I dunno, if you were offered the straight choice of rain and dew filtered by purifying mountain, to human faeces, urine and tampons filtered with purifying chemicals, which would you choose? For me, well I made my choice. Though I do agree with Lizzie about the problem with bottles. We recycle, but still plastics are not really a desirable option for any forward thinking person. Simply posting this thread has however reminded me that there are local natural sources I should avail myself of, even if it takes an extra half an hour a week or whatever, it's a better option than buying plastic.
