Coffee for the Greater Good

I hear a lot these days about "Fair Trade", "Sustainable", "Green" and "Organic".  Most of what I have learned and heard was through word of mouth.  My perception is that is true for you, too:  you've heard of these campaigns and are confident they are inherently good, though you don't really know the details.  I'll be creating four respective posts on these relatively new yet extremely popular initiatives to the coffee world, and I'd love your feedback.
