I have very mixed feelings about bottle water. First...unless you look for it...most bottled water does not have flouride. The only fillings I have were cavities I developed when my family lived where there was unflourinated well water. I realize the amount of flouride needed for healthy teeth is very small and I probably get it just from the amount of tap water I drink to brush my teeth...but I still think it is a concern if you NEVER drink tap water.

Secondly, yes bottles are very recyclable. But that statement overlooks the energy involved in recycling. The bottles are not "re-filled" but melted down and remade...all that requires electricity, etc.

Come on down to the harbor in our town and count the water bottles washed up.

Now, instead of taking bottled water to the gym with me...I fill a reusable bottle with ice water. It goes in the dishwasher.

You can take an EMPTY water bottle through security and fill it from a drinking fountain in the secure area at US airports. I also saw this done in Heathrow.

So, yes....we use them. But I try and find other alternatives whenever I can.
