Clearly, the "debate" is settled, but there's nothing wrong with pointing out even more little known facts about Christmas tree farms and how they benefit eco-systems.
Here's a link to an article about a tree farm in North Carolina, which was recently bequeathed to two farm managers along with lots of acreage around it. They are going to sell it to a conservancy group to maintain it as a public use outdoor recreation area, rather than sell to developers.
hmmm....tree farms or more mini-malls? gee, that's an easy choice in my mind.
