Is it just me?

We just received an order of the soap nuts that we use for laundry, and in time too, since Mount Washmore awaits. We ordered it from a site called Alter Africa which is a site dealing in equitable commerce, and sells a variety of exotic and natural products, some of which are organic.
But those styrofoam packing nuts just don't sit right with me, it seems like such a contradiction. Is it just me? I know that sustainable commerce and environmental responsibility aren't the same thing, but in my head they complement each other. I searched the site to see if they mentioned using some kind of vegetal version of styrofoam, but nada. So though I'm happy for my order, it's just a tiny bit tainted. Guess I'll be stashing those nuts along with all the others I've kept and reusing them to send out Christmas packages. (Maybe that's what Alter Africa did?) Hopefully my recipients will keep the styrofoam moving around the world!
