The question is, what do we all do with the ones we have? Do they just fill-up the landfills and leach BpA into our watersheds?
We have at least a half doz.(used to be more) of these bottles at home because we used to do a lot of outdoor activities(backpacking, rock climbing, etc.) where we needed to take our own water, and sometimes pack our own waste out, and not have it leak all over the gear in our packs. I guess I could designate a couple more of them for waste, but what about the rest? How do I even know if the alternative is any safer? Will I have more bottles to throw out a decade from now? From my childhood, I remember when CFC was being phased out of use as an aerosol propellant and replaced in many cases by HCFC which some argued was almost as harmful or more harmful to the ozone than CFC. Sigh? Some days I wish there was someone who had all the answers and would do the important decision-making for me.
