The popularity of Nalgene bottles has risen and fallen on the sustainability wave.  Sure, reusable containers for water are cheaper and more responsible than buying bottled water.  Then people started realizing that the plastics come from fossil fuels (oops), and they contain polymers that might be toxic, like BPA.  OK, then people started buying metal bottles for their water.  Careful with that one: don't get aluminum.  Same problem as plastics, with high-impact extraction of the material, it's not renewable, and it may be toxic enough to contribute to alzheimer's.  Easy answer: use stainless steel.  If you don't know if your bottle is aluminum or steel, find out or get a new one.

This got me thinking and I realized I have been using plastic wrap and aluminum foil at home.  The shame hit me, and then I wondered what would be better.  Wax paper is renewable, and burns readily without toxic gassing.  I'm wondering if I can get cellophane, too.  Since it's derived from wood pulp, it's got to be better than plastic, but I'm not certain it's the best choice.  It's biodegradeable at least, but the production involves some toxic chemicals.

Regardless of what wrap product I buy, I think the best choice is to put leftovers in reusable containers whenever possible, and less plastics.  I see more Pyrex and Corningware in my future.
