I honestly never thought about the notion that buying and selling used goods could be good for the enviroment. My omnivorous diet may be considered damaging to the earth to some, but it would not be hard for me to make up for such a "barbaric" action and go the "retro" route. With a few exceptions, my basic taste in clothing is found in a thrift store. Plus, I like to look for old books, tapes, and CDs, as well. One person can be tired of something, but that same something (even with a little age to it) can be new and fresh to someone else. That is, as long as it's basically in good condition.
