Silver's Environmental Impact - Sundrop Jewelry

The answer is pretty rough, but shows that silver is several times more wasteful than paper or glass in straight energy terms. This is despite the fact that we use more glass and paper than we do silver. And it's not even accounting for most of mining's impacts described above - just the energy. I don't have a great solution to this.
