"Green" is such an overworked word these days -- everything is described as being green, or good for the environment. New missionaries are often called greenies (in case you didn't know). They may not be part of the three Rs of recycling, but they can be good for your internal environment.

BYW, here's something for your Gee Whiz file: In French, new missionaries are called blue rather than green. Now you know.
