It's a little early to think about throwing your Christmas tree to the curb, if you even have one yet.

We've all seen these withered forms, needles starting to brown, discarded in alleys and gutters after Jan. 1. Sadly, one often finds homeless folks in such places, in basically the same condition, year round. Via Ads of the World.
