season and A Greener Christmas, if that's any indication. But it's tough to know what's green and what's "green washed," products that masquerade as environmentally friendly, but aren't really. It's an important time of the year to read labels, ask questions and do your research on products you're interested in purchasing.
