@indigomoth - With a Starbucks on every corner of the world (two on some corners!) it's hardly surprising demand for coffee is going up.
I've heard speculation that chocolate prices are going to sky rocket in the next few years as more and more people in poor countries start becoming less poor and more able to make the decision not to work on backbreaking farms to make the stuff.
I wonder if green coffee bean prices will go the same way. It's a good thing of course, because exploitation of workers is obviously wrong, but I hope another solution can be found before coffee becomes as valuable as caviar.
